New study finds SARS-CoV-2 causes retinal infection

Can coronavirus disease 2019 (COVID-19) affect the eye? New research suggests the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can enter the eye and infect photoreceptor and retinal ganglion cells. In addition, SARS-CoV-2 infection increases the expression of several inflammatory genes, including the cytokine interleukin 33 (IL33), which is linked to COVID-19 disease and retinal degeneration.
