The exposure to ultraviolet radiation is associated with the beginning of ocular pathologies like keratites, cataract, age-related macular degeneration and pterygium. This radiation is divided in 3 bands according to the wave length: Uv-A (320-400), Uv-B (290-320), Uv-C (100-290). The optic industry developed ultraviolet filters to intraocular lenses, contact lenses and spectacle lenses. PURPOSE: The issue of this work is to estimate the efficacy of ultraviolet contact lenses with high hydration. METHODS: Six types of high hydrated contact lenses from […]

PURPOSE: To estabilish the prevalence of the ametropias and eye diseases, in the year 2001, within a preschool and school population in Alto da Boa Vista favelas (slum), in the city of Rio de Janeiro, Brazil. METHODS: Transversal observational study during an ocular health campaign in public education schools. The children that have shown visual acuity fewer than 0.8 or abnormally were referred by trained volunteers to avaliation by ophthalmologists from the Benjamin Constant Institute. RESULTS: From the 1800 children […]

In order to assure corneal transparency after injury the effective removal of myofibroblasts is fundamental. The corneal myofibroblasts display platelet activator factor receptor on its surface. The platelet concentrate is one of the richest sources of essential growth factors, reducing bleeding, inflammation, scaring time, thus speeding up the closing of the ulcers. We report a case which provides evidence of clinical improvement with concentrate platelet eyedrops on a non responsive trophic corneal disease.
