A Novel Method for Transillumination

Abstract

Purpose: To introduce a cost-efficient device for transillumination in the management of uveal melanoma.

Methods: Todorich Illuminated Depressor is a ball-point depressor, designed to work with the 23-, 25- and 27-gauge Alcon Constellation endoillumination. It was invented to allow indentation and peripheral vitreous visualization for vitrectomy.

Results: Todorich depressor combined with endoillumination can also work as a device for transillumination for tumor localization. We started using this method of transillumination for the management of uveal melanomas since September 2020 and have successfully performed Ru-106 plaque brachytherapy for 10 cases of uveal melanoma. Three were large choroidal melanoma cases, and en bloc tumor resection by partial lamellar sclerouvectomy was successfully performed after precise localization of tumors using this method.

Conclusion: Alcon Constellation endoillumination capped with Todorich Illuminated Depressor is an affordable and viable alternative for transillumination of intraocular tumors.
