Research progress on ocular diseases associated with SARS-CoV-2

Abstract

The corona virus disease 2019(COVID-19)in 2019 has shown a global pandemic status in a short time since its outbreak, and many variants of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)were highly infectious and pathogenic. SARS-CoV-2 may infect tissue cells through the mediation of angiotensin-converting enzyme-2(ACE2)and transmembrane serine protease 2(TMPRSS2), leading to different diseases. Clinically, respiratory, cardiovascular, and gastrointestinal systems diseases are relatively common; many patients also seek medical attention based on eye symptoms as their main complaint. Compared with severe systemic diseases, eye-related symptoms are easily overlooked. This article reviews the pathogenesis and cases of various eye diseases related to SARS-CoV-2, aiming to enhance clinicians' attention to SARS-CoV-2-related eye diseases, avoid delaying the disease and causing irreversible loss of vision, and provide new ideas for the prevention and treatment of eye diseases.
