Twenty years' delay of fellow eye involvement in herpes simplex virus type 2-associated bilateral acute retinal necrosis syndrome.

Abstract

To describe a case of acute retinal necrosis with concurrent encephalitis and determine the causative virus. The patient had a history of presumed acute retinal necrosis in the left eye at the age of 8 years and recurrent genital herpes. Diagnostic anterior chamber puncture of the eye and lumbar puncture for laboratory analysis. Polymerase chain reaction identified herpes simplex virus type 2 in the eye, and local antibody production to herpes simplex virus was demonstrated in the aqueous of this eye and in the cerebrospinal fluid. Herpes simplex virus type 2 may cause bilateral acute retinal necrosis with long delay of fellow eye involvement and concurrent encephalitis.
