Eye imaging and blood vessel changes in ultra-trail runners
Part of Eyes & vision clinical trials.
This study looks at how the back of the eye (retina and blood vessels) changes in people doing an ultra-trail race. It compares them to active people who are not doing the race, to see if intense running affects eye health.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older
- You are either registered for the UTMA 100 km solo ultra-trail race, or you are an active person who does about 4–6 hours of exercise weekly
- You are willing to have eye exams at the same times as the ultra-trail runners
- You do not have severe nearsightedness (more than -6 diopters) or diabetes
- You have no eye conditions like cataracts or macular degeneration that could affect imaging
- You agree to avoid smoking for 4 hours and caffeine for 1 hour before the study visits

This study uses an advanced eye scan (OCT-A) to look at tiny blood vessels in the back of the eye. It compares people with systemic blood vessel conditions (like high blood pressure or inflammatory disease) to healthy volunteers, to see if the eye scan can help predict or understand these diseases.
This study tests if a non-invasive eye scan (OCT-A) can detect changes in tiny blood vessels in the retina of people with chest pain caused by problems with the heart's small arteries (microvascular angina). If it works, it could be a simpler way to diagnose this condition.
This study uses detailed eye imaging to look for patterns that may go along with conditions like Alzheimer’s disease, memory problems, multiple sclerosis, or eye/vascular issues. It may help researchers better understand how eye findings relate to health and disease.
This study uses a special imaging test (OCT angiography) to look at blood flow around the optic nerve in people with advanced glaucoma. It aims to better understand how glaucoma affects eye circulation, which may help improve future care.
This study uses an eye scan called OCTA to look at blood vessels in the retina. It compares people with certain heart or blood vessel conditions (like high blood pressure or diabetes) to healthy volunteers to see if eye changes can help detect heart disease early.
This study uses a special, high-resolution camera to take detailed pictures of the back of the eye. It is testing the camera's ability to see changes in the retina for people who are healthy or have age-related macular degeneration, diabetic retinopathy, or other conditions that affect autofluorescence patterns.
