RESUMO
Fourteen families with genetically determined posterior retinal dystrophies were studied by fluorescein angiography. With one exception, the families could be segregated into two clearly defined categories, one in which every member had a dark choroid, and one where each had a light choroid. This implies that the fluorescein angiography provides a means of subdividing certain of these disorders into more specific disease groups.

Four patients with retinitis pigmentosa and either disc or peripheral retinal neovascularization with recurrent vitreous hemorrhage are described. One patient with peripheral retinal neovascularization also had rubeosis and neovascular glaucoma. The effects of relative hyperoxia on the retinal microcirculation in retinitis pigmentosa as well as intraocular inflammation may account for such changes. Laser photocoagulation appears effective in preventing vitreous hemorrhage in these patients, but systemic administration of corticosteroids did not cause the new vessels to regress.

Twenty-five ambulatory patients with acquired immunodeficiency syndrome (AIDS) were studied over a 6-month period. Fourteen (56%) of the patients were heterosexuals with a history of intravenous drug abuse. Ocular involvement was seen in 40% of patients, cotton-wool spots being the major manifestation. Findings consistent with cytomegalovirus retinitis were seen in only one patient. Ophthalmologists should be aware of the ocular findings and epidemiology of AIDS.
