Intranasal infection of mice with SARS-CoV-2 led to retinal inflammation and elevated viral titers in the lungs and brain
The prolonged presence of SARS-CoV-2 S protein in ocular tissues (thirty days after the intravitreal injection) resulted in microaneurysms, retinal atrophy, and retinal vein occlusion.

Individuals with long COVID syndrome have reduced corneal innervation and increased density of corneal dendritic cells more than 20 months after acute COVID-19
These results show a decrease in corneal nerve density and branch density, as well as an increase in dendritic cell density in patients with long COVID in comparison to the control group.
The mRNA COVID-19 vaccination increases the risk of retinal vascular occlusion
The overall risk of all forms of retinal vascular occlusion was 2.19 times higher in the vaccinated cohort than in the unvaccinated cohort within two years after COVID-19 vaccination.
