title: Central nervous system involvement after herpes zoster ophthalmicus.
abstract: OBJECTIVE
  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.
