Have you ever wondered why your eye care provider spends so much time carefully examining your eyes? Although they are looking for diseases or conditions that can affect your vision during eye exams, he or she is also searching for signs that may indicate that you have a general health problem. These eight diseases often cause symptoms that can be seen in your eyes.
When your blood sugar is high for a long period of time, the small blood vessels in your retina may begin to leak, causing a condition called diabetic retinopathy. The retina lines the back of your eye and sends light signals to the brain, where they're interpreted as images. When your vessels leak blood or fluid, your vision can become blurred, and you may lose central vision or the ability to see colors. If diabetic retinopathy progresses, new blood vessels form in the retina, worsening vision problems. Prompt treatment of diabetic retinopathy helps prevent permanent damage to your vision.
Cataracts, a condition that occurs when the clear lens inside your eye becomes cloudy, can be another clue that you may have diabetes. People who have diabetes are 60 percent more likely to develop the condition than those who don't, according to the American Diabetes Association. Cataracts may also appear at a younger age and progress more rapidly if you have diabetes.
High cholesterol occurs when a fatty substance called plaque narrows your arteries, increasing your risk for heart disease and heart attacks. In some cases, fat deposits form a partial or full white ring around the edge of your corneas. The deposits, common in older people, can be a sign of cholesterol problem if you're under 40.
Iritis, an inflammation of the iris, may be more likely to occur if you have ankylosing spondylitis, an inflammatory form of arthritis. Pain often starts in the lower back but can eventually spread to your neck, hips, ribs, shoulders and heels as the disease progresses. If you have iritis, your eye may be painful, red and very sensitive to light.
Yellow eyes or skin can be a sign of jaundice, a condition that occurs when your liver produces too much bilirubin in response to inflammation or damage. Damage can occur due to viruses, autoimmune disorders, genetic diseases or alcohol abuse.
Sickle Cell Disease
Sickle-shaped blood cells block vessels, causing severe pain, anemia and fatigue if you have sickle cell disease. The blood vessels in the eyes can also be affected by the disease. Common eye symptoms of sickle cell disease include eye pain and redness, peripheral vision loss, blurry vision, floaters and jaundice. Blockage of the blood vessels in the retina may lead to a hemorrhage of the retina or vitreous, the clear gel that gives the eye its shape. It's important to see your eye care professional as soon as possible if you have sickle cell disease and notice changes in your vision.
Drooping eyelids are the first symptom of myasthenia gravis for 50 percent of people who develop the autoimmune disorder, according to Brigham and Women's Hospital. The disorder attacks and weakens the muscles in your body under your control, such as those in your arms and legs. If you have myasthenia gravis, you may find it hard to walk or hold your head upright. The condition can also affect your ability to chew, speak and breathe.
It makes sense that blood vessels in the eye would be just as affected as vessels in other parts of your body if you have heart disease. Minor changes to the vessels in your retina, such as swelling or narrowing, or swelling of the base of the optic nerve, may mean that you're at risk of developing heart disease. Luckily, once you know that you have risk factors for heart disease, you can make diet and lifestyle changes to reduce your risk.
Brain and Nerve Conditions
Eye twitches often occur if you're tired, stressed, or if your eye is irritated. Although most eye twitches aren't serious, the symptom can sometimes be a sign of a brain or nerve condition, such as Bell's palsy, Parkinson's disease or multiple sclerosis.
