Cytomegalovirus retinitis after immune reconstitution.

Cytomegalovirus (CMV) infection is the most common opportunistic infection that affects the retina in HIV-positive patients; it typically occurs in the setting of severe immune suppression (CD4 count less than 50 cell/microL). We present a case report of an HIV-infected patient in whom recurrent CMV retinitis developed after HAART and apparent immune reconstitution (CD4 count of greater than 500 cells/microL). This case report underscores that CMV infection may occur despite high CD4 counts among patients who experience only partial immune reconstitution.
