What Causes it?

Retinopathy is strongly related to duration of diabetes. Nearly all individuals with type 1 diabetes-which generally strikes in childhood-develop some degree of retinopathy within 20 years of diabetes diagnosis, as do more than 60 percent of those with type 2 diabetes.
Poor blood glucose control is a significant and modifiable risk factor for development and progression of diabetic retinopathy.
High blood pressure, high blood lipids, and pregnancy are other factors associated with development and progression of diabetic retinopathy.
