[Intravitreal ganciclovir in cytomegalovirus retinitis in AIDS].

A retrospective study was made of 26 patients with AIDS who initially presented with retinitis as the only clinical manifestation of cytomegalovirus infection (39 eyes). Sixty-five induction or re-induction therapeutic courses were administered with intravitreal ganciclovir. The efficiency rate of therapy was 93.8%. Thirty-eight maintenance therapeutic courses (200 micrograms/week) were evaluated. The non-compliance rate was 23%. Bilateral retinitis occurred in 44.4% of cases. The systemic administration of therapy had to be substituted for the intravitreal administration in 32% of patients during the clinical course of their conditions. The mean survival rate was 9.5 months. Both retinal detachment and vitreal hemorrhage occurred in 5% of patients. When retinitis is the first clinical manifestation of cytomegalovirus infection, therapy with intravitreal ganciclovir is efficacious to inactivate lesions. Although bilateral retinitis and extraocular dissemination are common, the mean survival rate is high.
