Patients with an AIDS diagnosis according to 1993 CDC criteria, with or without ocular complications, are enrolled. Objectives are to: 1) monitor secular trends in the incidence of ocular complications of AIDS; 2) determine the effect of HAART-induced changes in immune status on the incidence and course of ocular complications of AIDS; 3) determine characteristics of patients that place them at high risk for ocular complications; and 4) evaluate effects of CMV retinitis treatments and other ocular complications on visual functions, quality of life and survival. Approximately 2,000 patients will be enrolled in this study. Enrollment of patients with CMV retinitis at baseline will be between 300 and 600 patients. All patients will be on a 3-month follow-up schedule. Patients with a major ocular complication will have clinic follow-up visits. Patients without a major ocular complication will alternate between telephone follow-up visits and clinic follow-up visits. Data will be collected from eye examinations, fundus photographs, visual function testing, medical history, quality of life assessments, laboratory studies and plasma and blood cells collection for banking. Banked specimens will be analyzed for HIV RNA levels and CMV DNA levels. Primary interest outcomes are incidence of CMV retinitis, other ocular complications and mortality. Other outcomes of interest include incidence of extra-ocular CMV disease and complications of therapies for ocular complications, sequelae of AIDS-related eye disease ( e.g., retinal detachment), visual function, and quality of life.
