A retrospective study was made of 26 patients with AIDS who initially
presented with retinitis as the only clinical manifestation of cytomeg
alovirus infection (39 eyes), Sixty-five induction or re-induction the
rapeutic courses were administered with intravitreal ganciclovir. The
efficiency rate of therapy was 93.8%. Thirty-eight maintenance therape
utic courses (200 mu g/week) were evaluated. The non-compliance rate w
as 23%, Bilateral retinitis occurred in 44.4% of cases, The systemic a
dministration of therapy had to be substituted for the intravitreal ad
ministration in 32% of patients during the clinical course of their co
nditions, The mean survival rate was 9.5 months. Both retinal detachme
nt and vitreal hemorrhage, occurred in 5% of patients. When retinitis
is the first clinical manifestation of cytomegalovirus infection, ther
apy with intravitreal ganciclovir is efficacious to inactivate lesions
. Although bilateral retinitis and extraocular dissemination are commo
n, the mean survival rate is high.
