Because the epidemiology of AIDS is rapidly evolving, with HIV becoming more like a chronic disease, new information is needed on the incidence and course of ocular complications. We have little information about the effect of HAART therapy over time on changes in immune status and the risk of ocular complications of AIDS. More information is also needed to determine who is at risk for developing ocular complications of AIDS, and how treatment is affecting their visual function, quality of life, and survival.
