It then uses this data to analyse your risk of suffering a life-threatening cardiac event, such as a heart attack.
The device, powered by artificial intelligence, is far less invasive than a traditional diagnostic blood test but is just as accurate, according to Google. Google worked with California-based health-tech subsidiary Verily to create the AI algorithm, which tracked blood vessels at the back of the eye.
Previous research has shown that the shape and size of retinal vessels reflect a person's overall health, including their risk of heart disease and stroke.
Patients with a high blood pressure or who smoke are more likely to have weaker, thinner and damaged vessels than young and healthy individuals.
Using retinal images, Google says it was able to quantify this link and predict a patient's risk of a heart attack or other major cardiovascular event.
The algorithm was able to tell whether or not a patient would suffer a cardiovascular event in the next five years with a 70 per cent accuracy rate, Google said.
The results were similar to those achieved via testing methods that require blood be drawn to measure a patient’s cholesterol, which are typically 72 per cent accurate. <!-- Global site tag (gtag.js) - Google Analytics -->
