title: Patterns of uveitis in patients admitted to a University Hospital in Riyadh, Saudi Arabia.
abstract: OBJECTIVE
  To analyze clinical patterns, causes, and systemic disease associations among patients with uveitis admitted to King Abdulaziz University Hospital.
  
  
  METHODS
  The authors retrospectively reviewed the medical records of 351 patients (600 eyes).
  
  
  RESULTS
  The study subjects consisted of 183 (52.1%) males and 168 (47.9%) females, with a mean age of 39.9 ± 14.2 years at presentation. The most common anatomic diagnosis was panuveitis (68.6%), followed by posterior uveitis (12.7%), anterior uveitis (12.7%), and intermediate uveitis (6.0%). The most common identifiable specific diagnoses were presumed tuberculous uveitis (PTU) (28.2%), Vogt-Koyanagi-Harada (VKH) disease (19.4%), Behçet disease (BD) (12.5%), and toxoplasmosis (8.2%). After a mean follow-up period of 29.5 ± 22.1 months, 63.5% of the eyes achieved visual acuity of 20/40 or better. Eyes from patients with PTU had the worst final visual outcome.
  
  
  CONCLUSIONS
  The most common anatomic diagnosis was panuveitis. PTU, VKH disease, BD, and toxoplasmosis were the most frequent specific diagnoses.
