“The ocular surface, coronaviruses and COVID-19,” an extensive literature review now published in Clinical and Experimental Optometry, considers a number of questions regarding SARS-CoV-2 transmission and the ocular surface. In a complex and fast-moving subject area, the paper provides a timely and useful overview of the current evidence base, along with its relevance for clinical practice.
The authors suggest it is possible coronaviruses may not bind to ocular surface cells and initiate infection. Additionally, hypotheses that the virus could travel from the nasopharynx or through the conjunctival capillaries to the ocular surface during infection are examined.
Published May 13, the paper is available at no charge to researchers, ECPs and other health care professionals via open access at https://onlinelibrary.wiley.com/doi/full/10.1111/cxo.13088.
