title: West Nile virus-associated optic neuritis and chorioretinitis.
abstract: OBJECTIVE
  To report the new ocular and neurologic features of West Nile virus (WNV) meningoencephalitis.
  
  
  METHODS
  Observational case report.
  
  
  METHODS
  A 55-year-old woman presented with headache, stiff neck, visual loss, and fever 10 days after a weekend camping trip. Examination revealed vitritis, creamy yellow circular chorioretinal lesions, and peripheral visual field loss.
  
  
  RESULTS
  Laboratory investigation indicated the patient was suffering from WNV meningoencephalitis with neuro-ocular involvement.
  
  
  CONCLUSIONS
  Ophthalmologists and infectious disease specialists should recognize that the WNV infection spectrum may include ophthalmic findings, specifically optic neuritis and multifocal chorioretinitis.
