The ocular complications of acquired immune deficiency syndrome (AIDS) include: (1) a noninfectious microangiopathy, most often seen in the retina, consisting of cotton-wool spots with or without intraretinal hemorrhages and other microvascular abnormalities; (2) opportunistic ocular infections, primarily cytomegalovirus (CMV) retinitis; (3) conjunctival, eyelid, or orbital involvement by those neoplasms seen in patients with AIDS (i.e., Kaposi's sarcoma and lymphoma); and (4) neuro-ophthalmic lesions. In a series of 200 AIDS patients evaluated clinically, AIDS retinopathy was present in 66.5%. Sixty-four percent had cotton-wool spots, and 12% had intraretinal hemorrhages. Cytomegalovirus retinitis was diagnosed in 28% of AIDS patients. Neuro-ophthalmic lesions were found in 8% of all AIDS patients and were present in 33% of those patients with cryptococcal meningitis. Acquired immune deficiency syndrome retinopathy was present in 40% of 35 patients with the AIDS-related complex (ARC) and in 1.3% of 232 patients with asymptomatic human immunodeficiency virus (HIV) infection, evaluated photographically. These results suggest that the prevalence of AIDS retinopathy increases with increasing severity of HIV infection, and that CMV retinitis presents a significant vision-threatening problem in AIDS patients.

Human immunodeficiency virus (HIV) was recovered from multiple ocular tissues in three patients with acquired immune deficiency syndrome (AIDS). Consistently found in the retina, HIV was also detected in the conjunctiva, cornea, and iris. In two cases, HIV was detectable despite treatment with oral zidovudine. All three patients had bilateral cytomegalovirus (CMV) retinitis managed by intravitreal injection of ganciclovir. Culture of the retina for CMV was negative in all three cases. The finding of HIV in multiple ocular tissues is consistent with the neurotropic nature of the virus, and may explain some of the common ocular manifestations of AIDS such as AIDS retinopathy. Infection with HIV may predispose the retina to other opportunistic infections and may explain the high incidence of CMV retinitis in AIDS patients. This is the first report of HIV isolation from tissue within the eye.
