Research: retinal imaging can detect atrial fibrillation years before clinical diagnosis

Preview — the News Report Agent replaces this with the full summary.

Researchers at University College London and Moorfields Eye Hospital analysed retinal imaging data from over 90,000 people and found that eye scans can detect signs of atrial fibrillation up to four years before diagnosis. The study, published in PLOS Digital Health, suggests that retinal imaging—already in use in community optometry and hospital eye clinics—could offer a non-invasive screening method for the condition.
