There is more to Sars-CoV-2 than meets the eye
The Sars-CoV-2 coronavirus does not only cause infections of the respiratory tract. Other organ systems, such as the nervous system, can also be affected. In fact, Sars-CoV-2 mRNA has been detected in the brain in autopsies of patients who died from Covid-19. There is also growing evidence that coronaviruses can enter the retina of the eye, yet it is unclear which retinal structures are infected by Sars-CoV-2 and whether the retinal pathologies identified in Covid-19 patients are a direct or indirect result of retinal infection.
