AI Summary

A study by University College London and Moorfields researchers found that retinal imaging can reveal signs of atrial fibrillation up to four years before a clinical diagnosis. The researchers analyzed retinal scans from more than 90,000 individuals. They identified structural differences in the retinas of people who later developed atrial fibrillation compared with those who did not. The findings suggest that routine eye scans could serve as an early screening tool for the heart rhythm disorder.
