title: Predictors for tubercular uveitis: a comparison between biopsy-proven cases of tubercular and sarcoid uveitis.
abstract: OBJECTIVE
  To look for clinical parameters that will assist in making a diagnosis of tubercular or sarcoid uveitis in a South Indian patient population
  
  
  METHODS
  Retrospective, nonrandomized, comparative study of 51 patients with a diagnosis of biopsy-proven tuberculosis and sarcoidosis. These patients had a minimum of 1-year follow-up after initiating treatment for either disease. Multivariate logistic regression analysis was used to determine clinical predictors of tubercular uveitis.
  
  
  RESULTS
  The mean age group was 47.08 ± 11.19 years. There were 39 women and 12 men in the study. Multivariate logistic regression analysis shows likelihood of uveitis being tubercular in etiology using 3 variables: Schirmer test >10 mm, retinal vasculitis with areas of multiple, pigmented chorioretinal atrophy along blood vessels, and a positive Mantoux test 76.6%.
  
  
  CONCLUSIONS
  A combination of Schirmer test >10 mm, retinal vasculitis with areas of multiple, pigmented chorioretinal atrophy along blood vessels, and positive Mantoux test may be used clinically to differentiate tubercular from sarcoid uveitis in our patient population.
