What is proliferative diabetic retinopathy (PDR)?

ANSWER

If you continue to have high blood sugar over several years, you could go on to have a more severe eye disease known as proliferative diabetic retinopathy. It's called "proliferative" because new blood vessels start to grow on the surface of the retina. These blood vessels are fragile and can leak blood or fluid. This causes scarring of the retina and long-term vision loss.
