COVID-19 is a newly defined disease, affecting the respiratory
system. It is caused by a novel coronavirus, called Severe Acute
Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The growing
importance of the outbreak led the World Health Organization
(WHO) to declare it a public health emergency of international
concern on 30 January 2020 and to later officially describe it as a
pandemic on 11 March 2020. Italy was the first European country
to be heavily impacted by COVID-19, with the number of cases
and deaths caused by the virus surging in the months of March and
April 2020. Ophthalmologists represent a high-risk category
for the spread of the infection, mainly because the examination demands
close contact with the patient, exposing the clinician to tear,
conjunctival secretions and to aerosol droplets
