On: Retina Blood Vessels Predict Common Fatal Diseases

If you want to look for arterial disease, then looking at arteries is a good idea. The ones in the retina are the easiest to see. All med students are trained in ophthalmoscopy, and will be able to detect retinal changes associated with long term diease. The studies use computers to scan digital photographs to actually measure arterial diameters and other predictive signs. The studies are based on these photographs. Using this quantitative approach is fairly new, and the long term study results are just coming in. It's not the same thing as your doctor detecting the obvious changes with an ophthalmoscope, chinese medicine or a palmistry-alike.
