What’s known
The coronavirus has been shown to cause serious eye diseases in animals
but ocular symptoms in humans are rare and mild. Recent studies have
defined endothelial damage as one of the most prominent causes of
systemic vascular thromboembolic and inflammatory manifestations
associated with Covid-19. Sars-CoV-2 may exhibit direct ocular diffusion
through two blood-retinal barriers (BRBs) or associated with thrombotic
sensitivity identified in Covid-19.
