Ocular Symptoms in Patients with Confirmed Covid-19 Infection: A Survey Study

Reports have shown that Covid-19 infection can be associated with eye symptoms. Through an online survey, researchers at the National Eye Institute want to learn more about eye symptoms associated with Covid-19 infection. With this survey, investigators hope to discover how common eye symptoms are in Covid-19 infection and how they relate to other Covid-19 associated symptoms. The survey is expected to take 10 to 20 minutes. You do not need to have had any eye symptoms in order to participate. You may participate if you are at least 18 years of age with a history of a confirmed positive Covid-19 test. Join by visiting or email
