Role of Eyes and Eyes Protection Amidst SARS-CoV-2 Infection
Severe Acute Respiratory Syndrome Coronavirus 2 pandemic has infected millions of people. Theconjunctival epithelium is easily exposed to infectious droplets and body fluids making eyes apotential route and reservoir of the infection. The CD147 and ACE2 receptor has been demonstratedin ocular surface cells, which implies that these cells may facilitate as a portal of entry for transmissionof Severe Acute Respiratory Syndrome Coronavirus 2. Despite low viral load in tears and conjunctivalswab, the negative RT-PCR results cannot exclude the possibility of the presence of Severe AcuteRespiratory Syndrome Coronavirus 2 in ocular secretions. Pathogens might be transported byconstant tear flow through the lacrimal duct system to the respiratory tract causing infection. Eyesare unlikely to be the main transmission route, however, their role in the transmission of SevereAcute Respiratory Syndrome Coronavirus 2 cannot be overlooked. Therefore, proper eye protectionshould be instituted while attending Severe Acute Respiratory Syndrome Coronavirus 2 positiveindividuals, especially by health professionals.
