A 40-year-old male presented with reduced vision in the right eye for one week. He had a history of nasopharyngeal carcinoma for which 34-Gy radiation was administered. The best-corrected visual acuity (BCVA) was 20/40 in the right eye and 20/20 in the left eye. Anterior segment examination suggested a bilateral early posterior subcapsular cataract. Fundoscopy revealed bilateral localized telangiectasia and macular edema in the right eye. Diagnosis of bilateral extremely delayed onset radiation retinopathy with right eye macular edema was made. Three doses of intravitreal bevacizumab injection were administered in the right eye. The patient was lost to follow-up due to COVID-19 and presented with recurrence.
