IDENTIFICATION OF ANTERIOR UVEAL TUMOR BORDER BY TRANSSCLERAL TRANSILLUMINATION AND AN OPHTHALMIC ENDOSCOPE

PURPOSE: To report a method for identifying the borders of anterior uv eal tumors in deeply pigmented eyes. METHOD: The borders of the anteri or uveal tumors were marked by transscleral transillumination with a f iberoptic light and observed from the vitreous cavity using an ophthal mic endoscope, RESULTS: The ophthalmic endoscope disclosed a bright or ange spot by transscleral transillumination of a normal uvea in deeply pigmented eyes. Two anterior uveal melanomas and one adenocarcinoma o f the nonpigmented ciliary epithelium did not transmit light through t he tumors, CONCLUSION: With an ophthalmic endoscope and transscleral t ransillumination, the borders of ciliary body tumors can be identified and clearly demarcated, even in deeply pigmented eyes.
