Efficacy of proton therapy in circumscribed choroidal hemangiomas associated with serous retinal detachment

Objective: The purpose of the study is to evaluate the efficacy and safety of proton therapy in complicated circumscribed choroidal hemangiomas. Design: The study design was a retrospective review, Participants: Studied were 13 patients (13 eyes) who had circumscribed choroidal hemangioma associated with serous retina[ detachment. Of these, four eyes previously underwent laser unsuccessfully. Intervention: Proton therapy including a total dose of 30 Cobalt-Gray-Equivalent was administered to Each eye. Main Outcome Nleasures, Patients were controlled for initial and final best-corrected visual acuity, slit-lamp examination, intraocular pressure, fundus examination, fluorescein angiography, and tumor thickness on B-scan ultrasonography. Results: The mean follow-up period was 26 months (range, 9-48 months), Retinal reattachment was obtained in all cases after a mean period of 52 days, The tumor height decreased in all cases, Visual acuity improved to two lines or more in eight eyes (62%) and reached 20/200 or more in nine eyes (69%), No radiation complication was detected during follow-up. Conclusions: Proton radiation seems to be effective and safe in the management of choroidal hemangioma associated with serous retinal detachment, It may be useful when photocoagulation can not be performed.
