Abstract
- We report the observation of a 31-year-old patient followed for a nasopharyngeal carcinoma since 2009, treated by locoregional radiotherapy, with a cumulative dose of 70 Gray. This case presented all ocular complications of radiotherapy; radiation retinopathy (RR), which is the most severe complication, could be diagnosed earlier and have a better prognosis if optic coherence tomography angiography (OCTA) was performed. She presented with a progressive decline in bilateral visual acuity. Ophthalmologic examination revealed bilateral posterior subcapsular cataract, radiation retinopathy, and optic neuropathy. The OCT B-scan showed more pronounced macular edema in the right eye. The OCTA revealed enlargement of the central avascular zone and loss of the deep and superficial retinal vascular network. The patient received three consecutive monthly intravitreal injections of anti-vascular endothelial growth factor (VEGF), without improvement in visual acuity. The aim of this case report is to present the contribution of OCT-A in the diagnosis of radiation maculopathy, and attribute these changes to ischemia at the level of the retinal vascular network.
