Summary: Researchers discovered that SARS-CoV-2 can penetrate the blood-retinal barrier, potentially causing long-term eye damage. The study found that the virus induces a hyperinflammatory response and cell death in the retina.

This breakthrough emphasizes the importance of monitoring eye health in COVID-19 patients. The findings could lead to new therapies for preventing and treating COVID-19-related eye complications.

The blood-retinal barrier is designed to protect our vision from infections by preventing microbial pathogens from reaching the retina where they could trigger an inflammatory response with potential vision loss.

But researchers at the University of Missouri School of Medicine have discovered the virus that causes COVID-19 can breach this protective retinal barrier with potential long-term consequences in the eye. 

Pawan Kumar Singh, PhD, an assistant professor of ophthalmology, leads a team researching new ways to prevent and treat ocular infectious diseases.
