We report on a 29 year old severely compromised acquired immunodeficiency syndrome patient who developed retrobulbar optic neuritis 5 weeks after an episode of cutaneous herpes zoster infection.During the optic neuritis, varicella zoster virus could be demonstrated in the cerebrospinal fluid. The neuritis responded well to treatment with foscarnet,but three weeks into therapy varicella zoster retinitis developed.Additional treatment with intravenous acyclovir stopped progression of the retinitis and resulted in healing of the retinal lesions.This case suggests that retrobulbar optic neuritis can be regarded as a prodrome of imminent acute retinal necrosis.Early recognition and prompt therapy with combined antivirals may prevent the development of this devastating ocular complications of varicella zoster infection. |
