摘要
Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection could also cause ocular complications in 2%to 60%of infected patients.The need for an efficient COVID-19-related ocular finding detection and management pathway has sparked interest and activity in research looking for SARS-CoV-2 impact on all eye structures,especially the retina[1]that serves as an entrance gate,since retinal epithelium,arteries,and veins containing angiotensin-converting enzyme 2 represent a target for SARS-CoV-2 virus.The pathophysiological process is caused by a myriad of inflammatory reactions that damages retinal vessels through complex dysregulated functions of endothelium,platelet followed by hypercoagulability[2]manifesting as a central retinal artery(CRAO),central retinal vein occlusion(CRVO),and branch retinal vein occlusion in patients suffering from systemic polymorbidity or generally healthy without vascular risk factors,as well as young persons.It is still the case that the uncontrolled spread of COVID-19 leads to the evolution of new variants that continue to cause CRAO/CRVO[3,4]dominantly presented by cases of retinal vein occlusion[5].
