[Ocular manifestations of Covid-19]

The most frequent ocular manifestation of the SARS-CoV-2 is a conjunctivitis. It is found in 1-3% of patients and has unusually a benign course. In those patients but also in patients without ocular involvement, the virus can be detected by PCR in conjunctival swabs or in the tears. Whereas the presence of the virus in the conjunctiva is proven, its transmission through the conjunctiva is still discussed. Despite the poor level of evidence, the use of protective eyewear is recommended. Ocular thromboembolic events have been described in Covid-19. They can be found in the context of the Covid-related coagulopathy. A multidisciplinary approach should be provided in these cases. In the ICU, severe ocular complications might be indirectly related to Covid-19 in ventilated patients.
