PURPOSE: To evaluate the ocular condition in a brazilian ironmaster industry. METHOD: A prospective study was conducted in 2516 employees from an ironmaster brazilian industry in São Paulo city, Brazil. A questionnaire was applied and visual acuity and Ishihara test were performed in every individual. A complete ophthalmic evaluation (slit lamp examination, fundoscopy, tonometry and refractometry) was done when the visual acuity was worse than 0.7 or when the worker had a greater diference between the eyes (more than two […]

PURPOSE: To determine the socio-economic characteristics of the patients who were submitted to cataract surgery in a university hospital, to evaluate the accessibility to the tertiary health service and to determine the waiting time for cataract surgery. METHODS: A cross-sectional study of medical charts from 148 random patients who underwent cataract surgery during the first semester of 2007. RESULTS: The patients in this study had median of age of 70.5 years, and the major prevalence was of female (60.1%), caucasian […]

PURPOSE: The study objective is to determine the prevalence of amblyopia and amblyopiogenic factors in children from 3 to 6 years old at a health family program assisted community in Morro do Alemão-RJ. METHODS: A preschool children ocular evaluation cross sectional study will be submitted to an ophthalmic screening exam.The positive results were confirmed by oftalmologic examination under cicloplegia inside of the health centre. Were applied a semi-structure questionnaire to the health members of the health centre team and to […]

PURPOSE: Assess the clinical and topographical effects of corneal collagen crosslinking in patients with keratoconus on Brazilian population. METHODS: Thirty seven eyes of 37 patients (22 female and 15 male) with diagnosis of progressive keratoconus and corneal paquimetry higher than 395 micra, were treated with riboflavin and ultraviolet A radiation, over 30 minutes, to induce corneal collagen crosslinking. Keratometric values were compared as well as the best corrected visual acuity, before and after the procedure, with ranges of 40 and […]

PURPOSE: To identify aspects of the image test to arrive at the sure diagnosis of intumescent white cataract. METHODS: Two groups of eyes with white and nigra cataracts were studied using clinical and laboratorial criteria. RESULTS: The width of the lens > 5.36mm and its spherical aspect are the two data that provided us with a sure diagnosis of intumescent white cataract. CONCLUSION: The use of the image test provides data for the sure diagnosis of intumescent white cataract.

The authors relate an uncommon case of macular hole following electric burn. They describe an uncommon physiopathology, which is different from traumatic and idiopathic macular hole.

This bibliographic review work is pointed to the effects of altitude hypoxia on sight. It intends to contribute for the identification of signs and symptoms of hypoxia during high altitude exposition. The understanding of the terrestrial atmosphere and the laws of physics related to gas behavior under atmospheric pressure variation are very important for the correct diagnosis of the dysbarisms, hypoxia, decompression disease and others, by the aerospace health professionals. The atmospheric environment that pilots are exposed is able to […]
