Аннотация
Management of pediatric choroidal hemangioma complicated by large exudative retinal detachment can be challenging, with few options available. Limited data have been published on outcomes following proton radiotherapy (PRT) for management of these patients. In this retrospective case series, nine patients were treated with a low-dose PRT regimen of 20 Gy(relative biological effectiveness [RBE]) in 10 fractions, and two were treated with 15 Gy(RBE) in four fractions. Visual acuity improved in seven patients (64%) and remained stable in the remaining four (36%). In patients with imaging follow-up (10 patients), subretinal fluid resolved in nine patients (90%) and tumor thickness decreased or remained stable in 10 (100%). Complications were observed in eight of 11 patients (73%). One patient developed grade 2 cataract; otherwise, no grade ≥2 complications were observed.
