The pseudoxanthoma elasticum is a generalized disease of the connective tissue involving the skin, eyes and cardiovascular system triggering the fragmentation and calcification of elastic fibers. Usually occurs after puberty, the manifestations characteristics are small spots, circumscribed, yellowish, located on the neck, axilla and inguinal folds. Angioid streaks in the retina, tendency to hemorrhage and arterial insufficiency are the most common complications. This disease can be inherited as autosomal dominant or recessive. The treatment of ocular manifestations is through the […]

Particle Swarm Optimization (PSO) is an artificial intelligence technique (AI) that can be used to find approximate solutions to numerical problems of maximization and minimization. In this study, it was used a PSO algorithm to compare displacements from human cornea sample subjected to internal pressure of 45 mmHg with Results of numerical simulations were provided which identified optimized values for hyperelastic properties of the cornea (µ and α). By means of the results from numerical simulations via inverse analysis by […]

Objective: To evaluate the self-esteem and quality-of-life outcomes in patients undergoing upper blepharoplasty. Methods: A cross-sectional study was performed at Federal University of São Paulo. The self-esteem and quality-of-life of 29 patients undergoing upper blepharoplasty were compared with 20 age-matched volunteers from the general population. During preoperative assessment, the patients and volunteers underwent complete ophthalmological examinations and answered two questionnaires: the Rosenberg self-esteem scale (RSES) and the World Health Organization quality of life assessment (WHOQOL-BREF). The RSES is a ten-item […]

Objetivo: Avaliar os resultados de autoestima e qualidade de vida em pacientes submetidos à blefaroplastia superior. Métodos: Um estudo transversal foi realizado na Universidade Federal de São Paulo. A autoestima e a qualidade de vida de 29 pacientes submetidos à blefaroplastia superior foram comparadas com 20 voluntários pareados para idade. Durante a avaliação pré-operatória, os pacientes e voluntários foram submetidos a exames oftalmológicos completos e responderam a dois questionários: a escala de autoestima de Rosenberg (RSES) e a avaliação da […]

Objective: To determine the influence of visual field results in the diagnosis of glaucoma. Methods: A questionnaire with ophthalmologists was conducted where slides of a digital photograph of the optic disc and computerized visual field exam were presented.(Physicians were instructed to answer whether glaucoma was observed in each of the slides). No other information was given to those examiners. Half of the patients had glaucoma with corresponding visual field, and the other half had physiological cupping and normal visual field. […]

Objetivo: Avaliar a influência da campimetria computadorizada no diagnóstico do glaucoma. Métodos: Foi realizado questionário com oftalmologistas apresentando slides com uma fotografia digital de disco óptico e campo visual computadorizado. Os médicos deveriam assinalar se o exames apresentados eram de glaucoma ou não. Nenhuma outra informação foi passada para os examinadores. Metade dos pacientes apresentavam glaucoma com dano correspondente de campo visual, e a outra metade aumento fisiológico da escavação e campo visual normal. Os slides foram igualmente divididos em: […]

Objective: To study, through histopathological examination, calcium deposits in the cornea and its different presentation forms. Methods: Observational, transversal, retrospective and descriptive study of corneal buttons from penetrating keratoplasty from 2006 to 2015. Routine staining was performed with Hematoxylin-eosin, and in some cases additional staining was performed: Masson, PAS (Periodic Acid Of Schiff reaction) and reticulin. The tissues were examined with an optical microscope by the authors. We selected only the cases in which calcium deposits were identified in the […]

Purpose: To characterize the population of diabetics referred to the Ophthalmology Department of the Centro Hospitalar do Porto (CHP) from the screening program of ARS Norte, to evaluate this type of screening method and to perceive the its impact in the dynamic of an Ophthalmology Department. Methods: Retrospective evaluation of the clinical processes of diabetic patients referred to the CHP Diabetic Retinopathy (DR) Screening Consultation from the ARS Norte screening program, between January 2012 and December 2016. The variables analyzed […]
