Abstract
Purpose
To report a case of presumed bilateral acute retinal necrosis with delayed onset caused by herpes simplex virus type 2, medical treatment, and surgical approach.
Methods
Retrospective, interventional case described in a 51-year-old patient who complained of unilateral blurred vision with history of nonoperated retinal detachment in his fellow eye after posterior uveitis 11 years earlier.
Results
Ocular examination suggested diagnosis of acute retinal necrosis involving the posterior pole and sparing periphery. The causative agent was demonstrated using polymerase chain reaction analysis of the aqueous humor. Intensive medical treatment with intravenous acyclovir, intravitreous foscarnet, and corticosteroids was administered, slowing down but not stopping progression of the disease. Due to the monocular status of the patient and high probability of secondary retinal detachment, early vitrectomy was indicated.
Conclusions
Rapid and aggressive medical treatment is necessary in this condition. Bilateral involvement often occurs within weeks, but can also happen more rarely after several months or years, requiring long-term follow-up. Early surgical treatment is controversial but it is an option to be considered in certain cases.
