We examined retinal tissue from eight human immunodeficiency virus type 1 (HIV-1) seropositive patients with acquired immunodeficiency syndrome (AIDS) or AIDS-related complex for evidence of dual infection with HIV-1 and cytomegalovirus. Culture demonstrated simultaneous infection with HIV-1 and cytomegalovirus in two of 13 retinal specimens. This was confirmed by both immunofluorescence and immunohistochemical staining. Moreover, coinfection of individual cells with cytomegalovirus and HIV-1 was observed by immunohistochemical staining. Infection of retina with cytomegalovirus or HIV-1 alone occurred in one and six of the 13 retinal specimens, respectively. HIV-1 antigens were present on scattered cells in all layers of the retina and on retinal vascular endothelium. HIV-1 was isolated from retinal tissue derived from eyes both with and without gross ocular lesions. Cytomegalovirus antigens were found in all layers of the retina, but not on vascular endothelial cells. The atypically rapid clinical progression of retinitis in one of the patients with dual HIV-1 and cytomegalovirus infection suggests the possibility that interactions between these two viruses may influence retinal disease in patients with AIDS.
