Utilidade da estesiometria corneal na triagem da retinopatia diabética
OBJECTIVE: To assess the usefulness of corneal esthesiometry for screening diabetic retinopathy. METHODS: A cross-sectional study was carried out comprising 575 patients attending a diabetic retinopathy-screening program in the city of SĂŁo Paulo. Corneal esthesiometry was assessed with the Cochet-Bonnet esthesiometer. The presence of diabetic retinopathy was detected with indirect fundoscopy. The validity of corneal esthesiometry in identifying diabetic retinopathy was evaluated by the Receiver Operating Characteristic (ROC) curve. RESULTS: Sensitivity and specificity analyses of the corneal esthesiometry for detecting the stages of diabetic retinopathy using different cut-offs showed values less than 80%. The best indices (72.2% sensitivity and 57.4% specificity) were obtained for the identification of patients with proliferative diabetic retinopathy. CONCLUSIONS: In the study series, corneal esthesiometry was not a good indicator of diabetic retinopathy.OBJETIVO: Avaliar a utilidade da estesiometria corneal na triagem da retinopatia diabĂ©tica. MĂTODOS: Foi realizado um estudo transversal (N=575) em um programa de triagem de retinopatia diabĂ©tica da Cidade de SĂŁo Paulo, SP. A sensibilidade corneal foi aferida utilizando-se o estesiĂŽmetro de Cochet-Bonnet. A avaliação da retinopatia diabĂ©tica foi obtida por meio da fundoscopia indireta. A validade do uso da estesiometria corneal na identificação de pacientes com retinopatia diabĂ©tica foi avaliada por meio de curvas de sensibilidade e especificidade (Receiver Operating Characteristics (ROC) curve). RESULTADOS: A anĂĄlise da sensibilidade e da especificidade da estesiometria corneal na detecção dos diferentes graus de retinopatia, utilizando-se diferentes pontos de corte, mostrou resultados inferiores a 80%. O melhor resultado obtido ocorreu na identificação de pacientes com retinopatia diabĂ©tica proliferativa, mostrando sensibilidade de 72,2% e especificidade de 57,4%. CONCLUSĂES: Na sĂ©rie analisada, a estesiometria corneal nĂŁo se mostrou um bom indicador da presença da retinopatia diabĂ©tica.Universidade Federal de SĂŁo Paulo (UNIFESP) Departamento de OftalmologiaUNIFESP, Depto. de OftalmologiaSciEL

Application of Anterior Segment Optical Coherence Tomography in Pediatric Ophthalmology
Purpose. Application of anterior segment optical coherence (AS-OCT) in pediatric ophthalmology.
Methods. Retrospective clinical study case series of 26 eyes of 19 pediatric patients throughout a 21-month period, presenting anterior segment pathologies, were submitted to AS-OCT examination (OCT Visante, 1310ânm, Zeiss), noncontact technique, no sedation requirement. Results. AS-OCT images were obtained from 19 patients (range: 2 months to 12 years). Clinical diagnosis of anterior segment abnormalities included cornea disease (n=7), congenital anterior segment conditions (n=10), ocular trauma (n=1), anterior segment surgeries (n=2), iridocorneal angle abnormalities (n=4), intermediate uveitis (n=2). The most common OCT findings were corneal hyperreflectivity and thickening (n=15), shallow anterior chamber with iris-lens diaphragm anterior displacement (n=4), atypical corneal curvature (n=4), corneal thinning (n=4), peripheral synechiae with angle closure (n=3), increased anterior chamber depth (n=2), and proximal portion of glaucoma drainage tube (n=2). Conclusion. In the present study, noncontact AS-OCT demonstrated to be a feasible technique to evaluate the anterior segment providing anatomic details and useful to clarify diagnosis in the pediatric population
