Data on the involvement of the ocular surface and its relationship with Coronavirus disease 2019 (COVID- 19) are still minimal and not univocal. The respiratory tract is the structure most affected by COVID-19, and the serious form of the disease is characterized by severe pneumonia, acute respiratory distress syndrome and hypercoagulation. However, accumulating evidence shows that other organs could be reached by the virus, thus causing further comorbidities. To date, the exact route/routes of transmission of COVID-19 are still unclear. The respiratory tract is probably not the only route of transmission for this viral infection and some authors have also speculated that COVID-19 droplets, or infected hands, could contaminate the conjunctiva, which could therefore represent the initial site of an infection spread. Theoretically, the role of the ocular surface, a biological site still relatively unexplored, appears scientifically relevant in understanding the Severe Acute Respiratory Syndrome - Coronavirus - 2 (SARS-CoV-2) infection. The purpose of this paper is to summarize the current literature in order to elucidate the potential role of tear and conjunctival sampling to detect SARS-CoV-2 for the diagnosis of COVID-19 and to monitor patients during follow-up.
