Diabetic Eye Disease: How High Blood Sugar Affects Your Vision

Protecting Your Sight When You Have Diabetes

If you have diabetes, you are likely used to monitoring your blood sugar, diet, and feet. But did you know that diabetes is one of the leading causes of preventable blindness in adults? Diabetic Eye Disease refers to a group of eye problems that people with diabetes may face as a complication of the disease.

Understanding Diabetic Retinopathy

The most common and severe condition is Diabetic Retinopathy. Chronically high blood sugar damages the tiny blood vessels in the retina (the light-sensitive tissue at the back of the eye). These vessels can swell, leak fluid, or close off completely. In advanced stages, abnormal new blood vessels grow on the surface of the retina, which can bleed and cause severe vision loss.

The Danger of the "Silent" Symptoms

In its early stages, diabetic eye disease often has no warning signs or pain. By the time you notice symptoms like blurry vision, floating spots (floaters), or dark areas in your field of vision, severe damage may have already occurred. This is why waiting for symptoms is dangerous.

Proactive Care and Prevention

• The Annual Dilated Exam: This is your strongest defense. A comprehensive dilated eye exam allows your ophthalmologist to see deep into the eye and catch vessel damage before it affects your sight.
• Manage the ABCs: Strictly control your A1C (blood sugar over time), Blood pressure, and Cholesterol. High blood pressure greatly accelerates retinal damage.
• Advanced Treatments: If caught early, treatments like anti-VEGF injections or laser surgery can stop the progression of the disease and save your vision.
