NCT ID NCT03233646
First seen Feb 04, 2026 · Last updated Jun 23, 2026 · Updated 14 times
Summary
This study uses non-invasive eye scans (OCT and OCTA) to look for changes in the retina that might be linked to brain diseases like Alzheimer's, Parkinson's, and multiple sclerosis. Researchers aim to find early markers that could help diagnose or track these conditions. The study will include 2,000 adults with and without neurodegenerative diseases.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could lead to a simple, non-invasive eye test to help diagnose or monitor brain diseases like Alzheimer's and Parkinson's earlier.
What could go wrong
This is an observational study, not a treatment trial. It may not find reliable biomarkers, and results may not apply to all patients or stages of disease.
