How many stages of diabetic retinopathy are there?
1. Non-proliferative (NPDR) stage
This is the initial stage where patients usually do not feel any abnormalities. When examining the eyes, there may be bleeding spots on the retina indicating that there is fluid leakage from blood vessels, causing retinal swelling and the beginning of slight blurred vision. However, if the area of the clear vision has swelling (macular edema) or ischemia, it results in loss of vision.
2. Proliferative Diabetic Retinopathy (PDR)
In the more severe stage, neovascularization occurs due to severe ischemia. These blood vessels are often fragile and rupture easily, causing bleeding into the vitreous humor and forming a traction fibrosis that pulls the retina. During this stage, vision often deteriorates significantly and permanent vision loss may occur.
Or if the new blood vessels that occur interfere with the drainage of water from the eye, it will result in increased eye pressure, causing damage to the nerves that transmit images from the eye to the brain, which will also cause glaucoma.

What is Diabetic Retinopathy?
Diabetic retinopathy, the most common diabetic eye disease, occurs when high blood sugar levels damage blood vessels in the retina. There are two types : Background (or non-proliferative) and proliferative. Background (BDR), is an early stage.
