Understanding Diabetic Retinopathy: Causes, Symptoms, and Management
Diabetic retinopathy is a serious eye condition that affects people living with diabetes. It occurs when high blood sugar levels cause damage to the blood vessels in the retina, the light-sensitive tissue at the back of the eye. Over time, this damage can lead to vision impairment and, in severe cases, blindness. Early detection and proper management are essential to preserving vision and preventing complications.
The condition often develops silently, with many individuals unaware they have any issues until vision problems become noticeable. There are two primary stages of diabetic retinopathy: non-proliferative and proliferative. Non-proliferative diabetic retinopathy (NPDR) is the early stage, where blood vessels may weaken and leak fluid into the retina. Swelling of the retina, particularly in the macula—the area responsible for sharp vision—can occur, resulting in blurry or distorted vision.
If left untreated, NPDR can progress to proliferative diabetic retinopathy…
