Ocular complications of the acquired immunodeficiency syndrome

Abstract

The acquired immunodeficiency syndrome (AIDS) affects the ocular structures in several ways. Kaposi's sarcoma has been observed on the bulbar conjunctiva of the globe. Retinal complications, however, are of major concern. Cotton-wool spots are commonly seen in AIDS patients and are usually of no consequence, except that they must be distinguished from the early stages of cytomegalovirus (CMV) retinitis, seen in 20-40% of these patients. CMV causes a necrotic-type retinitis potentially leading to blindness. 9-[2-Hydroxy-1-(hydroxymethyl)ethoxymethyl]guanine (DHPG) has been found effective in the short-term treatment of this disorder. It is planned to use AS101 in the regimen to see if a long-term cure from this disease can be affected. Care must be taken in handling ocular tissue of AIDS patients or the re-use of ophthalmic instruments touching the eye of AIDS patients since the human immunodeficiency virus has been found in these structures.
