Article:

Purpose: Infection by the SARS-CoV2 virus results in an immune dysregulated state which can predispose to reactivation of Herpes viruses. This report describes the development of Acute Retinal Necrosis (ARN) in two patients who had recovered from SARS-CoV2 infection.Methods: Observational report of two consecutive patients who presented with ARN after having recovered from SARS-CoV-2 infection.Results: Case 1 was a 5-year-old child with extensive peripheral necrotizing retinitis. Case 2 was a 61-year-old gentlemen with bilateral retinal detachment with sieve-like breaks and optic atrophy. Both patients had recovered from SARS- Cov-2 infection 1 month ago. PCR from vitreous sample of both patients was positive for Herpes simplex virus. Case 1 was treated with oral valacyclovir. Case 2 underwent surgery in both eyes for retinal detachmentConclusion: Immune dysregulation after COVID-19 infection can result in reactivation of herpesvirus and may lead to development of ARN.
