    Snippet: Several studies have pointed to retinal involvement in COVID-19 disease, yet many questions remain regarding the ability of SARS-CoV-2 to infect and replicate in retinal cells and its effects on the retina. Here we have used human stem cell–derived retinal organoids to study retinal infection by the SARS-CoV-2 virus. Indeed, SARS-CoV-2 can infect and replicate in retinal organoids, as it is shown to infect different retinal lineages, such as retinal ganglion cells and photoreceptors. SARS-CoV-
    Document: Several studies have pointed to retinal involvement in COVID-19 disease, yet many questions remain regarding the ability of SARS-CoV-2 to infect and replicate in retinal cells and its effects on the retina. Here we have used human stem cell–derived retinal organoids to study retinal infection by the SARS-CoV-2 virus. Indeed, SARS-CoV-2 can infect and replicate in retinal organoids, as it is shown to infect different retinal lineages, such as retinal ganglion cells and photoreceptors. SARS-CoV-2 infection of retinal organoids also induces the expression of several inflammatory genes, such as interleukin 33, a gene associated with acute COVID-19 disease and retinal degeneration. Finally, we show that the use of antibodies to block the ACE2 receptor significantly reduces SARS-CoV-2 infection of retinal organoids, indicating that SARS-CoV-2 infects retinal cells in an ACE2-dependent manner. These results suggest a retinal involvement in COVID-19 and emphasize the need to monitor retinal pathologies as potential sequelae of “long COVID”.
