Our eyes can reveal a lot about us, you can say that they are not just the window to our soul but also to our health. Not only can you see signs of conditions like high cholesterol and diabetes, but doctors can also identify signs of a few other diseases. According to the American Academy of Ophthalmology, doctors can spot signs of heart disease during a regular eye exam. They also explain how studies have found that people with heart disease often have tiny "eye strokes" in their retinas.Also Read: Spike In ‘Gas Station Heroin’ Use Sparks National Health Warning Harvard Health Publishing adds that sudden changes in your vision, like blurriness, dark spots, or shadows, could mean there's a blockage in an eye blood vessel. This can be a warning sign of a more serious stroke in your brain. Also, there's growing evidence that tiny, early damage to blood vessels in your eyes might predict heart problems. Other unusual eye changes can also hint at heart issues, like small yellow bumps around your eyes, or pupils that get bigger and smaller with your heartbeat. How Your Eyes Reveal Heart Disease Risk?Tiny blood vessels, as thin as a single strand of hair, supply blood to your retina. Harvard Health Publishing also explains that these tiny vessels, like arteries throughout your body, can be damaged by long-term problems like diabetes and high blood pressure. Over time, high blood sugar, which is diabetes, makes the walls of these eye vessels weak and leaky. This condition is called diabetic retinopathy and can harm your vision. Poorly controlled high blood pressure can also make eye arteries narrow or break and bleed into the retina. Both diabetes and high blood pressure are known to contribute to heart disease. But sometimes people don't even know they have these conditions if they haven't seen a doctor in years.Also Read: Lethal Fungus Is Spreading Across Many US States, Why Is It Concerning? Yellow Bumps Around the Eyes Harvard Health Publishing also specifies that some adults, usually middle-aged or older, develop soft, yellowish bumps filled with cholesterol on or around their eyelids, often near the nose. These are called xanthelasmas. They don't hurt and rarely affect vision. But they can be a sign of high levels of cholesterol or other fats in the blood. They're a bit more common in women. If you have them, you should definitely get a cholesterol test. Xanthelasmas are more common in people with genetic conditions that cause very high cholesterol. About half of people with xanthelasmas have normal cholesterol levels, and for them, the bumps are just a cosmetic issue. But if heart disease runs in your family, make sure your doctor knows about these bumps, as they could be a sign of a higher risk of heart problems. What Are Eye Strokes? Eye strokes happen when the eye doesn't get enough blood and oxygen, causing some cells to die. This leaves a small mark called a "retinal ischemic perivascular lesion." Eye doctors can see these marks using a special camera called an OCT (optical coherence tomography) to look closely at the back of your eye. American Academy of Ophthalmology says these eye scans are great for finding problems all over the body, not just in the eyes. They can even show signs of diseases like Alzheimer's and Parkinson's. Rare Occurrence of Pupil That Pulsates with Your Heartbeat Harvard Health also brings up a rare yet obvious sign of heart issues that affect your eyes. In serious cases, a rare eye sign can appear: your pupils might get bigger and smaller with each heartbeat. This is called Landolfi's sign, first described in 1909. People with this heart condition have a big difference between the two numbers in their blood pressure (the top and bottom numbers). The pupil movements show these big changes in pressure. A 2017 issue of the American Journal of Medicine detailed a case study of a 60-year-old woman who was admitted with shortness of breath, lightheadedness as well as palpitations, which when checked, doctors heard a murmur. Another careful examination of the eyes revealed constriction and dilation of the pupils which synchronized with the patients' heartbeat. The study detailed how this was a sign of the “Landolfi's sign”. How An Eye Check-up Can Save You For people with heart disease, which is the leading cause of death worldwide, finding it early and getting treatment can help prevent a heart attack or a bigger stroke.In the future, if an eye doctor sees these eye strokes on a scan, they might send the patient to a heart doctor, especially if the patient hasn't had a full health checkup or doesn't know if heart disease runs in their family.
