Diabetic retinopathy is a serious complication of diabetes that affects the tiny blood vessels in the retina. High blood sugar levels can damage these vessels over time, leading to leakage, swelling, or abnormal blood vessel growth. If not treated promptly, this condition can cause blurred vision, dark spots, or even permanent vision loss. https://thinkeyehospitals.blogspot.com/2025/09/preserving-vision-in-diabetes-effective.html
