title: Etiology and Clinical Features of Ocular Inflammatory Diseases in a Tertiary Referral Centre in Sydney, Australia.
abstract: OBJECTIVE
  To report the pattern of uveitis in patients attending a tertiary uveitis service in Sydney, Australia.
  
  
  METHODS
  The charts of patients seen between January 2009 and December 2015 were retrospectively reviewed. Data pertaining to patient demographics, eye examination on presentation, work-up and final diagnoses were collected.
  
  
  RESULTS
  The total number of patients with uveitis seen over this period was 1165. There were 650 males (56%) and 515 females (44%). There were 838 patients aged 17-60 years (72%) and 327 patients aged >60 years (28%). Uveitis was anterior in 735 patients (63%), posterior in 234 patients (20%), pan in 109 patients (9%), and intermediate in 87 patients (8%). The most common associations were HLA-B27+ve (264 patients; 22.8%), sarcoidosis (78 patients; 6.7%) and Fuchs (33 patients; 2.8%), while VZV (51 patients; 4.4%), HSV (49 patients; 4.2%), tuberculosis (49 patients; 4.2%) and toxoplasmosis (48 patients; 4.1%) were the most common infectious causes of uveitis. No identifiable association was found in 389 patients (33.4%). HLA-B27 was more common in the younger age group compared with the older age group (p<0.001, χ2-test), but there was no difference between the age groups for no identifiable cause (p value 0.24) and sarcoidosis (p value 0.08).
  
  
  CONCLUSIONS
  This retrospective case review reveals a broad spectrum of uveitis in a tertiary referral service in Sydney, Australia. It is comparable with other major studies around the world.
