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.\nYour eyes are rich with nerves, veins, and arteries, which can reflect the health of the rest of your body. That\u2019s 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:\nCataracts\nCloudy vision or glare may signal a cataract, a vision problem that\u2019s common with age and can be corrected with surgery.\nDiabetes\nPeople 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\u2019s blood vessels and is the most common cause of vision loss among people with diabetes.\nHigh blood pressure\nA 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.\nHigh cholesterol\nA gray ring around your eye\u2019s cornea (arcus senilis) or yellowish deposits\u00a0of cholesterol in the eyelids (xanthelasma) may be a sign of high cholesterol, and that you\u2019re at risk for cardiovascular disease. Cardiovascular disease can increase your odds of having a heart attack or stroke.\nHIV and AIDS\nThe 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.\nHorner syndrome\nDroopy 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.\nMarfan syndrome\nThis 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.\nMyasthenia gravis\nDroopy eyelids and double vision can be signs of myasthenia gravis, an autoimmune condition that also causes muscle weakness.\nSkin cancer\nIf you develop a sore on or near your eyelid and have noticed that you\u2019re 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.\nThyroid disease\nEyes that protrude or bulge \u2014 a condition called exophthalmos \u2014 can be a common sign of Grave\u2019s disease, also known as an overactive thyroid gland. This \u201cbug-eyed\u201d 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.\nEarly Detection\nSome of these changes to your eyes can be treated and\u00a0possibly prevented if detected early. If you are experiencing any of these symptoms you should contact your doctor. Make an appointment at UPMC today.\nLearn more about your eye health. Visit the UPMC Eye Center webpage\u00a0for more.
