title: Use of Aqueous Humor and Flow Cytometry in Ocular Sarcoidosis Diagnosis.
abstract: OBJECTIVE
  To report the use of flow cytometry on aqueous fluid to diagnose sarcoidosis in a patient with recurrent granulomatous anterior uveitis.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  Flow cytometry on aqueous fluid demonstrated a CD4/CD8 ratio >9.5, consistent with a diagnosis of sarcoidosis.
  
  
  CONCLUSIONS
  Flow cytometry on aqueous fluid may offer an additional pathway for diagnosing sarcoid anterior uveitis.
