Diabetic retinopathy is a common eye condition affecting people with diabetes, caused by prolonged high blood sugar levels that damage the tiny blood vessels of the retina. Over time, these blood vessels may weaken, swell, or leak, reducing the retina’s ability to function properly. In some cases, blood flow to parts of the retina may be blocked, leading to vision impairment.
As the condition progresses, abnormal new blood vessels can develop on the surface of the retina, increasing the risk of bleeding, retinal damage, and vision loss. Early stages often show no noticeable symptoms, which is why regular eye examinations are essential for people with diabetes. Early diagnosis and timely treatment play a key role in preserving vision.
