title: Causes of visual loss associated with uveitis in a singapore tertiary eye center.
abstract: OBJECTIVE
  To identify the causes of visual loss associated with uveitis and its risk factors.
  
  
  METHODS
  Review of 359 patients attending a uveitis service.
  
  
  RESULTS
  Anterior uveitis (n = 229, 63.8%) was most common, followed by panuveitis (n = 55, 15.3%). There were 82 infective cases with 29.3% associated with tuberculosis. Visual loss occurred in 100 (27.9%) patients, of which 27 (7.5%) had severe visual loss. The main causes of visual loss were cataract (26%) and glaucoma (12%). Cystoid macular edema (14.8%) accounted for severe visual loss. Panuveitis was predictive for visual loss (p = 0.022, odds ratio (OR) 2.22) and severe visual loss (p = 0.01, OR 3.47). Posterior uveitis (p = 0.005, OR 5.01) and chronic uveitis (p = 0.008, OR 3.83) also showed higher risk for severe visual loss.
  
  
  CONCLUSIONS
  With panuveitis being the second most common presentation, early specialist referral is essential in preventing visual loss.
