Diabetes affects your body from head to toes. This includes your eyes. The most common and most serious eye complication of diabetes is diabetic retinopathy, which may result in poor vision or even blindness.
“Retinopathy” is the medical term for damage to the tiny blood vessels (capillaries) that nourish the retina, the tissue at the back of your eye that captures light and relays information to your brain. These blood vessels are often affected by the high blood sugar levels associated with diabetes.
Nearly half of people with known diabetes have some degree of diabetic retinopathy. The longer you have diabetes, the more likely it is you’ll develop diabetic retinopathy. Initially, most people with diabetic retinopathy experience only mild vision problems. But the condition can worsen and threaten your vision.
The threat of blindness is scary. But with early detection and treatment, the risk of severe vision loss from diabetic retinopathy is small. You can take steps to protect your sight if you have diabetes. These include a yearly eye examination and steps to keep your blood sugar, blood pressure and blood cholesterol under the best possible control.
Diabetic retinopathy is caused by damage of the blood vessels in the retina. Nonproliferative diabetic retinopathy develops first when the vessels in the eye become larger in certain spots. Proliferative diabetic retinopathy is the advanced form of the disease where new blood vessels start to grow in the eye.
Diabetic Retinopathy is caused due to diabetes problems that inadvertently affect the eye at a certain stage. Diabetes eye problem that requires treatment if some or more of the symptoms occur: blurry or double vision, dark or blank spots, pain or pressure in eyes and trouble seeing from the corner of the eyes.
