Extramacular disciform lesions simulating uveal tumors.
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.
