Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also known as COVID-19, is much more difficult to transmit through the ocular surface than that through the mouth and nose. However, the available evidence has suggested the possibility of ocular surface transmission, especially in medical staff. In this paper, we describe the existing SARS-CoV-2 ocular surface symptoms, the possible mechanism of SARS-COV-2 entering ocular surface cells and SARS-COV-2 transmission through ocular surface. In addition, the existing and future possible research directions of SARS-CoV-2 transmission through ocular surface were analyzed, so as to provide new ideas and methods for clinical treatment of SARS-CoV-2 from the perspective of ocular surface. © 2021, Xinxiang Medical University.
