Diabetic Retinopathyis caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye, the retina.
Types of diabetic retinopathy
- Nonproliferative stage occurs in the beginning stages of diabetic retinopathy; blood vessels in the retina are weakened and may leak fluid
- Proliferative is a more advanced form of the disease causing abnormal blood vessels to grow in the retina; also causes circulation problems that deprive the retina of oxygen Macula Edema happens when fluid builds up (usually leakage from blood vessels that are damaged) in the macula, causing swelling. This can distort vision, making things look blurry and colors look washed out.
Treatment: How retinopathy is treated depends on the type and severity and is geared to slowing or stopping the progression of the condition.
