NPDR (non-proliferative diabetic retinopathy)
This is the early stage of diabetic eye disease. Many people with diabetes have it.
With NPDR, tiny blood vessels leak, making the retina swell. When the macula swells, it is called macular edema. This is the most common reason why people with diabetes lose their vision.
Also with NPDR, blood vessels in the retina can close off. This is called macular ischemia . When that happens, blood cannot reach the macula. Sometimes tiny particles called exudates can form in the retina. These can affect your vision too.
If you have NPDR, your vision can be blurry or even normal.
