title: Clinical Patterns and Causes of Uveitis in a Referral Eye Clinic in Qatar.
abstract: OBJECTIVE
  To determine the patterns and causes of uveitis in a referral eye clinic in Qatar.
  
  
  METHODS
  A retrospective study was conducted on all cases of uveitis that presented to the Uveitis Clinic at Hamad Medical Corporation from March 2007 to February 2011. All patients had detailed ocular, medical examination, and uveitis work up.
  
  
  RESULTS
  The study included 310 patients. Anterior uveitis was noted in 53.2% of cases (165/310), followed by panuveitis 16.8% (52/310), intermediate uveitis 16.5% (51/310), and posterior uveitis 13.6% (42/310). Causes of uveitis were determined in 69.7% (216/310) of cases. The most commonly identified causes of uveitis in our study were presumed ocular tuberculosis (14.5%), Fuchs uveitis (11.0%), Behçet disease (7.4%), and VKH disease (6.8%).
  
  
  CONCLUSIONS
  Anterior uveitis is the most common anatomic/clinical form of uveitis in Qatar and the etiologic diagnosis of uveitis should focus in particular on presumed ocular tuberculosis, Fuchs uveitis, Behçet disease, and VKH disease.
