[Morphologic aspects of therapy-resistant cytomegalovirus retinitis]

Intravenous ganciclovir treatment was performed in eight male AIDS patients with primary unilateral CMV-retinitis. Three patients developed slowly progressive CMV-retinitis in the fellow eye despite adequate dose of ganciclovir. These different CMV-manifestations are shown in a sequence of fundus pictures. Three types of CMV-lesions were observed in connection with this study. Untreated central lesions showed the aspect of crumbled cheese and ketchup. Untreated lesions in the peripherie were yellowish-white, granular, "dry" and showed in most cases no haemorrhages. Lesions appearing during treatment showed initially "dry" white opaque subretinal areas, turning later on to the typical aspect of untreated lesions. The progression could not be stopped by highdose ganciclovir i.v. and thus bilateral blindness resulted after 12 to 22 months. The level of CD4-lymphocytes in the blood was diminished in all patients, but much more in patients with progressive disease.
