However, this condition can cause blindness. The fact is that this condition affects up to 80 percent of people who have diabetes for 10 years or more and every year in the United States, diabetic retinopathy is responsible for 12 percent of all new cases of blindness.
Diabetic retinopathy develops through various stages and as in most conditions, the earlier it is diagnosed, the better the prognosis for recovery.
