A blood glucose test is the gold standard for spotting diabetes, but researchers in Michigan may have found another way. They're using a non-invasive device that takes specialized images of the eye.
The images are used to detect metabolic stress and tissue damage, which occur even before symptoms of the disease show up in the blood. It just takes about five minutes to test both eyes. The device specifically measures levels of Flavo-protein auto-fluorescence, which are significantly higher in people with diabetes.
Researchers have already filed for a patent and hope to get this on the market as soon as possible.
