It is important that everyone with diabetes get an annual comprehensive dilated eye examination, according to the American Optometric Association. One of the potential complications of a diabetic’s inability to control blood sugar involves damage to the tiny blood vessels that nourish the retina. “Diabetic retinopathy” involves leakage of blood and other fluids at the back of the inner eye, which can lead to blurred vision, floaters, darkened central vision, and even blindness if left untreated. Moreover, recent research indicates that retinopathy increases the risk of memory loss and decreased thinking ability as a diabetic ages. Thus, retinopathy may provide important clues that blood vessels inside the brain are not working properly. An annual eye exam may prove invaluable. If you have diabetes, your body does not use and store sugar properly. High blood-sugar levels can damage blood vessels in the retina, the nerve layer at the back of the eye that senses light and helps to send images to the brain. Diabetic retinopathy, the leading cause of blindness among adults, may also contribute to memory loss. Diabetics can prevent or slow the development of diabetic retinopathy by taking their prescribed medication.
