Acute macular neuroretinopathy after Covid 19 in an eye with a congenital retinal macrovessel – a case report

Abstract

Purpose: To present a case of an acute macular neuroretinopathy (AMN) occurring after Covid 19 infection in an eye with a retinal macrovessel. Observations: We report a case of a 48-year-old woman who presented to our center with a 10-day scotoma in her right eye, in the context of a recently diagnosed Covid 19 infection. The funduscopy demonstrated a petaloid brown lesions temporal to the fovea in the right eye. A retinal macrovessel, passing adjacent to the lesions was also present. The left eye was normal. Multimodal imaging confirmed the diagnostic of AMN and optical coherence tomography angiography showed defects in the deep capillary plexus colocalizing with the lesions. Conclusions and importance: Ischemic events have been known to complicate macrovessel, and we reckon that the occurrence of AMN in this patient could have been the resultant of the conjunction of Covid 19 infection and abnormal retinal vasculature.
