title: Choroidal hemangioma: Response to cryotherapy.
abstract: Choroidal hemangioma, a benign vascular tumor of the choroid, can frequently develop an effusive secondary retinal detachment. When such retinal detachment involves the macula, reduction in central vision occurs. Fluorescein angiography and radioactive prosphorus tests are helpful in accurately diagnosing choroidal hemangioma. Transscleral cryopexy, freeze-thaw-refreeze method, results in complete destruction and scarring of the choroidal hemangioma. Following treatment, subretinal fluid disappears, the macula becomes reattached, and central vision is restored.
