Eye and blood-vessel function study after COVID-19
Part of Infections, Lungs & breathing clinical trials.
This study measures how well the nerves in your retina and the tiny blood vessels in your eye “couple” (work together) after COVID-19. It may help researchers understand eye-related effects of COVID-19 and long COVID, and how these processes change over time.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 18 years or older and do not smoke
- Have a COVID-19 test history that matches one group: no infection, infection within 6 months, or long COVID
- Have a recent negative COVID-19 PCR test (not currently infected)
- Meet the eye requirements: your corrected vision must be at least 0.8 on the Snellen chart, and your eye measurement (ametro py) must be under 6 diopters
- Not be pregnant, planning pregnancy, or breastfeeding
Quick eligibility check

This study measures how blood flow in the eye changes in people with relapsing-remitting multiple sclerosis (RRMS) who previously had optic neuritis. The goal is to understand eye/brain blood-flow signals and how they may relate to MS.
This study compares eye blood-flow/brain-eye communication signals in people with glaucoma (or high eye pressure) versus people with normal eye tests. It may help researchers understand how glaucoma develops and progresses.
This study checks whether a specific eye-scanning technology gives consistent, repeatable results. It enrolls healthy adults to see if the test works reliably before being used more broadly.
This study looks at the tiny blood vessels in the eyes of people with Fabry disease using a special camera. It may help doctors understand how the disease affects the eyes over time.
This study measures blood flow and oxygen use in the retina (the light-sensing layer at the back of your eye) in adults with type 2 diabetes and in healthy adults. It may help researchers better understand how diabetes affects the eye.
This study measures blood flow in the eyes and how the retina (back of the eye) uses oxygen in people with diabetes who are starting a new type of diabetes medication. Researchers want to understand how these newer medications affect blood vessels in the eyes.
