Mild type acute retinal necrosis syndrome involving both eyes at three-year interval.

A 44-year-old man was seen as having acute retinal necrosis syndrome involving both eyes at an interval of 3 years. The cement-like exudates typical to this disease were observed in the fundus of both eyes; they were self-limiting, finally resulting in retinochoroidal degeneration without retinal detachment before becoming confluent. The patient showed an elevation of the convalescent antibody titer to varicella-zoster virus in the aqueous humor during the second eye involvement. We suggest that there exists a self-limiting mild type of acute retinal necrosis syndrome of which the present case is an example.
