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.

The authors describe four rare cases of polychromatic posterior corneal dystrophy, not describe in national literature. The opacities are deep in the stroma, dotlike, polychromatic, uniform in size, distributed from limbus to limbus, leading no reduction in visual acuity. It is also presented a bibliographic review of pre-Descemet’s dystrophy.

To describe the diagnosis and management of a optic disc haemorrhage probably caused by an acute and spontaneous posterior vitreous detachment. A single case-report of an optic disc haemorrhage probably caused by an spontaneous posterior vitreous detachment, in order to discuss the diagnosis, management and prognosis. Optic disc haemorrhage regression was observed after 6 hours of evolution without relapsing signals during the subsequent registers. The Scanning Laser Ophthalmoscopy revealed as an advanced alternative and efficient method in the vitreous detachment […]

Report of a case of posterior persistent hyperplastic primary vitreous (PHPV) case on a nine years old patient with low visual acuity on the left eye, referred by the school for ophthalmic evaluation. The PHPV can embrace a wide spectrum of ocular alterations involving retina, vitreous, optic nerve, macula, crystalline, iris and ciliary body besides anomalies like mycroftalmia and microcornea.

INTRODUÇÃO Amodernização das técnicas de cirurgias de catarata está hoje em avanço contínuo. A facoemulsificação é uma conquista importante. Com ela obtém-se uma rápida recuperação da visão com o mínimo de reação inflamatória, otimizando a cura, diminuindo o tempo de convalescência e improdutividade do paciente e de seus acompanhantes durante o período pós-operatório. O custo gerado por um procedimento como a facoemulsificação deve ser analisado em busca de meios de torná-lo o menor possível. Uma definição importante a se fazer […]

In the health decision chain, the physician has been progressively losing influence in favor of executives, managers, politicians, and more recently investors.
