Central nervous system involvement after herpes zoster ophthalmicus

Abstract

Purpose: To report central nervous system involvement after varicella zoster virus infection. Methods: We evaluated the frequency and type of neurological complications in patients initially presenting with ophthalmic herpes zoster at an ophthalmological department in a Danish university hospital, over a 7-year period. Results: Of the 110 immunocompetent patients who presented with initial ophthalmic zoster, six (5.5%) suffered from neurological complications other than post-herpetic neuralgia. Four experienced isolated cranial motor nerve palsies, one patient had meningitis with a favourable outcome and one patient had severe encephalitis with a poor clinical outcome. Conclusions: Central nervous system involvement after varicella zoster virus infection is an uncommon, but potentially life-threatening, complication. Early recognition of neurological complications prompts acute, appropriate antiviral treatment. © 2008 The Authors Journal compilation © 2008 Acta Ophthalmol.
