title: Anterior uveitis investigation by Canadian ophthalmologists: insights from the Canadian National Uveitis Survey.
abstract: BACKGROUND
  Anterior uveitis can be the result of a number of underlying etiologies and is commonly seen in ophthalmology practice. The clinician must choose from a battery of potential investigations. A nonselective approach to testing is costly and inefficient and can lead to misinterpretation of false positive results. The purpose of this study was to identify investigation patterns of ophthalmologists in Canada for anterior uveitis and to make evidence-based recommendations for appropriate tests that could lead to improved patient care and more cost-effective use of health care resources.
  
  
  METHODS
  A cross-sectional survey of practicing ophthalmologists, fellows, and residents in Canada was conducted in September 2004. The survey instrument was an 11-item questionnaire mailed to 1196 physicians in Canada.
  
  
  RESULTS
  A total of 498 (42%) physicians responded to the survey. A wide range of tests were chosen when respondents were presented with 5 scenarios for anterior uveitis and asked what investigations they would order. Many of these tests have low diagnostic yields because they lack the sensitivity and specificity to be used as routine investigations in the setting of anterior uveitis.
  
  
  CONCLUSIONS
  Increased education and awareness could lead to more cost-effective and efficient investigations in the setting of anterior uveitis. On the basis of evidence from a review of the literature, we make recommendations for investigations that should be considered in patients with anterior uveitis.
