Summary

This pilot study looks at whether a simple, non-invasive eye scan (OCT-A) can detect early signs of memory decline in people with atrial fibrillation, a common heart rhythm disorder. Researchers will compare retinal blood vessel patterns in 40 patients with and without mild cognitive impairment. The goal is to see if the retina, often called a 'window to the brain,' could become a practical screening tool for cognitive decline in this high-risk group.

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 point toward a simple, non-invasive eye scan to help identify early memory problems in people with atrial fibrillation.
What could go wrong: This is a small, early pilot study with only 40 participants, so results may not apply to everyone. It is designed to test feasibility, not to prove a screening tool works yet.
