Long COVID describes a range of ongoing health problems weeks or even months after recovering from COVID-19. Researchers have identified a link between changes to a person’s eyes—specifically the cornea—and the likelihood of having long COVID.
Nerve damage and an increased immune cell count in a person’s cornea are both tied to long COVID. These changes in the eye may be a way of identifying the impact of the virus and are most evident in those experiencing loss of taste and smell, headaches, dizziness and numbness. A simple eye test could soon identify long COVID and help start a person’s path to recovery with the appropriate rehabilitative care.
