COVID-19 has become one of the most severe public health crises in recent years. Compared to other pathogenic coronaviruses, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is highly infectious. Due to the lack of specific and effective treatment or vaccines, disease prevention and early detection are essential for establishing guidelines to mitigate further spread. The potential role of the ocular system in COVID-19 is still not clear but it has gained increasing attention. Here, we reviewed both clinical and research evidence on the ocular manifestations associated with COVID-19, the presence of SARS-CoV-2 in ocular surface tissues and tears, and the potential role of the eye in contracting SARS-CoV-2.Keywords: COVID-19, SARS-CoV-2, eye, transmission, ACE2
