People with severe non proliferative diabetic retinopathy have a high risk of developing PDP and may need a comprehensive dilated eye exam as often as every 2 to 4 months. In other cases, abnormal new blood vessels grow on the surface of the retina. adults, diabetes nearly doubles the risk of glaucoma.
