title: Varicella Zoster-related Occlusive Retinal Vasculopathy--A Rare Presentation.
abstract: OBJECTIVE
  To report a case of occlusive retinal vasculopathy following varicella zoster infection in an immunocompetent adult.
  
  
  METHODS
  Observational case report.
  
  
  METHODS
  A patient with defective vision following chickenpox was evaluated with fluorescein angiography, spectral domain optical coherence tomography and fundus auto fluorescence.
  
  
  RESULTS
  Fundus showed multiple cotton wool spots and a well-demarcated zone of retinal ischemia in the posterior pole with normal optic disc without any evidence of anterior or posterior uveitis. Fluorescein angiography, spectral domain optical coherence tomography and fundus auto fluorescence findings revealed occlusive vasculopathy as the cause of defective vision.
  
  
  CONCLUSIONS
  We report a hitherto undescribed case of purely occlusive vasculopathy following varicella zoster infection without features of vasculitis or anterior and posterior uveitis in an immunocompetent individual.
