Diabetes is a condition where your body has high levels of sugar (glucose) in the blood. Over time, high blood sugar can damage many parts of the body, including the eyes. Your eyes contain tiny, delicate blood vessels, especially in the retina, the light-sensitive layer at the back of the eye. When blood sugar stays high for long periods, it can: 1. Weaken blood vessels 2. Cause them to swell or leak 3. Block blood flow to the retina 4. Trigger new, abnormal blood vessel growth (which are weak and break easily) All of this can affect your vision — sometimes permanently if left untreated. Symptoms to Watch Out For Even though diabetic eye disease may not cause symptoms in early stages, here are signs that something could be wrong: • Blurred or double vision • Dark or empty spots in your vision • Trouble seeing at night • Eye pain or pressure • Sudden loss of vision This can lead to: • Blurry vision • Diabetic Retinopathy (bleeding and swelling in the retina) • Cataracts (cloudy lens) • Glaucoma (eye pressure that damages vision)
