Diabetic retinopathy is a complication of diabetes that occurs when poorly controlled blood sugar damages blood vessels in a part of the eye called the retina. Proliferative diabetic retinopathy (PDR) is one of the most severe types. PDR happens when abnormal blood vessels begin to grow in the retina, causing bleeding, scarring and vision loss.1

The longer you have diabetes, the more likely you are to develop PDR. However, large studies have shown you are less likely to develop PDR if you have controlled:2

  • Blood sugar levels
  • Cholesterol levels
  • Blood pressure

Regular eye checks are important for all diabetic patients, so signs of retinopathy can be detected and treated early. It’s important to tell your doctor immediately if you notice any changes in your vision.1
