3D WrapTM Ultra-Widefield Reconstruction in Stereotactic Radiosurgery for Choroidal Melanoma

Abstract

Choroidal melanoma (CM) is the most commonly diagnosed primary intraocular malignancy in adults. Gamma knife radiosurgery (GKR) has demonstrated reliable results in the treatment of CM, but it is limited by the risk of radiation-induced ocular complications. To optimize the dose of radiation focused on the tumor, and limit side effects, the eye should be properly immobilized before treatment. A recently released ultra-widefield imaging instrument (Optomap California; Optos, Dunfermline, Scotland, UK) allows for an interactive three-dimensional (3D) virtual reconstruction of the globe, called 3D WrapTM. The authors share their experience with this rapid, reliable, and relatively easy support in planning globe positioning before GKR treatment.
