title: Clinical Patterns of Uveitis in an Iranian Tertiary Eye-care Center.
abstract: OBJECTIVE
  This study aimed to analyze the clinical patterns and etiology of uveitis in Isfahan, Iran.
  
  
  METHODS
  In this descriptive research, the records of 2016 patients with uveitis referred to a tertiary eye care centers were examined. Age, sex, clinical and anatomical features, and etiology of disease were recorded and analyzed.
  
  
  RESULTS
  The mean age of onset of uveitis was 33.76 years and the women/men ratio was 1.2/1.0. Anterior uveitis was the most common (42.9%) type followed by posterior (21.4%), intermediate (19.3%), and pan uveitis (16.31%). Noninfectious causes had more roles (76.5%) in the etiology of uveitis. A total of 43.9% of the patients had unknown etiology (idiopathic). The most common known etiologies were toxoplasmosis, Behçet disease and Fuchs heterochromic iridiocyclitis (FHI), respectively. In 15.6%, there was an underlying systemic disease.
  
  
  CONCLUSIONS
  There were some differences in the clinical and etiologic pattern of uveitis in Isfahan. Environmental, genetic, and geographical factors may contribute to this difference.
