Presumed Post-COVID Infection Retinitis – Clinical and Tomographic Features of Retinitis as a Post-COVID Syndrome

Abstract

ABSTRACT Purpose To study clinical and imaging features of presumed post-COVID infection retinitis. Method Retrospective case series of patients presenting with retinitis lesions with evidence of recent COVIDinfection. Retinal findings and optical coherence tomography (OCT) featureswere studied at baseline and follow-ups. Results Twenty-four eyes of 17 patients were included. Mean age was 36.57 ± 11.78 years. Baseline visualacuity (VA) was log MAR 0.97 ± 0.43. Fundus findings included retinitis patches(n = 24),hard exudates (n = 8), and superficial hemorrhages (n = 16). OCT featuresincluded neurosensory detachment (NSD, n = 20), hyperreflective inner layers (n= 24), acute macular neuroretinopathy (AMN, n = 8), hyperreflective foci (n =20). At final follow-up, VA was logMAR 0.43 ± 0.27. Retinitis patches persistedin four eyes, AMN in three eyes, and NSD in five eyes. Conclusion- Post- COVIDinfection retinitis adds to existing literature on post COVID syndromes.
