title: Extramacular disciform lesions simulating uveal tumors.
abstract: OBJECTIVE
  The purpose of this study is to identify clinical, ultrasonographic, and fluorescein angiographic features of extramacular disciform lesions that allow differentiation from uveal tumors.
  
  
  METHODS
  This was a retrospective study of 19 patients referred to our ocular oncology unit with a possible malignancy who had a diagnosis of an extramacular disciform lesion made after complete evaluation.
  
  
  RESULTS
  The level of accuracy for each diagnostic technique alone was as follows: clinical (79%), ultrasonography (83%), and angiography (83%). Fluorescein angiography had limited utility because of severe media opacities in seven cases. No tumor developed an intraocular malignancy during the follow-up period.
  
  
  CONCLUSIONS
  A combination of the above, noninvasive techniques can be used to correctly diagnose extramacular disciform lesions.
