Learn how your eyes can reveal health clues

Eye Opening: How Our Eyes Reveal Health Clues

Are your eyes the window to your soul? Perhaps. These two small organs can reveal much more about your overall health than you might expect.

Your eyes are rich with nerves, veins, and arteries, which can reflect the health of the rest of your body. That’s one of the reasons why getting your eyes examined regularly is so important: In addition to checking your vision, an eye exam can help identify potentially problematic changes to your overall health, like the conditions below:

Cataracts

Cloudy vision or glare may signal a cataract, a vision problem that’s common with age and can be corrected with surgery.

Diabetes

People with diabetes can develop microaneurysms and hemorrhages in the retina without vision changes in early diabetic retinopathy. Diabetic retinopathy is a condition that affects the eye’s blood vessels and is the most common cause of vision loss among people with diabetes.

High blood pressure

A simple eye exam can help diagnose high blood pressure or hypertension or help evaluate blood pressure control in people known to have high blood pressure. This condition can cause distinctive kinks and twists in the tiny blood vessels of the retina.

High cholesterol

A gray ring around your eye’s cornea (arcus senilis) or yellowish deposits of cholesterol in the eyelids (xanthelasma) may be a sign of high cholesterol, and that you’re at risk for cardiovascular disease. Cardiovascular disease can increase your odds of having a heart attack or stroke.

HIV and AIDS

The HIV virus can cause retinopathy similar to diabetic retinopathy. Eye infections in AIDS patients are often serious, and may lead to blindness. Eye doctors can sometimes detect these changes during eye exams. Early detection and treatment can help a patient maintain their vision.

Horner syndrome

Droopy eyelids, along with different-sized pupils, can be potential warning signs of a dangerous medical condition called Horner syndrome, which is linked to neck tumors and aneurysms and requires immediate medical attention.

Marfan syndrome

This genetic connective tissue disorder can be characterized by changes in the tissue that holds the lens of your eye in place. Marfan syndrome also typically causes extreme height, thinness, and long fingers, as well as an increased risk of aortic ruptures.

Myasthenia gravis

Droopy eyelids and double vision can be signs of myasthenia gravis, an autoimmune condition that also causes muscle weakness.

Skin cancer

If you develop a sore on or near your eyelid and have noticed that you’re losing eyelashes, you might have a type of eyelid carcinoma, or skin cancer. This type of skin cancer requires immediate medical attention: Some aggressive forms of eyelid cancer can lead to blindness or disfigurement if left untreated.

Thyroid disease

Eyes that protrude or bulge — a condition called exophthalmos — can be a common sign of Grave’s disease, also known as an overactive thyroid gland. This “bug-eyed” appearance can also cause red, inflamed eyes and vision changes, and is often accompanied by symptoms such as weight loss, rapid heartbeat, and anxiety or irritability.

Early Detection

Some of these changes to your eyes can be treated and possibly prevented if detected early. If you are experiencing any of these symptoms you should contact your doctor. Make an appointment at UPMC today.
