Acute retinal necrosis syndrome treated with vitrectomy and intravenous acyclovir.

Acute retinal necrosis syndrome in a healthy 32-year-old man was treated successfully with systemic acyclovir and corticosteroids in combination with vitrectomy, 360 degrees encircling band and transscleral cryocoagulation. Herpes simplex virus antibodies were detected in the vitrectomy aspirate supporting the current view that acute retinal necrosis is caused by viruses of the herpes group.
