Diabetic retinopathy is the most common form of diabetic eye disease. Retinopathy can affect all diabetes and becomes dangerous, increasing the risk of blindness if it is left untreated. Diabetic retinopathy occurs when changes in blood glucose levels cause changes in retinal blood vessels. In some cases, these vessels will swell up (macular edema) and leak fluid into the rear view of eye. In other cases, abnormal blood vessels will grow on the surface of the retina. Likewise many other condition diabetic retinopathy in early stages may have no significant symptoms and without pain. Macular edema can result from maculopathy and affect vision occurs if leaking fluid causes the macular to swell. New vessels on the retina can prompt bleeding, which can block vision in some cases. The symptoms of diabetic retinopathy in advance stage are sudden changes in vision, eye floaters and spots, double vision, eye pain. People are at high risk if affected with poor blood glucose control, protein in urine, high blood pressure, raised triglycerides in the blood.
