An eye scan may reveal signs of atrial fibrillation years before doctors detect the irregular heart rhythm, according to a study involving nearly 90,000 people.
Researchers from Moorfields Eye Hospital and University College London found that people with atrial fibrillation had changes in specific layers of the retina, the light-sensitive tissue at the back of the eye. Some of the same changes were also found in people who had not yet developed the condition but went on to develop it later.
