ABSTRACT Objective: To develop and examine the usability of a mobile application aimed at improving knowledge about ocular surface tumors among medical students, general practitioners and ophthalmologists. Methods: A cross-sectional quantitative study was carried out by a multidisciplinary team and developed in three stages: administration of a specific questionnaire to medical students, assessing the demand for the application, creation and development of the application in collaboration with the Technological Innovation Laboratory of Centro Universitário Christus and usability assessment. General practitioners and ophthalmologists were selected to answer the System Usability Scale questionnaire. Data were exported into the Statistical Package for the Social Sciences, version 20.0 Windows, for quantitative analysis. Results: The OncoEye application was developed for the iOS and the Android platforms and included four main menus: Glossary, Patients, Referrals and Queries. Most students (89.9%) considered the development of the application important for wider access to information about the topic. Most students (39.9%) were able to recognize ocular lesions and 26.1% could distinguish between benign and malignant conditions. System Usability Scale questionnaire responses revealed good usability, with an average score of 92.65. Users (100%) described the application as user-friendly and well- integrated. Conclusion: An innovative application for ocular surface tumors was created and developed. The application achieved good levels of acceptance and was described as user-friendly by users.

RESUMO Objetivo: Avaliar os óbitos causados por câncer ocular durante os anos de 2010 a 2019 no Brasil. Métodos: Os dados foram selecionados na plataforma do Departamento de Informática do SUS do Ministério da Saúde, incluindo declarações de óbito, durante os anos de 2010 a 2019, de todos os estados brasileiros e do Distrito Federal, filtrando os códigos C69.0 a C69.9 como causa básica de óbito, de acordo com a Classificação Internacional de Doenças e Problemas Relacionados à Saúde – 10ᵃ Revisão. Resultados: Houve 1.859 óbitos por neoplasia maligna de olho e anexos (C69), no Brasil, no período de 2010 a 2019, acometendo 1.062 (57,1%) homens. O sítio da neoplasia não foi especificado (C69.9) em 719 casos, representando a etiologia mais frequente no grupo C69 (38,67%). A neoplasia maligna da órbita (C69.6) foi a segunda causa mais comum de óbito (22,59%), seguida pela neoplasia maligna da retina (C69.2) (14,73%). Conclusão: O número de óbitos por neoplasia maligna de olho e anexos aumentou discretamente ao longo dos anos de 2010 a 2019, no Brasil.

ABSTRACT Objective: To assess the deaths caused by eye cancer from 2010 to 2019 in Brazil. Methods: Data were selected from SUS’ Computer Department platform at the Ministry of Health, including death certificates, from 2010 to 2019, from all Brazilian states and the Federal District, filtering the codes C69.0 to C69.9 as the cause of death, according to the International Classification of Diseases, Tenth Revision. Results: There were 1,859 deaths from malignant neoplasm of eye and adnexa (C69), in Brazil, from 2010 to 2019, affecting 1,062 (57.1%) men. The site of neoplasm was unspecified (C69.9) in 719 cases, representing the most frequent etiology in the C69 group (38.67%). The malignant neoplasm of the orbit (C69.6) was the second most common cause of death (22.59%), followed by malignant neoplasm of retina (C69.2) (14.73%). Conclusion: The number of deaths due to malignant neoplasm of eye and adnexa slightly increased through the years of 2010 to 2019, in Brazil.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the effects of the COVID-19 pandemic and the social isolation on the interest rates of different medical specialties in Brazil. METHODS: The research was performed using the terms “Médico” (Doctor), “Infectologista” (Infectologist), “Cirurgião” (Surgeon), “Geriatra” (Geriatrician), “Otorrinolaringologista” (Otolaryngologist), and “Oftalmologista” (Ophthalmologist), related to several medical specialties, and “COVID-19,” which represented the public interest for the disease, utilizing the Brazilian version of Google Trends, where the data were acquired. The time range of this analysis was from 29 September, 2019 to 20 September, 2020. The data were tabulated in Microsoft Excel, exported to the Statistical Package for the Social Sciences software, and correlated with searches for the term “COVID-19” using Pearson's correlation. 95% confidence interval was used for all analyses. RESULTS: “Geriatra” (72.26±16.42) and “Cirurgião” (72.15±12.53) remained with the higher means among the evaluated specialties. In terms of standard deviation, “Oftalmologista” (64.71±16.72) and “Infectologista” (22.03±16.60) presented the most significant changes. After utilizing the Pearson's analysis to identify the correlation between each medical specialty and the term “COVID-19,” all the evaluated specialties presented significant statistical correlations. “Oftalmologista” (r= -0.607) was notoriously the most negatively affected, while “Infectologista” (r=0.504) was pointed to have the highest positive correlation with the term. CONCLUSIONS: Several changes in the interest rates of different medical specialties in Brazil were found during the time range of the COVID-19 pandemic.

Resumo Objetivo: Traçar o perfil epidemiológico do tratamento clínico para o glaucoma no Brasil fornecido pelo Sistema Único de Saúde (SUS), no período de janeiro de 2012 a dezembro de 2018. Métodos: Estudo quantitativo e descritivo, utilizando a base de dados disponível no Sistema de Informações Ambulatoriais do SUS (SIA/SUS). As variáveis utilizadas foram: tratamento monocular com drogas de primeira, de segunda e de terceira linha; tratamento monocular com combinações de duas drogas e de três drogas de diferentes linhas; tratamento binocular com drogas de primeira, de segunda e de terceira linha; e tratamento binocular com combinações de duas drogas e de três drogas de diferentes linhas. Resultados: Durante o período analisado, a prevalência de terapias clínicas para o glaucoma aumentou entre 2012 e 2017 e diminuiu entre 2017 e 2018. Dos pacientes tratados clinicamente, 96% eram portadores de glaucoma binocular. Entre as regiões do Brasil, o Nordeste teve a maior prevalência de glaucoma binocular (cerca de 60% do número de casos), e a terapia mais comum foi a combinação de duas drogas de diferentes linhas. A região Sudeste teve a maior concentração de glaucoma monocular (53% dos casos), e a terapia predominante foi a combinação de três drogas de diferentes linhas. A região Centro-Oeste apresentou a menor prevalência de tratamentos monoculares para o glaucoma (menos de 6%). Conclusão: No Brasil, o maior número de tratamentos oferecidos pelo sistema público de saúde foi nas regiões Nordeste e Sudeste. Existe uma alta prevalência nacional e um alto potencial para morbidade desta doença. Portanto, é necessário fortalecer programas voltados para o diagnóstico precoce e para o tratamento adequado a fim de reduzir os resultados adversos.

Abstract Purpose: To outline the epidemiological profile of clinical treatments for glaucoma provided by the Brazilian Unified Health System (SUS, acronym in Portuguese) between January 2012 and December 2018. Methods: A quantitative and descriptive study was conducted using available data based on the outpatient information system from SUS (SIA/SUS, acronym in Portuguese). The variables were monocular treatment with first, second, and third-line drugs; monocular treatment with combinations of two drugs and three drugs from different lines; binocular treatment with first, second, and third-line drugs; and binocular treatment with combinations of two drugs and three drugs from different lines. Results: During the analysis period, the prevalence of clinical therapies for glaucoma increased from 2012 to 2017 and decreased from 2017 to 2018. Of the clinically treated patients, 96% were carriers of binocular glaucoma. Among the regions of Brazil, the Northeast had the highest prevalence of binocular glaucoma (about 60% of the number of cases), and the most common therapy was combinations of two drugs from different lines. The Southeast region had the highest concentration of monocular glaucoma (53% of cases), and the predominant therapy was combinations of three drugs from different lines. The Midwest region had the lowest prevalence of monocular-treatments for glaucoma (less than 6%). Conclusion: In Brazil, the highest number of treatments offered by the public health system was in the Northeast and Southeast regions. There is a high national prevalence and potential for the morbidity of this disease. Therefore, it is necessary to strengthen programs aimed at early diagnosis and appropriate treatment to reduce adverse outcomes.
