Eye blood vessel signs of nerve damage in multiple sclerosis

Retinal microvasculature as a predictor of neurodegeneration in multiple sclerosis

NIH-funded research Portland VA Medical Center · NIH-11329775

This project uses a quick, noninvasive eye scan to look for tiny blood vessel changes that may show nerve damage in people with multiple sclerosis.

What this research studies

You will be invited to a clinic visit where providers will do neurologic and vision exams and ask about your walking, symptoms, and quality of life. A painless optical coherence tomography angiography (OCTA) scan will image the tiny blood vessels in your retina as a window into brain blood vessel health. The study will compare these eye blood vessel measures with patient-reported symptoms and objective tests of nerve and walking function. This observational work aims to see if the eye scan can serve as a useful marker of neurodegeneration in MS.

Who could benefit from this research

Good fit: People living with multiple sclerosis who can travel to clinic visits and complete vision and neurologic testing and questionnaires are ideal candidates.

Not a fit: People without MS or those with eye conditions that prevent clear OCTA imaging are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this could help doctors detect early nerve damage in MS using a painless eye scan and guide treatments to protect walking and quality of life.

How similar studies have performed: Previous eye imaging studies in MS have found retinal thinning and vascular changes, but using OCTA as a practical surrogate for CNS neurodegeneration is relatively new and still being tested.
