Identification of anterior uveal tumor border by transscleral transillumination and an ophthalmic endoscope.
OBJECTIVE
To report a method for identifying the borders of anterior uveal tumors in deeply pigmented eyes.


METHODS
The borders of the anterior uveal tumors were marked by transscleral transillumination with a fiberoptic light and observed from the vitreous cavity using an ophthalmic endoscope.


RESULTS
The ophthalmic endoscope disclosed a bright orange spot by transscleral transillumination of a normal uvea in deeply pigmented eyes. Two anterior uveal melanomas and one adenocarcinoma of the nonpigmented ciliary epithelium did not transmit light through the tumors.


CONCLUSIONS
With an ophthalmic endoscope and transscleral transillumination, the borders of ciliary body tumors can be identified and clearly demarcated, even in deeply pigmented eyes.
