Localized Retinal Nerve Fber Layer Defect in Patients with COVID-19

Abstract

Dear Editor, The novel coronavirus disease 2019 (COVID-19) is an extremely contagious disease that has been found to cause severe acute respiratory distress syndrome(1). Although ocular findings have mostly been limited to the anterior segment(2-4), studies have shown that viral ribonucleic acid can be detected in the retina of infected individuals(5). Accordingly, Marinho et al. had found lesions at the ganglion cell and inner plexiform layers of patients with COVID-19(6). Coronaviruses are capable of producing various ocular manifestations, ranging from conjunctivitis, and anterior uveitis to vision-threatening conditions, such as retinitis and optic neuritis(3).
