Proliferative---The retina sends signals so new blood vessels are created. These blood vessels are abnormal and more likely to hemorrhage due to the thin walls of the vessel. The walls of these vessels are weak and soon begin to hemorrhage.
Diabetic Retinopathy is caused when chronic high blood sugar damages the small blood vessels nourishing the retina. This will eventually affect both eyes . (National Eye Institute 2003)
In the latest stage of diabetic retinopathy, vision loss is characterized by blurriness, spots, and sometimes blindness. (National Eye Institute, 2003)
