简介
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has spread rapidly across the globe to cause a pandemic. Although it is known to be transmitted via droplets, alternative modes of transmission remain unknown. Transmission through infected ocular tissue or fluid has been a controversy. 1, 2 It is hypothesized that the nasolacrimal system can act as a conduit for viruses to travel from the upper respiratory tract to the eye. Hence, ocular tissue and fluid may represent a potential source of SARS-CoV-2. In this study, we attempted to determine the possibility of transmission through tears by assessing for the presence of SARS-CoV-2 with viral isolation and quantitative reverse-transcription polymerase chain reaction (RT-PCR) analysis. As patients were being monitored clinically via routine nasopharyngeal swabs, these results were compared with those of tears to understand further patterns of viral …
