Eye damage in COVID-19. Part 1: Involvement of the eye in SARS-CoV-2 virus transmission and anterior segment complications

Abstract

In COVID-19, eye damage may develop at any stage of the disease. Viral ribonucleic acid has been found in ocular tissues, but the role of the eye as a route of infection is yet to be substantiated. Ophthalmic manifestations may be a typical feature of COVID-19 infection or they may develop several weeks after recovery. Ophthalmologists should be aware of possible relationships of an ophthalmic pathology with SARS-CoV-2 in order to obtain targeted case history, detect the specific signs, prescribe the necessary tests and thereby reduce the spread of the infection. These relationships are also important for early diagnosis and treatment of complications that threaten the patients’ life and vision. The first part of the review focuses on the possible involvement of the eye in SARS-CoV-2 infection and the spread of infection. Clinical manifestations of the anterior segment damage are considered.
