The eyes may offer a « window into the soul, » as poets say, but they also have a lot to say about your health.
Dry eyes can be a sign of rheumatoid arthritis. High levels of cholesterol can cause a white, gray or blue ring to form around the colored part of your eye, called the iris. A coppery gold ring circling the iris is a key sign of Wilson’s disease, a rare genetic disorder that causes copper to build up in the brain, liver and other organs, slowing poisoning the body.
And that’s not all: Damage to blood vessels in the back of your eye, called the retina, can be early signs of nerve damage due to diabetes, high blood pressure, coronary artery disease, even cancer, as well as glaucoma and age-related macular degeneration.
