Researchers at the Centre for Eye Research Australia think that an eye exam can help to diagnose patients who have heart disease. Their work indicates that looking at the condition of the blood vessels of the retina at the back of the eye can give doctors an idea about the condition of blood vessels in the brain, heart, and kidneys.
The team is using computers to analyze thousands of images of eyes to determine whether this type of procedure can accurately indicate whether a person has heart disease. Finding people who are at high risk is important, since by the time the physical signs of heart disease are apparent, the individual has already sustained damage to their body.
If a non-invasive test like this one can help to diagnose heart disease earlier, then that is all the more reason to get eye exams regularly.
