Chorioretinal anastomosis as a rare complication of radiation retinopathy

摘要

Editor,Posterior segment complications following cephalic radiotherapy are mainly the result of retinal vascular changes, including endothelial cell loss, retinal capillary occlusion, micro-aneurysm formation and occlusive retinal endarteritis. Principal clinical features of radiation retinopathy are microaneurysms, macular oedema, hard and soft exudates, telangiectasias and retinal haemorrhages (Amoaku & Archer 1990). We describe a case of central macular chorioretinal anastomosis, an unusual late manifestation of radiation retinopathy complicating cephalic radiotherapy.
