RESUMEN

Capsular block syndrome is a rare complication of phacoemulsification surgery with continuous curvilinear capsulorhexis and intraocular lens implantation. Here, we report a case of very late-onset capsular block syndrome that developed 13 years after cataract extraction and present the surgical approach used for its successful treatment.

RESUMEN

PURPOSE: High intraocular pressure (IOP) is an important risk factor for a variety of pediatric ophthalmic conditions. The purpose of this study is to evaluate the feasibility, length of examination, and corneal epithelial damage induced by rebound tonometry (RBT) versus Goldmann applanation tonometry (GAT) in school children. METHODS: Healthy children (n=57) participated in a randomized, transversal study with IOP measurement by GAT followed by RBT (study arm 1) or RBT followed by GAT (study arm 2). The number of attempts to acquire a reliable IOP measurement and the length of the examination were quantified. Corneal epithelial damage induced by tonometry was evaluated. Bland-Altman analysis was performed to establish the level of agreement between the two techniques. RESULTS: The IOP was measured in all children with at least one of the devices. In both study arms, more children failed to be examined with GAT than with RBT (26% vs. 4%, and 16% vs. 6%, p<0.001, in study arm 1 and 2, respectively). The length of examination was shorter for RBT than for GAT (67.81 s ± 35.20 s vs. 126.70 s ± 56.60 s; p<0.0001); IOP measurements with RBT in both study arms were higher than those with GAT (15.20 ± 2.74 mmHg vs. 13.25 ± 2.47 mmHg, p=0.0247 and 16.76 ± 3.99 mmHg vs. 13.92 ± 2.08 mmHg, p=0.003, respectively). No difference was observed between RBT and GAT regarding the corneal epithelial damage caused by tonometry. CONCLUSION: IOP measurement is feasible in a greater number of children with RBT, and the examination was faster than that for GAT. Compared with GAT, RBT tended to overestimate the IOP. None of the methods induced marked corneal epithelial defects.

RESUMEN

PURPOSE: To investigate the seasonality of infectious keratitis in a tertiary hospital in Brazil. METHODS: Charts from the Ocular Microbiology Laboratory of the Department of Ophthalmology of the Federal University of Sao Paulo were reviewed from 2005 to 2009. Infectious keratitis were defined as those with positive culture. Data were distributed monthly and linear regressions with seasonal dummy models were used to test for seasonal trends. RESULTS: Total of 1,468 cases of keratitis was diagnosed during the study period. Bacterial keratitis were responsible for 80.3% of all cases, followed by fungal (7%), and Acanthamoeba (6%); 6.7% were mixed cases. Statistical tests showed that there were no seasonal trends for bacteria (p=0.064), fungi (p=0.379), Acanthamoeba (p=0.062) or mixed infections (p=0.441). CONCLUSIONS: No seasonal trends for infectious keratitis were observed in our sample.

The number of attempts to acquire a reliable IOP measurement and the length of the examination were quantified. Corneal epithelial damage induced by tonometry was evaluated.

RESUMO Objetivo: A pressão intraocular (PIO) elevada é um importante fator de risco presente em diversas patologias que acometem crianças. O objetivo deste estudo é avaliar a viabilidade, a duração do exame e o dano epitelial corneano induzido pela tonometria de rebote (RBT) versus a tonometria de aplanação de Goldmann (GAT) em crianças em idade escolar. Métodos: Crianças sem comorbidades (n=57) participaram de um estudo randomizado e transversal com medidas da pressão intraocular com GAT seguido de RBT (sequência 1) ou RBT seguido de GAT (sequência 2). O número de tentativas para adquirir uma medição confiável da pressão intraocular e a duração de exame foi quantificado. Danos epiteliais induzidos pela tonometria foram avaliados. Análise de Bland-Altman foi realizada para estabelecer a concordância entre as duas técnicas. Resultados: A pressão intraocular foi medida em todas as crianças com pelo menos com um dos dispositivos. Em ambas as sequências do estudo, mais crianças não permitiram o exame com GAT (26% vs. 4% e 16% vs. 6%, p<0,001). A duração exame com RBT foi menor (67,81 ± 35,20 s vs. 126,70 ± 56,60 s; p<0,0001). As medições de pressão intraocular com este tonômetro em ambas as sequências do estudo foram mais elevadas do que as medidas adquiridas com GAT (15,20 ± 2,74 mmHg vs 13,25 ± 2,47 mmHg, p=0,0247 e 16,76 ± 3,99 mmHg vs. 13,92 ± 2,08 mmHg; p=0,003, respectivamente). Não foi observada diferença quanto à lesão epitelial corneana induzida pela tonometria com RBT e GAT. Conclusão: A medição da pressão intraocular foi possível em um maior número de crianças com a tonometria de rebote, além de ser um exame mais rápido do que GAT. A pressão intraocular foi superestimada com RBT em comparação com GAT. Nenhum dos métodos induziu defeito epitelial corneano significativo.

RESUMEN

OBJETIVO: Investigar sazonalidade de ceratities infecciosas em serviço terciário no Brasil. MÉTODOS: Estudo retrospectivo de dados coletados do Laboratório de Microbiologia Ocular do Departamento de Oftalmologia da Universidade Federal de São Paulo de 2005 a 2009. Foram definidas como ceratites infecciosas aquelas com cultura positiva para o agente. Dados foram distribuídos de acordo com os meses do ano e modelos de regressão linear com variáveis "dummy" foram utilizados para testar sazonalidade. RESULTADOS: Foram diagnosticados 1.468 casos de ceratite infecciosa durante o período do estudo. Bactérias foram responsáveis por 80,3% dos casos seguidas por fungos (7%), Acanthamoeba (6%) e casos mistos (6,7%). Testes estatísticos não mostraram sazonalidade para bactérias (p=0,064), fungos (p=0,379), Acanthamoeba (p=0,062) ou casos mistos (p=0,441). CONCLUSÃO: Não foi observada sazonalidade nas ceratites infecciosas em nossa amostra.

Infectious keratitis were defined as those with positive culture. Data were distributed monthly and linear regressions with seasonal dummy models were used to test for seasonal trends. RESULTS: Total of 1,468 cases of keratitis was diagnosed during the study period. Bacterial keratitis were reponsible for 80.3% of all cases, followed by fungal (7%), and Acanthamoeba (6%); 6.7% were mixed cases. Statistical tests showed that there were no seasonal trends for bacteria (p=0.064), fungi (p=0.379), Acanthamoeba (p=0.062) or mixed infections (p=0.441). Conclusions: No seasonal trends for infectious keratitis were observed in our sample.
