Your eyes are indeed the windows to your heart!
Researchers at Google have developed a new artificial intelligence system that can accurately predict the risk of heart attack, high BP or stroke by scanning images of people's retina, according to a new study published in the Nature Biomedical Engineering journal.
The algorithm, which has been created by Google AI and Verily Life Sciences, was fairly accurate at predicting the risk of a cardiovascular event.
The discovery may point to more ways to diagnose health issues from retinal images, researchers said.
The algorithm could distinguish the retinal images of a smoker from that of a non-smoker 71 per cent of the time.
Given the retinal image of one patient who later experienced a major cardiovascular event (such as a heart attack) and the image of another patient who did not, the algorithm could pick out the heart patient 70 per cent of the time.
This matches the accuracy levels of tests that require a blood draw to measure cholesterol.
However, with medical images, observing and quantifying associations can be difficult because of the wide variety of features, patterns, colours, values and shapes that are present in real images.
Retinal scanning can in future help scientists generate more targeted hypotheses and drive a wide range of research.
