title: Viral anterior uveitis.
abstract: OBJECTIVE
  With improvements in molecular diagnostics tests, viruses are increasingly being found to be associated with what was previously described as idiopathic anterior uveitis. This review presents the clinical features of viral anterior uveitis.
  
  
  RESULTS
  Herpes simplex virus/varicella zoster virus (HSV/VZV) are important causes of anterior uveitis, but other viruses including cytomegalovirus (CMV) and rubella are also found in a significant number of cases. The various viral anterior uveitides have similar features and should be suspected in eyes with diffuse, fine, stellate keratic precipitates, iris atrophy or ocular hypertension. Acyclovir remains the mainstay of therapy in HSV/VZV infections. CMV responds to ganciclovir, but the relapse rate is high and prolonged therapy may be required. Cataract and glaucoma are the main complications of viral anterior uveitis requiring appropriate management.
  
  
  CONCLUSIONS
  There is considerable overlap between clinical manifestations of the different viral anterior uveitides as well noninfectious hypertensive anterior uveitis syndromes. Hence, corticosteroids should be used with caution in these eyes if virus diagnostic tests are not available.
