title: The risk of complications of uveitis in a district hospital cohort.
abstract: OBJECTIVE
  To establish the frequency and risk factors for visual loss in a primary referral cohort of hospital patients with uveitis.
  
  
  METHODS
  561 consecutive uveitis patients attending three district hospitals were recruited and the acuity at the end of the study period recorded. A retrospective case-control study of risk factors for visual loss (permanent loss of acuity <6/9) was performed. Risk factors examined included type of uveitis, age at onset of uveitis, race, type of systemic inflammatory disease, length of follow up, and treatment variables.
  
  
  RESULTS
  Visual loss of at least 6/12 in one eye was found in 111 patients (19.9%). Only four patients (0.7%) suffered severe bilateral visual loss (6/36 or less). Visual loss was associated with age at onset >60 years (odds ratio 3.9, 95% confidence interval (CI) 2.2 to 7.0, long follow up 2.0 (1.2 to 3.3) and a history of cataract surgery 3.9 (2.1 to 7.2). It was less likely in patients with acute anterior uveitis 0.2 (0.1 to 0.3).
  
  
  CONCLUSIONS
  The frequency of visual loss associated with uveitis in a district hospital cohort is less than that found in referral centres and levels of legal blindness are low. Although acute anterior uveitis has a low frequency of visual loss it contributes significantly to the total burden. The ocular co-morbidity of the elderly may contribute to the increased visual loss of late onset uveitis.
