title: Clinical investigation of radiation retinopathy fundus and fluorescein angiographic features.
abstract: OBJECTIVE
  To investigate the fundus and fluorescein angiographic features in the patients with radiation retinopathy.
  
  
  METHODS
  Color fundus photography and/or fluorescein angiography from 13 patients with nasopharyngeal carcinomas received external beam radiation were retrospectively analyzed.
  
  
  RESULTS
  In this study, 26 damaged eyes of 13 patients developed some degree of radiation retinopathy. The earliest and most common finding was macular microvascular changes (microaneurysms and/or telangiectasia), which was observed in 100% (26/26) of the eyes. Intraretinal hemorrhages, macular capillary nonperfusion, and mascular edema were noted in 84%, 50%, and 42% of the eyes, respectively.
  
  
  CONCLUSIONS
  Radiation retinopathy is common after external beam radiation of nasopharyngeal carcinomas. The prominent changes include macular microvascular changes, intraretinal hemorrhages and macular capillary nonperfusion.
