ABSTRACT Purpose: To compare the long-term ocular findings of children that were operated of congenital cataract before the age of two and that received an intraoperative intracameral triamcinolone injection or used postoperative oral prednisolone to modulate ocular inflammation. Methods: All patients who had previously participated in a clinical trial that analyzed the 1-year surgical outcomes of congenital cataract surgery utilizing intracameral triamcinolone (study group) or oral prednisolone (control group) were eligible to participate in this prospective cohort research. Patients’ medical records were reviewed, and the children underwent a complete ophthalmologic exam on final follow-up. Biomicroscopic findings, intraocular pressure, central corneal thickness, the need for additional surgical interventions, and findings compatible with glaucoma were the primary end measures. Results: Twenty-six eyes (26 patients) were included (study group = 11 eyes; control group = 15 eyes). The mean follow--up was 8.2 ± 1.2 years and 8.1 ± 1.7 years in the study and control groups, respectively (p=0.82). All eyes presented a centered intraocular lens. There was no statistically significant difference between the groups with regards to the presence of posterior synechia (p=0.56), intraocular pressure (p=0.49), or central corneal thickness (p=0.21). None of the eyes fulfilled the glaucoma diagnostic criteria, presented secondary visual axis obscuration, or were reoperated. Conclusion: The long--term ocular findings of children that underwent congenital cataract surgery and received an intraoperative intracameral triamcinolone injection were similar to those that used postoperative oral prednisolone to modulate ocular inflammation. This suggests that intracameral triamcinolone may substitute oral prednisolone in congenital cataract surgery, facilitating the postoperative treatment regimen and compliance.

RESUMO Objetivo: Comparar os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita antes dos dois anos de idade e receberam uma injeção intracameral de triancinolona no intraoperatório ou usaram prednisolona oral no pós-operatório para modular a inflamação ocular. Métodos: Neste estudo prospectivo de coorte, todos os pacientes que participaram de um ensaio clínico anterior, que analisou os resultados cirúrgicos de 1 ano da cirurgia de catarata congênita usando triancinolona intracameral (Grupo de Estudo) ou prednisolona oral (Grupo Controle), eram elegíveis para participar. Os prontuários médicos dos pacientes foram revisados e as crianças foram submetidas a um exame oftalmológico completo no acompanhamento final. As principais medidas de desfecho foram: achados biomicroscópicos, pressão intraocular, espessura central da córnea, a necessidade de intervenções cirúrgicas adicionais e achados compatíveis com glaucoma. Resultados: Vinte e seis olhos (26 pacientes) foram incluídos (Grupo de Estudo = 11 olhos; Grupo de Controle = 15 olhos). O seguimento médio foi de 8,2 ± 1,2 anos e 8,1 ± 1,7 anos nos Grupos de Estudo e Controle, respectivamente (p=0,82). Todos os olhos apresentavam lente intraocular centrada. Não houve diferença estatisticamente significativa entre os grupos com relação à presença de sinéquia posterior (p=0,56), pressão intraocular (p=0,49) ou espessura central da córnea (p=0,21). Nenhum dos olhos preencheu os critérios diagnósticos para glaucoma, apresentou opacificação secundária do eixo visual ou foi reoperado. Conclusão: Os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita e receberam uma injeção intracameral de triancinolona no intraoperatório foram semelhantes aos que usaram prednisolona oral no pós-operatório para modular a inflamação ocular, sugerindo que a triancinolona intracameral pode substituir a prednisolona oral na cirurgia de catarata congênita, facilitando o tratamento pós-operatório e a adesão ao mesmo.

ABSTRACT Purpose: To assess the anterior and posterior segments of full-term neonates over a 1.5-year period. Methods: The findings of full-term neonates who underwent ophthalmological examinations between June 2019 and December 2020 were analyzed, and the results were retrospectively recorded. Results: The study comprised 2972 neonates with a mean birth week of 38.7 ± 1.2 weeks and a mean birth weight of 3235 ± 464 g. The neonates were examined on an average of 49.3 ± 18.9 postnatal days. Of the examined neonates, 185 (6.2%) showed abnormal ophthalmological findings, the most prevalent of which were retinal hemorrhage in 2.3% (n=68) and white changes in the peripheral retina in 1.9% (n=55) of the neonates. Cases of optic disc pathologies (n=20), choroidal nevus (n=10), iris-choroidal coloboma (n=5), subconjunctival hemorrhage (n=6), non-specific retinal pigmentary change (n=4), congenital cataract (n=3), posterior synechia (n=3), iris nevus (n=3), corneal opacity (n=1), choroidal coloboma (n=1), iris coloboma (n=1), buphthalmos (n=1), anophthalmos (n=1), microphthalmia (n=1), lid hemangioma (n=1), and vitreous hemorrhage (n=1) collectively accounted for approximately 2% of all neonates. Pathologies that could potentially impair vision, which were detected by ophthalmological examination, accounted for 1.2% of all neonates (n=37). Conclusion: The most prevalent finding of the ophthalmological examinations of neonates in the present study was retinal hemorrhage. Ophthalmological examinations of neonates can help in identifying diseases that may affect their vision and are curable or may lead to amblyopia in the long term.

ABSTRACT Purpose: To evaluate primary intraocular lens implantation in the treatment of children’s aphakia in the Brazilian public health system and compare the outcomes among different age groups. Methods: Children aged 0-12 years old with unilateral or bilateral congenital/developmental cataracts and underwent primary intraocular lens implantation were included. Results: A total of 108 eyes from 68 children were evaluated, and the children were divided into four age groups (<7 months [mo]; 7 mo-2 years old [y/o]; 2-5 y/o, and >5 y/o) were evaluated. Nineteen eyes (17.59%) presented visual axis opacification as a postoperative complication, which was more frequently observed in the <7 mo age group (37.93%). The difference was significant between the <7 mo and >5 y/o age groups (p=0.002). Visual axis opacification was divided into two categories: pupillary membrane and lens cell proliferation. Eight eyes presented pupillary membrane, whereas 14 showed lens cell proliferation. Out of eight eyes with pupillary membrane, seven occurred in the <7 mo age group. The difference between the <7 mo age group and the 2-5 y/o or >5 y/o age group was significant (p=0.01). Lens cell proliferation was more frequent in the <7 mo and 2-5 y/o age groups, but the difference was significant only between the < 7 mo age group and >5 y/o age group (p=0.040). Glaucoma and glaucoma suspect cases were not observed during the follow-up period. Conclusions: The main complication found in the study was visual axis opacification, which had a higher incidence in children operated on or before the age of 7 months.

RESUMO Objetivo: Avaliar o implante de lente intraocular primária para tratamento da afacia pediátrica no Sistema Único de Saúde (SUS) e comparar os resultados em diferentes faixas etárias. Métodos: Foram incluídas crianças com catarata congênita e do desenvolvimento unilateral ou bilateral de 0-12 anos de idade e submetidas a implante de lente intraocular primária. Resultados: Cento e oito olhos de 68 crianças divididas em quatro grupos de idade (<7m; 7m-2a; 2-5a e > 5a) foram avaliados. Dezenove olhos (17,59%) apresentaram opacificação do eixo visual como complicação pós-operatória. Essa complicação foi mais frequente na faixa etária <7 meses (37,93%). A diferença foi significativa entre os grupos de idade <7 meses e > 5 anos (p=0,002). A opacificação do eixo visual foi dividida em duas categorias: membrana pupilar e proliferação de células do cristalino. Oito olhos apresentaram membrana pupilar e 14 proliferação de células do cristalino. Dos oito olhos com membrana pupilar, sete ocorreram na faixa etária <7 meses. A diferença entre o grupo de idade <7 meses e os grupos de 2-5 anos e > 5 anos foi significativa (p=0,01). A proliferação de células do cristalino foi mais frequente nos grupos de idade <7 meses e 2-5 anos, mas significativa apenas quando comparados o grupo de idade <7 meses com o grupo> 5 anos de idade (p=0,040). Glaucoma e suspeitos de glaucoma não foram observados durante o acompanhamento. Conclusões: A principal complicação encontrada no estudo foi a opacificação do eixo visual. Sua incidência foi maior em crianças operadas antes dos 7 meses de idade.

RESUMO Objetivo: Comparar os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita antes dos dois anos de idade e receberam uma injeção intracameral de triancinolona no intraoperatório ou usaram prednisolona oral no pós-operatório para modular a inflamação ocular. Métodos: Neste estudo prospectivo de coorte, todos os pacientes que participaram de um ensaio clínico anterior, que analisou os resultados cirúrgicos de 1 ano da cirurgia de catarata congênita usando triancinolona intracameral (Grupo de Estudo) ou prednisolona oral (Grupo Controle), eram elegíveis para participar. Os prontuários médicos dos pacientes foram revisados e as crianças foram submetidas a um exame oftalmológico completo no acompanhamento final. As principais medidas de desfecho foram: achados biomicroscópicos, pressão intraocular, espessura central da córnea, a necessidade de intervenções cirúrgicas adicionais e achados compatíveis com glaucoma. Resultados: Vinte e seis olhos (26 pacientes) foram incluídos (Grupo de Estudo = 11 olhos; Grupo de Controle = 15 olhos). O seguimento médio foi de 8,2 ± 1,2 anos e 8,1 ± 1,7 anos nos Grupos de Estudo e Controle, respectivamente (p=0,82). Todos os olhos apresentavam lente intraocular centrada. Não houve diferença estatisticamente significativa entre os grupos com relação à presença de sinéquia posterior (p=0,56), pressão intraocular (p=0,49) ou espessura central da córnea (p=0,21). Nenhum dos olhos preencheu os critérios diagnósticos para glaucoma, apresentou opacificação secundária do eixo visual ou foi reoperado. Conclusão: Os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita e receberam uma injeção intracameral de triancinolona no intraoperatório foram semelhantes aos que usaram prednisolona oral no pós-operatório para modular a inflamação ocular, sugerindo que a triancinolona intracameral pode substituir a prednisolona oral na cirurgia de catarata congênita, facilitando o tratamento pós-operatório e a adesão ao mesmo.

Resumen: Las cataratas son una causa importante de discapacidad visual en la población pediátrica en todo el mundo y pueden afectar significativamente el neurodesarrollo de un niño. Constituyen un problema fundamental en cuanto a su manejo y una de las causas más relevantes de ceguera tratable en los países desarrollados y en vías de desarrollo. La trisomía 21 es la cromosomopatía más frecuente, de características fenotípicas determinadas con un 60% de anormalidades oculares, entre las que se destacan las ametropías, queratocono y las cataratas. El diagnóstico clínico y la identificación temprana del tipo de cataratas, junto con intervenciones clínicas y tratamientos precoces, son claves para lograr resultados óptimos. Se presenta el caso de un recién nacido con síndrome de Down y catarata congénita bilateral y su manejo inicial.

Summary: Cataracts are a major cause of visual impairment in the pediatric population worldwide and can significantly affect a child’s neurobiological development. Congenital cataract management can become a very important problem and is one of the most important causes of blindness in developed and developing countries. Trisomy 21 is the most common chromosomal disease and it has certain phenotypic characteristics and 60% ophthalmic abnormalities, such as, ametropia, keratoconus and cataracts. The diagnosis is fundamentally clinical. Early identification, diagnosis, and appropriate clinical care are key to achieve optimal results. We present the case of a newborn with Down syndrome who was diagnosed with an early bilateral congenital cataract.

Resumo: A catarata é uma das principais causas de deficiência visual na população pediátrica no mundo e pode afetar significativamente o neurodesenvolvimento de uma criança, além de constituir um problema fundamental em termos de sua gestão e é uma das causas mais relevantes de cegueira tratável em países desenvolvidos e em desenvolvimento. Trissomia 21 é a cromossomopatia mais frequente e tem determinadas características fenotípicas com 60% de alterações oculares, como a ametropia, ceratocone e catarata. O diagnóstico clínico e a identificação precoce do tipo de catarata, juntamente com intervenções clínicas e tratamento precoces, são fundamentais para alcançar os melhores resultados. Apresentamos o caso de um recém-nascido com síndrome de Down e catarata congênita bilateral e seu manejo inicial.

Resumen: El resultado visual funcional posterior a una cirugía de catarata es influenciado por varios factores como la edad del diagnóstico, el tratamiento quirúrgico y la rehabilitación visual. Objetivo: Describir las características demográficas y clínicas de pacientes con catarata congénita y conocer el resultado visual postoperatorio en un centro de atención oftalmológico en Guatemala. Pacientes y Método: Es tudio transversal y retrospectivo. Se revisaron expedientes clínicos de todos los pacientes operados de catarata congénita en los años 2014 y 2015. Se registró la agudeza visual posoperatoria, edad del diagnóstico y cirugía, sexo, lateralidad, etiología y morfología de la catarata, factores de mal pronós tico visual preoperatorios y seguimiento posoperatorio. Resultados: Cincuenta y nueve pacientes fueron operados de catarata pediátrica en este período, con edades entre 1 mes a 13 años (mediana 48 meses) siendo 23 de etiología congénita (38.98%) incluidos para este estudio. De estos, 14 eran de sexo masculino, 16 bilaterales, la edad mediana del diagnóstico y de cirugía fue de 7 y 12 meses respectivamente. Sólo 13 pacientes cumplieron seguimiento postoperatorio a los 3 años. Se logró cuantificar la agudeza visual a los 3 años postoperatorios en 11 pacientes y 8 obtuvieron una clasifica ción de impedimento visual o peor. El 82.6% fueron consultas tardías (mayores a 3 meses de edad). Conclusiones: El diagnóstico de catarata congénita y su tratamiento quirúrgico fueron tardíos en esta serie. El abandono del seguimiento posoperatorio es alto. El resultado visual a los 3 años postopera torios en su mayoría es de impedimento visual o peor.

Abstract: The functional visual outcome after cataract surgery is influenced by several factors such as the age at diagnosis and surgical treatment, as well as visual rehabilitation. Objective: to characterize congenital cataract patients and assess the postoperative visual outcome in an ophthalmological care center in Guatemala. Patients and Method: A cross-sectional retrospective study. Clinical records of all congenital cataract patients who underwent congenital cataract surgery from 2014 and 2015 were reviewed. The following was recorded: postoperative visual acuity, age at diagnosis and surgery, sex, unilateral or bilateral involvement, etiology and morphology of the cataract, preoperative poor visual prognosis factors, and postoperative follow-up. Results: Fifty-nine patients underwent pediatric cataract surgery in this period, ages ranging from 1 month to 13 years (median 48 months), and 23 were congenital (38.98%). Fourteen were male, 16 bilateral, and the mean age at diagnosis and surgery was 7 and 12 months, respectively. Only 13 patients completed 3 years of follow-up visits. Visual acuity was recorded at 3 years after surgery, observing in 11 patients and 8 patients visual impairment or worse, respectively. Delayed consultations occurred in 82.6% of the patients (older than 3 months of age). Conclusion: In this series, the diagnosis of congenital cataract and its surgical treatment were delayed, observing a high rate of patients unable to complete follow-up visits. The visual outcome at 3 years after congenital cataract surgery was mostly visual impairment or worse.

ABSTRACT Introduction: Lowe syndrome or oculocerebrorenal syndrome is a multisystemic disorder. It's a rare and uncommon disease. Objective: Show a typical clinical case, with controlled renal failure without dialytic method and that late in the adolescence is diagnosed with Lennox-Gastaut syndrome. Case presentation: 18-year-old male adolescent born of a risk-free pregnancy and cesarean delivery, with macrosomia. From birth, he had a perinatal diagnosis of congenital cataract and evolutionarily bilateral glaucoma with conservative treatment. From the first year of life he suffers from tubular acidosis and Fanconi syndrome with an evolution to chronic kidney disease. All of these were related to delayed psychomotor development, intellectual disability, stereotypies, obsessive-compulsive symptoms and depression. Lately, at 10 years old, epileptic seizures of various types with predominance of tonic ones during sleep and wakefulness began; they were frequent, with characteristic electroencephalogram of Lennox-Gastaut syndrome. He had interdisciplinary care and stable clinical evolution into adulthood. The molecular study of the mother and child DNA confirmed the c2224_2226 mutation of GTA (exon 19), valine deletion at position 742 of the X chromosome of OCRL 1, which ratifies Lowe syndrome. Conclusion: Lowe Syndrome is a multisystemic disorder, linked to the X chromosome and common in males. Clinically, it is characterized by ophthalmological, renal and neurological alterations.

RESUMEN Introducción: El síndrome de Lowe o síndrome oculocerebrorenal es un trastorno multisistémico. Es una enfermedad rara e infrecuente. Objetivo: Exponer un caso clínico típico, con fracaso renal controlado sin método dialítico y que de manera tardía en su adolescencia se diagnostica con síndrome de Lennox-Gastaut. Presentación caso: Adolescente masculino de 18 años nacido de un embarazo sin riesgo y parto por cesárea, macrofeto. Desde el nacimiento, con diagnóstico perinatal de catarata congénita y evolutivamente glaucoma bilateral con tratamiento conservador. A partir del primer año de vida padece de acidosis tubular y síndrome de Fanconi con evolución a una enfermedad renal crónica. Relacionado todo con retraso del desarrollo psicomotor, discapacidad intelectual, estereotipias, síntomas obsesivos compulsivos y depresión. De manera tardía, a los 10 años tuvo inicio de crisis epilépticas de varios tipos con predominio de las tónicas durante el sueño y en vigilia, frecuentes, con electroencefalograma característico de síndrome Lennox-Gastaut. Tuvo atención interdisciplinaria y evolución clínica estable hasta la edad adulta cumplida. El estudio molecular de ADN materno y del niño confirmaron la mutación c2224_2226 del GTA (exón 19), delección de valina en la posición 742 del cromosoma X del OCRL 1, que ratifica el síndrome de Lowe. Conclusiones: El Síndrome de Lowe, es un trastorno multisitémico, ligado al cromosoma X y frecuente en varones. Clínicamente se caracteriza por alteraciones oftalmológicas, renales y neurológicas.

RESUMO Objetivo: O objetivo deste estudo foi analisar a segurança do implante de lente intraocular primária em um grande número de olhos em crianças <24 meses. Métodos: Foram revisados os prontuários de pacientes com idade entre 5-24 meses, submetidos a implante primário de lente intraocular no saco capsular. Uma lente intraocular acrílica de três peças dobrável foi implantada pelo mesmo cirurgião usando uma única técnica cirúrgica. Pacientes que tiveram <1 ano de acompanhamento após a cirurgia foram excluídos. Os principais resultados incluíram medidas de acuidade visual, mudança miópica, complicações pós operatórias e cirurgias adicionais. Resultados: Foram analisados 68 pacientes (93 olhos). A média de idade dos pacientes no momento da cirurgia foi de 15,06 ± 6,19 (5 a 24) meses, e o equivalente esférico 1 mês após a cirurgia foi de 3,62 ± 2,32 D. Após 5,67 ± 3,10 anos, o equivalente esférico foi de -0,09 ± 3,22 D, e a acuidade visual corrigida à distância foi de 0,33 ± 0,33 e 0,64 ± 0,43 logMAR em casos bilaterais e casos unilaterais, respectivamente (p=0,000). A maior mudança míopica foi observado em bebês submetidos à cirurgia aos 5 e 6 meses de idade. As complicações mais frequentes incluíram opacificação do eixo visual e corectopia. Glaucoma e descolamento de retina não foram relatados. Conclusão: O implante primário de lente intraocular no saco capsular em crianças de 5-24 meses é seguro e está associado à baixas taxas de eventos adversos e cirurgias adicional.

ABSTRACT Purpose: The purpose of this study was to analyze the safety of primary intraocular lens implantation in a large number of eyes in children aged <24 months. Methods: The medical records of patients aged 5-24 months, who underwent primary intraocular lens implantation in the capsular bag, were reviewed. A foldable three-piece acrylic intraocular lens was implanted by the same surgeon using a single surgical technique. Patients who had <1 year of follow-up after the surgery were excluded. The main outcome measurements included visual acuity, myopic shift, follow-up complications, and additional surgeries. Results: Sixty-eight patients (93 eyes) were analyzed. The mean age of the patients at the time of surgery was 15.06 ± 6.19 months (range: 5-24 months), and the spherical equivalent 1 month after surgery was 3.62 ± 2.32 D. After 5.67 ± 3.10 years, the spherical equivalent was -0.09 ± 3.22 D, and the corrected distance visual acuity was 0.33 ± 0.33 and 0.64 ± 0.43 logMAR in bilateral and unilateral cases, respectively (p=0.000). The highest myopic shift was observed in infants who underwent surgery at ages 5 and 6 months. The most frequent complications included visual axis opacification and corectopia. Glaucoma and retinal detachment were not reported. Conclusion: Primary in-the-bag intraocular lens implantation in children aged 5-24 months is safe, and is associated with low rates of adverse events and additional surgery.

ABSTRACT The importance of early diagnosis of compressive lesions of the optic nerve is on the increase. Timely decompression of the optic nerve or the optic chiasm may bring about significant visual function improvement, whereas erroneous diagnosis may result in irreversible visual loss, neurological dysfunction or death. The causes of compression of the anterior visual pathway are incredibly varied. Meningiomas, pituitary tumors and aneurysms are the lesions most commonly identified as causes of compressive optic neuropathy without disc edema. A case is presented of a female 50-year-old patient undergoing congenital cataract surgery of her left eye without visual function improvement, alongside unspecific visual quality worsening. Visual psychophysical testing, automated campimetry and optical coherence tomography contributed findings suggestive of intracranial visual pathway compression. Magnetic resonance imaging of the brain and orbits was indicated to confirm the diagnostic suspicion. Cerebral angiography revealed the presence of an internal carotid artery aneurysm which was treated by endovascular procedure with satisfactory results.

RESUMEN El diagnóstico temprano de las lesiones compresivas del nervio óptico adquiere cada vez mayor importancia. La descompresión precoz de este o del quiasma puede resultar una mejora significativa de la función visual, mientras que el diagnóstico erróneo puede ocasionar pérdida visual irreversible, disfunción neurológica o la muerte. Las causas de la compresión de la vía visual anterior son increíblemente variadas. Los meningiomas, los tumores hipofisarios y los aneurismas son las lesiones comúnmente más identificadas como causa de neuropatía óptica compresiva sin edema del disco. Presentamos una paciente femenina de 50 años de edad, quien se sometió a la cirugía de catarata congénita del ojo izquierdo, sin mejoría de la función visual, a lo que se sumó el empeoramiento inespecífico de la calidad visual. La psicofísica visual, la campimetría automatizada y la tomografía de coherencia óptica aportaron hallazgos sugestivos de compresión de la vía visual intracraneal. Se indicó imagen por resonancia magnética de cráneo y órbitas para confirmar la sospecha diagnóstica. La angiografía cerebral demostró la presencia de un aneurisma de la arteria carótida interna, que se trató por vía endovascular con resultados satisfactorios.

Resumo Objetivo: Descrever manifestações clínicas e fenotípicas e o prognóstico visual de uma família com aniridia congênita (AC). Métodos: Trata-se de estudo transversal envolvendo 31 indivíduos (56 olhos), de uma mesma família com fenótipo de AC residindo no município de Água Branca, no sertão do estado de Alagoas, região nordeste do Brasil. Foram analisadas variáveis clínicas e fenotípicas. Para a análise, foi utilizada a estatística descritiva (frequência absoluta e relativa e medidas de tendência central e de dispersão) e inferencial (testes de Shapiro-Wilk e t Student). Considerou-se o intervalo de confiança de 95% e a significância de 5%. Resultados: Dos 31 indivíduos, 18 (58,1%) eram do sexo masculino, com média de idade de 27,45±17,49, sem diferença entre os sexos. Dos 56 olhos avaliados, 26 eram olhos direitos e 30 olhos esquerdos: 61,3% (n=19) apresentavam aniridia bilateral total; 25,8% (n=8) referiam perda total de percepção da luz em ambos os olhos. As anormalidades oculares mais prevalentes foram o nistagmo (n=27; 87,09%), catarata (n=20; 64,5%), estrabismo 14 (45,2%), alterações opacidades ou vascularização corneanas (n=13; 41,93%) e ectopia lentis (n=6; 19,4%). Os 13 indivíduos submetidos à tomografia de coerência óptica (OCT) retiniana apresentavam perda da depressão foveal, redução da espessura macular e redução da acuidade visual. Nove indivíduos foram submetidos a cirurgia de facoemulsificação. Conclusão: O estudo mostrou ampla variação fenotípica entre os indivíduos estudados, com pobre prognóstico visual. O estudo destaca a necessidade de estabelecer mecanismos de cuidado integral para as famílias com a doença.

Abstract Objective: We aimed to describe the clinical and phenotypic manifestations as well as the visual prognosis of a family with CA in Northeastern Brazil. Methods: This was a cross-sectional study involving 31 individuals (56 eyes) from the same family presenting CA phenotypes. The study population resided in the municipality of Água Branca, in the backlands of the state of Alagoas, Northeastern Brazil. The clinical and phenotypic variables were analyzed. For the analysis, descriptive statistics (absolute and relative frequency and measures of central tendency and dispersion) and inferential statistics (Shapiro–Wilk and Student's t tests) were used, with 95% confidence intervals and significance set at 5%. Results: Of the 31 individuals, 18 (58.1%) were male, with a mean age of 27.45 ± 17.49 years, with no difference between sexes. Of the 56 eyes evaluated, 26 and 30 were right and left eyes, respectively; 61.3% (n = 19) individuals had complete bilateral aniridia and 25.8% (n = 8) reported a total loss of light perception in both the eyes. The most prevalent ocular abnormalities were nystagmus (n = 27; 87.09%), cataract (n = 20; 64.5%), strabismus (n = 14; 45.2%), corneal changes such as opacities and/or vascularization (n = 13; 41.93%), and ectopia lentis (n = 6; 19.4%). Further, 13 individuals underwent retinal optical coherence tomography, six man and seven women aged 9–48 (mean, 30.15 ± 15.9) years. All patients presented absence of foveal depression as well as reduced macular thickness and visual acuity. Nine subjects underwent phacoemulsification. Conclusion: The study showed wide phenotypic variation among the studied individuals, with poor visual prognosis. The study highlights the need to establish comprehensive care mechanisms for families with the disease.

Abstract: Objective: To report the case of a newborn with congenital cataract, which is rare condition (from one to 15 cases per 10,000 newborns) and in many cases, there is a delay in diagnosis. Case presentation: 16-day-old female full-term newborn, with normal pregnancy. There was no relevant personal or family history. From the third day of life, her mother noticed “greater brightness” in her left eye. The only abnormality detected on physical examination was left pupillary hyporeflexia, in addition to an asymmetric red reflex sign and “centropupillary” opacity. A pediatric ophthalmologist confirmed the diagnosis of congenital cataract and removed it at three months of age. Although her subsequent evolution was satisfactory, she developed glaucoma. Conclusion: Congenital cataract is an eye problem that is difficult to diagnose, therefore knowledge and training are required for its detection. For its identification, the deliberate search for the red reflex in all newborns and infants is required.

Resumen: Objetivo: Dar a conocer el caso de una recién nacida (RN) con catarata congénita, lo cual es infrecuente (de uno a 15 casos por 10,000 RN), y en muchos casos el diagnóstico se retrasa. Presentación del caso: RN femenino de 16 días de edad, de término, producto de un embarazo normal. No hay antecedentes personales ni familiares relevantes. Su madre notó “mayor brillo” en su ojo izquierdo desde el tercer día de vida. A la exploración física, la única anormalidad detectada fue hiporreflexia pupilar izquierda, además de signo de reflejo rojo asimétrico y opacidad “centropupilar”. Oftalmología pediátrica confirmó diagnóstico de catarata congénita, la cual se extirpó a los tres meses de edad. Aunque su evolución posterior fue satisfactoria, desarrolló glaucoma. Conclusión: La catarata congénita es un problema ocular de difícil diagnóstico, por lo que se requiere conocimiento y capacitación para su detección; la búsqueda sistemática del reflejo rojo en todo RN y lactante puede ayudar a su identificación.

ABSTRACT Introduction: as a result of the high incidence of low vision, as well as its negative consequences in the biological, psychological and social spheres, the authors take into account the insufficiency of interdisciplinary studies that collect the psychosocial effects of intraocular surgery for the improvement of the patients. Case presentation: 20-year-old black male patient with a personal pathologic history of bilateral congenital cataract, horizontal nystagmus and low vision; family ophthalmologic-pathologic history of congenital cataract through the maternal line. He was referred from his health area to a low vision consultation for progressive deterioration of bilateral vision. Previously, during his childhood, the patient had been treated in low vision consultation at Ramon Pando Ferrer Cuban Institute of Ophthalmology, where he was rehabilitated, inserted in the Diagnostic and Orientation Center where he finished his primary studies, later the patient went on to regular education to complete basic secondary education. Conclusions: it can be a motivational facilitator that makes possible to direct the actions that lead to an in-depth study regarding the particularities of each of the cases.

RESUMEN Introducción: como resultado de la elevada incidencia de la baja visión, así como sus consecuencias negativas en la esfera biológica, psicológica y social, los autores tienen en cuenta la escasez de estudios interdisciplinares que recojan los efectos psicosociales de la cirugía intraocular para la mejoría de los pacientes. Presentación del caso: paciente masculino de 20 años de edad, de raza negra, con antecedentes patológicos personales de catarata congénita bilateral, nistagmo horizontal y baja visión; antecedentes patológicos familiares oftalmológicos de catarata congénita por la línea materna. Es remitido desde su área de salud a consulta de baja visión por deterioro progresivo de la visión bilateral. Anteriormente, durante su infancia, el paciente había sido atendido en consulta de baja visión en el Instituto Cubano de Oftalmología “Ramón Pando Ferrer” donde fue rehabilitado, se insertó en el Centro de diagnóstico y orientación donde terminó sus estudios primarios, más tarde el paciente pasó a la enseñanza regular para culminar la secundaria básica. Conclusiones: puede ser un facilitador motivador que hace posible dirigir las acciones que llevan a un estudio en profundidad con respecto a las particularidades de cada uno de los casos.

RESUMO Um caso raro de microcoria congênita bilateral associada à antimetropia em um homem de 47 anos de idade é descrito aqui. O paciente queixava-se de perda visual progressiva em seu olho direito nos últimos 5 anos. Um exame com lâmpada de fenda e biomicroscopia ultrassônica confirmaram microcoria congênita e catarata. A facoemulsificação foi realizada usando dispositivo de expansão iriana, e a cápsula anterior foi corada através da técnica “trypan down under”. Considerações pré-operatórias, abordagem cirúrgica e manejo pós-operatório são discutidos.

ABSTRACT A rare case of bilateral congenital microcoria associated with antimetropia in a 47-year-old man is here described. The patient presented with a chief complaint of progressive vision loss in his right eye over the past five years. A slit-lamp examination and ultrasound biomicroscopy confirmed congenital microcoria and cataracts. Phacoemulsification was performed using an iris expansion device and the anterior capsule was stained using the “trypan down under” technique. Preoperative considerations, the surgical approach, and postoperative management are discussed.

Abstract Objective: To describe the causes of blindness in the students of the school for blind children "Josefa Vergara" in Querétaro, Mexico; as well as identifying treatable causes in the studied population. Methodology: The study was conducted in the period from December 2017 to February 2018, at the school for blind children "Josefa Vergara" in Querétaro, Mexico. Thirty students participated. The patients were interviewed and examined by the authors. The results obtained in the study were analyzed with the SPSS™ software version 21. Results: The majority of subjects were blind 28 (93%). The most frequent causes of visual loss were retinopathy of prematurity in 11 patients (36.7%) and congenital cataract in 5 patients (16.6%). In a lower percentage, Leber’s congenital amaurosis was found in 2 patients (6.7%), congenital retinal detachment in 2 patients (6.7%), retinoblastoma in 2 patients (6.7%), optic nerve hypoplasia in 2 patients (6.7%), among others. 73% of the participants in the study had a treatable cause of blindness. Conclusions: The retina was the main anatomical site affected. The most common diagnosis was sequelae of retinopathy of prematurity. Most patients had treatment alternatives that could prevent blindness in early stages of their disease. It is necessary to implement and intensify measures in the Mexican health system for the prevention of blindness in the pediatric population.

RESUMO A aniridia é uma doença ocular congênita com grau variável de hipoplasia ou ausência do tecido da íris. É causada pela perda de função do gene PAX6 e pode ser uma anormalidade ocular isolada ou parte de uma síndrome. WAGRO refere-se a uma condição genética rara que leva ao tumor de Wilms, aniridia, anomalias geniturinárias, déficit intelectual e obesidade e é causada por uma deleção do braço curto do cromossomo 11 (11p), onde o gene PAX6 está localizado. Aqui, nós relatamos um menino de 8 anos de idade com aniridia, catarata polar e subluxação do cristalino, além de retardo neuropsicomotor e de fala. A avaliação cariotípica revelou uma deleção intersticial envolvendo a região 11p13-p14, confirmando o diagnóstico da síndrome WAGRO. Em casos de aniridia, um diagnóstico de síndrome de WAGRO deve ser considerado.

ABSTRACT Aniridia is a congenital eye disorder with a variable degree of hypoplasia or absence of iris tissue. It is caused by loss of function of the PAX6 gene and may be an isolated ocular abnormality or part of a syndrome. WAGRO refers to a rare genetic condition leading to Wilms tumor, aniridia, genitourinary anomalies, mental retardation, and obesity and is caused by a deletion of the short arm of chromosome 11 (11p), where the PAX6 gene is located. Here, we report on an 8-year-old boy with aniridia, polar cataract, and lens subluxation along with neuropsychomotor and speech delays. Karyotype evaluation showed an interstitial deletion including region 11p13-p14, confirming the diagnosis of WAGRO syndrome. In cases of aniridia, a diagnosis of WAGRO syndrome should be considered.

Abstract Pediatric glaucomas are a heterogenous group of eye diseases associated in some cases to genetic syndromes. The objective of this study is to identify the different etiologies of glaucoma in children and to describe medical and surgical treatments in these patients in a tertiary referral hospital. Patients and Methods: Retrospective, descriptive and transversal study. Medical records analysis of patients diagnosed with glaucoma from 2011 to 2015. Age at diagnosis, laterality, etiology, associated syndromes, medical and surgical treatment and follow-up were gathered. Results: We identified 77 patients. Average age at diagnosis was 2.27 years. There was no gender predilection. The most frequent etiology was primary congenital glaucoma (63%) followed by glaucoma secondary to cataract surgery (19%). Sixty percent of all cases were bilateral. All patients underwent examination under anesthesia. Sixty-two patients (80%) required surgical treatment. There were 15 systemic and genetic diseases associated with pediatric glaucoma. Only two thirds of all patients continued their follow-up. Conclusions: Pediatric glaucomas are a challenge for ophthalmologists because they comprise a complex group of eye diseases with a difficult clinical approach due to systemic and genetic abnormalities, delayed diagnosis and high frequency of surgical treatment along with lack of follow-up.

Resumen El glaucoma en edad pediátrica es un grupo diverso de enfermedades oculares que pueden estar asociadas a diferentes síndromes. El objetivo de este trabajo es identificar las diferentes causas de glaucoma, así como describir el tratamiento médico y quirúrgico de estos pacientes en un hospital de referencia de tercer nivel. Pacientes y métodos: Estudio retrospectivo, descriptivo y transversal, en el que se revisaron los expedientes de los pacientes con diagnóstico de glaucoma que acudieron del 2011 al 2015 al Servicio de Oftalmología en el Hospital Infantil de México. Se analizaron: edad de diagnóstico, lateralidad, etiología, síndromes asociados, tratamiento establecido y seguimiento. Resultados: Se identificaron 77 pacientes. El promedio de edad en el momento del diagnóstico fue de 2.27 años, y no hubo preferencia de género. La etiología más frecuente del glaucoma fue el congénito primario (63%), seguido del secundario a cirugía de catarata congénita (19%). El 60% de los casos eran bilaterales. Todos los pacientes requirieron exploración bajo anestesia. Requirieron tratamiento quirúrgico 62 pacientes (80%). Encontramos 15 enfermedades y síndromes asociados a los pacientes que presentaron glaucoma. Solo dos terceras partes de los pacientes continuaron su seguimiento oftalmológico en la consulta externa. Conclusiones: El glaucoma pediátrico representa un reto para el oftalmólogo debido a la complejidad en el abordaje clínico debido a la presencia de síndromes y enfermedades sistémicas asociadas, así como el diagnóstico tardío, la alta frecuencia de procedimientos quirúrgicos y la pérdida de seguimiento.

Abstract: Introduction: A low-vision (LV) rehabilitated child can receive comprehensive education. Objec tive: To study the profile of school children referred for evaluation to a rehabilitation project in a social assistance agency. Patients and Method: Descriptive cross-sectional study of beneficiaries evaluated between September 2015 and September 2016 in the National Board of School Assistan ce and Scholarships (JUNAEB). The referral diagnosis, monocular visual acuity (VA) with optical correction at far (Feinbloom chart) and close (Zeiss chart) distances were considered. They were classified according to VA and perimetry. Treatment success was considered if VA reaches > 0.4 at far and/or close distances with optical devices. Results: 278 students were assessed. 153 (55%) were men, 121 (43.5%) between the ages of 10 to 14. Bilateral congenital cataract, retinal dystrophies, high myopia, optic atrophy, and congenital nystagmus were the most frequent pathologies. 224 students (80.6%) received optical devices. 85 (37.9%) presented moderate LV and 63 (28.6%) severe LV; 122 (54.5%) presented normal perimetry, 68 (30.4%) tubular Visual Field (VF), 19 (8.5%) sectoral VF defects, and 15 (6.7%) central scotoma. 198 (88.4%) students achieved visual success at a far distance and all achieved visual success at a near distance. 48 (17.2%) students could not be rehabilitated due to a neuro-ophthalmological condition (41.7%), high refractive error (16.6%) or congenital glauco ma (10.4%).Six (2.2%) cases improved VA with a new optical correction. Conclusion: This success demonstrates the need to provide low vision aids to schoolchildren with LV. Our challenge is to maintain this program and to educate ophthalmologist for timely referral.

Resumen: Introducción: Un niño con baja visión (BV) rehabilitado puede tener una educación integral. Objetivo: Estudiar el perfil de los escolares derivados para evaluación a un Proyecto de Rehabilitación en un organismo de apoyo social. Pacientes y Método: Estudio transversal descriptivo de beneficiarios evaluados entre septiembre 2015 y septiembre 2016 en JUNAEB. Se consideró diagnóstico de derivación, agudeza visual monocular (AV) con corrección óptica para lejos (cartillas Feinbloom) y cerca (cartillas Zeiss). Se clasificaron según AV y perimetría. Se consideró éxito de tratamiento lograr AV > 0,4 para le jos y/o cerca con ayuda óptica. Resultados: Se evaluaron 278 escolares. 153 (55%) fueron hombres, 121(43,5%) entre 10 a 14 años. Catarata congénita bilateral, distrofias retinales, alta miopía, atrofia óptica y nistagmus congénito fueron las patologías más frecuentes. 224 (80,6%) se habilitaron con ayudas. 85 (37,9%) presentaron BV moderada y 63 (28,6%) BV severa. 122 (54,5%) presentaban perimetría normal, 68 (30,4%) campo visual (CV) tubular, 19 (8,5%) defecto sectorial del CV y 15 (6,7%) compromiso central del CV. 198 (88,4%) escolares lograron éxito visual de lejos y todos lograron éxito visual de cerca. 48 (17,2%) escolares no pudieron ser rehabilitados, estando asocia dos a una afección neuroftalmológica (41,7%), alto error refractivo (16,6%) o glaucoma congénito (10,4%). 6 (2,2%) casos mejoraron su AV con nueva corrección óptica. Conclusión: El éxito obteni do demuestra la necesidad de habilitar visualmente a escolares con BV. Nuestro desafío es mantener este programa y educar al oftalmólogo prestador para una derivación oportuna.

Introduction: congenital and infant cataracts are a threat for children visual development because this can mainly be inhibited or stopped and it also requires a complicated treatment. Objective: to evaluate anatomic and visual results of infant cataracts surgeries by self-sealant corneal incision. Method: a transversal study which universe was composed by 19 children (24 eyes) suffering from congenital or infants cataracts, who were operated at the Pediatric Hospital of Holguín, during 2016 to 2017, was carried out. Some variables like: age, sex, etiology, pre and postsurgical visual sharpness in the first 3 months, surgical techniques, induced astigmatism, transparency preservation corneal curve and possible complications, were evaluated. Results: ages from 3 to 8 years prevailed up to 47.4%, as well as males with 79% and congenital etiology with a 50%. Pre-surgical visual sharpness was in the range of PL- 0.1 representing the 50%, while post- surgical was between 0.7- 1.0 in 62.5% of the cases. Surgical technique was the self-sealant small incision in 75%. Induced astigmatism was low, less than 1D. Corneal transparency was obtained 100%, and the corneal curvature had minor variations (≤0.50D) in 62.5% of the cases. Most frequent complications were posterior capsule dullness (50%) and the anterior uveitis (37.5%). Conclusions: the use of the small self-sealant corneal incision in the infant cataracts surgery guarantees good anatomic and visual outcomes.

Introducción: las cataratas congénitas e infantiles constituyen una amenaza para el desarrollo visual en los niños, pues inhiben o detienen potencialmente su maduración, unido a la complejidad de su tratamiento. Objetivo: evaluar los resultados visuales y anatómicos de la cirugía de catarata infantil con el uso de la incisión corneal pequeña autosellante. Método: se realizó un estudio transversal, cuyo universo estuvo constituido por 19 niños (24 ojos) con catarata congénita e infantil, intervenidos quirúrgicamente en el Hospital Pediátrico de Holguín en 2016 y 2017. Se evaluaron las variables: edad, sexo, etiología, agudeza visual pre y postoperatoria a los 3 meses, técnica quirúrgica empleada, astigmatismo inducido, conservación de la transparencia y curvatura corneal, así como complicaciones. Resultados: predominó el grupo de edad de 3 a 8 años con el 47,4%, y el sexo masculino, con el 79%, y la etiología congénita ascendió hasta el 50%. La agudeza visual preoperatoria entre percepción luminosa a 0,1 se presentó en el 50%. En la postoperatoria del 62,5% de los casos se obtuvo entre 0,7 a 1,0. La técnica quirúrgica empleada fue la incisión corneal pequeña autosellante, en el 75%, y el astigmatismo inducido fue bajo, menor de 1 D. La transparencia corneal se conservó en el 100%, y en el 62,5% la curvatura corneal tuvo variaciones mínimas (≤0,50 D). Las complicaciones más frecuentes fueron opacidad de la cápsula posterior con 50% y uveítis anterior con el 37,5%. Conclusiones: el uso de la incisión corneal pequeña autosellante en la cirugía de catarata infantil garantiza buenos resultados visuales y anatómicos.
