Radiation chorioretinopathy: unusual occurrence of intervortex venous anastomosis

BMJ Case Rep. 2023 May 26;16(5):e254471. doi: 10.1136/bcr-2022-254471.

Abstract

A woman in her 60s presented with vision blur in both eyes, a year post-radiotherapy for oral cancer. The best corrected visual acuity was 20/40 in both eyes. Posterior segment examination was remarkable for a unilateral intervortex venous anastomosis in choroid in her right eye, on the side of her face that had received radiation. Ultra-wide field indocyanine green angiography complimented the clinical findings. We discuss the ramifications of detection of this entity and suggest non-invasive methods of detection.
