Abstract
The worldwide outbreak of the severe and acute respiratory coronavirus
disease (COVID-19) caused by the coronavirus strain SARS-CoV-2 is currently the focal
point of discussion due to the suffering this syndrome is causing to humanity. However,
the ophthalmological implications of this syndrome has not yet been well described. Both
eyes and tears as portals of entry and sources of contagion have been the subject of
debate by many authors. The purpose of this review is to summarize the evidence
currently available on COVID-19 and its ocular implications and manifestations, in both
animals and humans, with the aim to facilitate prevention and educate the
ophthalmological community on this subject. A review of the literature revealed that the
results of some studies suggest that ocular symptoms commonly appear in patients with
severe COVID-19 pneumonia and that it is possible to isolate the virus from the
conjunctival sac of these patients. Conjunctivitis is not a common manifestation of the
disease, but contact with infected eyes could be one route of transmission.
Consequently, ophthalmologists need to have correct prevention strategies in place. Some
guidelines regarding the prevention and management of ophthalmology clinics are
reviewed. However, well-designed trials should be conducted to rule out other ocular
manifestations that may result from COVID-19 infection and to understand the
transmission of the virus through the eyes.
