title: Frosted branch angiitis caused by Varicella Zoster virus in an immunocompetent patient.
abstract: BACKGROUND
  Frosted branch angiitis(FBA) is a panuveitis with sheating of all retinal vesssels.
  
  
  METHODS
  Herein we report an immunocompetent person who presented with fever, headache, atypical rash, and hazy vision. Ophthalmoscopy of both eyes revealed perivascular sheathing with frosted branch angiitis pattern in veins, patchy retinal hemorrhages. Aqueous PCR analysis turned positive for VZV.
  
  
  CONCLUSIONS
  This case illustrates that VZV should be considered in the differential diagnosis of retinal perivasculitis. Since a rapid and accurate diagnosis is crucial for prompt administration of antiviral therapy, PCR-based analysis of aqueous humor is a valuable tool for detecting viruses.
