Purpose: To report the use of intravenous (IV) antiviral agents and intravitreal ganciclovir injections in three immunocompetent patients with severe acute retinal necrosis (ARN).
Method: Case series.
Results: Three immunocompetent patients, who had lost vision in the first eye due to ARN, received intensive treatment with IV foscarnet or acyclovir or ganciclovir and intravitreal ganciclovir injections for the treatment of severe ARN involving the fellow eye. The retinitis resolved and final visual acuity of the fellow eye improved to 20/20 in all three cases after a mean follow-up of 17 months.
Conclusions: Intensive treatment with a combination of two intravenous antiviral drugs and intravitreal ganciclovir injections was successful in the management of patients with acyclovir-resistant ARN and monocular status.
