Ultrasound techniques in diagnosis of extrabulbar extension of uveal melanoma

Objective: To evaluate the utility of ultrasound examination in detection of extraocular extension of uveal melanoma.

Methods: A retrospective study of 170 enucleated eyes with ciliary body or/and choroidal melanoma and deep intrascleral tumor invasion with extrascleral extension.

Results: The extrascleral extension was detectable before enucleation in 31 eyes (18.24%), and tumor sizes varied from 1.5 to 15 mm. Ultrabiomicroscopy used for the anterior tumor assesment, shows the routes of extrascleral extension of uveal melanoma. uveal melanoma, extraocular extension, ultrasonography.
