Role of Radiation Therapy for Choroidal Hemangioma: A Brief Review

Choroidal hemangioma is an uncommon benign vascular hamartoma. Depending on the extent of the involved choroid, it can be subtyped into circumscribed form that occurs sporadically as an isolated tumor or a diffuse form that occurs in association with Sturge-Weber syndrome. It appears as an orange-red mass, located commonly posterior to the equator and is mostly asymptomatic. Poor vision is attributed to exudative retinal detachment, cystoid macular edema, foveal distortion and refractive errors. Diagnosis is crucial and is aided by ancillary tests such as ophthalmic ultrasonography, fundus fluorescein angiogram and Indocyanine green angiogram.
