Objetivo: Descrever o perfil epidemiológico de pacientes na fila de transplante de córnea no estado de Pernambuco, Brasil. Métodos: Estudo transversal e retrospectivo realizado no período 01/06/2011 a 31/05/2012, com 871 pacientes cadastrados na fila de espera para transplante de córnea na Central de Notificação, Captação e Distribuição de Órgãos de Pernambuco (CNCDO/PE). Os dados foram coletados por meio de protocolos baseados nas fichas de cadastro de receptor de córnea. Resultados: Em relação à frequência, obteve-se 54% do gênero feminino, 35% na faixa etária de 61 a 80 anos; 60% transplantados; 52% provenientes da região Metropolitana do Recife; 57% que aguardaram 1 a 6 meses o transplante; 82% com indicação de transplante óptico; 5% com prioridade na fila de espera (destes 48% por perfuração ocular) e 37% cujo centro transplantador era a Fundação Altino Ventura (FAV). As principais indicações para transplante de córnea foram leucoma (33%), ceratocone (22%) e ceratopatia bolhosa (18%). Conclusão: Verificou-se que a maioria dos pacientes encontra-se na faixa etária de 61 a 80 anos; era da Mesorregião Metropolitana de Recife; foi submetida ao transplante de córnea; aguardou de um a seis meses para realizar o transplante; teve como diagnóstico o leucoma, seguido por ceratocone e ceratopatia bolhosa; teve como indicação o transplante óptico e teve como centro transplantador a FAV.

Purpose: To describe the epidemiological profile of patients waiting for penetrating keratoplasty in state of Pernambuco, Brazil. Methods: Transversal and retrospective study, with 871 patients, in the period of 06/01/2011 a 05/31/2012, were registered on the waiting list for corneal transplantation in the Central of Notification, Captation and Distribution of Organs (CNCDO) of Pernambuco. Registration forms of cornea receiving were used, adapted to the purposes of this research. Results: In relation to frequency, it was obtained 54% female, 35% aged 61 to 80 years; 60% transplanted; 52% from the metropolitan area of Recife; 57% that waited 1 to 6 months the transplant; 82% with optical indication for transplant, 5% with priority on the waiting list (48% of those with ocular perforation) and; 37% whose transplant center was the Fundação Altino Ventura (FAV). The main indications for corneal transplantation were leukoma (33%), keratoconus (22%) e bullous keratopathy (18%). Conclusion: It was found that most patients were aged 61 to 80 years; was from the metropolitan area of Recife; was submitted to corneal transplantation; waited for one to six months to do the transplantation; had the diagnosis leukoma, followed by keratoconus and bullous keratopathy; was indicated to transplantation optical and had the transplant center to FAV.

OBJETIVO: Comparar critérios de indicação, complicações intra e pós-operatórias, resultados visuais obtidos e intervalo de tempo entre cirurgias do primeiro e segundo olho submetidos a facoemulsificação durante curva de aprendizado de um cirurgião. MÉTODOS: Estudo prospectivo de 96 olhos de pacientes submetidos à cirurgia de catarata bilateral, pela técnica de facoemulsificação, no período de abril/2001 a março/2002, de forma consecutiva, por residente do terceiro ano. A mesma técnica cirúrgica foi realizada em todos pacientes. Na análise estatística foram utilizados os testes: qui-quadrado, Mann-Whitney, Kruskal-Wallis, comparações múltiplas de Dunn e t de Student. Todos foram bicaudais e considerados significantes quando p<0,05. RESULTADOS: A indicação cirúrgica foi realizada mais precocemente no segundo olho (melhor acuidade visual) (p=0,016). O tempo médio de facoemulsificação do primeiro olho operado foi significantemente maior que o do segundo olho (p=0,026). Não houve diferença estatisticamente significante entre os grupos em relação ao grau de catarata, doença ocular prévia, acuidade visual final e equivalente esférico médio. As complicações intra e pós-operatórias apresentaram incidências menores no segundo olho, apesar de não alcançar significância estatística (p=0,07). O intervalo de tempo entre a cirurgia do primeiro e segundo olho foi significativamente menor ao longo dos trimestres (p<0,001). CONCLUSÕES: Ao longo dos trimestres, os pacientes foram submetidos à cirurgia do segundo olho mais precocemente (melhor acuidade visual e menor intervalo de tempo entre as cirurgias), apresentaram tempo de facoemulsificação menor e tendência a terem menores complicações intra e pós-operatórias.

PURPOSE: To compare indication criteria, intra- and postoperative complications, visual outcomes and time interval between the first and second eye surgery (phacoemulsification). METHODS: Prospective study was done in 96 eyes of patients who underwent bilateral consecutive phacoemulsification surgery, performed by a third-year ophthalmology resident. An established protocol was filled out before, during and after the surgery. The same surgical technique was used. Chi-squared, Mann-Whitney, Kruskal-Wallis, Dunn multiple comparison and Student's t tests were used for statistical analysis. Bicaudal tests were used in all situations. p<0.05 rejected the null hypothesis. RESULTS: The indication for the second eye surgery was done earlier and with best correct visual acuity when compared with the first eye (p=0.016). The mean phacoemulsification ultrasound time (US time) of the first eye was significantly higher (p=0.026). There were no statistically significant differences between the two groups in relation to type of cataract, previous intraocular diseases, final visual acuity and mean spherical equivalent. The incidence of intra- and postoperative complications was smaller in the second eye, but was not statistically significant (p=0.07). Time interval between the first and second eye surgery was significantly lower along the trimesters. CONCLUSION: The patients underwent the second eye phacoemulsification surgery earlier (with better visual acuity and shorter time interval), had a shorter phacoemulsification time and tendency to be followed by less intra- and postoperative complications.

Schistosoma mansoni is responsible for lesions that can alter the hemodinamic of the portal venous circulation, lung arterial and venous sistemic systems. Therefore, hemodinamic changes in the ocular circulation of mansonic schistosomotic patients with portal hypertension and hepatofugal venous blood flow is also probable. The purpose of this study was to determine the fluorescein contrast arrival time at the retina of young patients with the hepatosplenic form of schistosomiasis, clinically and surgically treated. The control group included 36 non schistosomotic patients, mean age of 17.3 years, and the case group was represented by 25 schistosomotic patients, mean age of 18.2 years, who were cared for at The University Hospital (Federal University of Pernambuco, Brazil), from 1990 to 2001. They underwent digital angiofluoresceinography and were evaluated for the contrast arrival time at the early retinal venous phase of the exam. Both groups were ophthalmologically examined at the same hospital (Altino Ventura Foundation, Recife, Brazil), using the same technique. There was retardation of the retinal contrast arrival time equal or more than 70 sec in the eyes of three schistosomotic patients (12%) and in none of the control group, however, the mean contrast arrival time between the two groups were not statistically different. These findings lend support to the hypothesis that there could be a delay of the eye venous blood flow drainage.
