Causes of Diabetic Retinopathy

Causes of Diabetic Retinopathy

Generally, diabetics don't develop diabetic retinopathy until they have had the disease for at least 10 years. As soon as you've been diagnosed with diabetes, you need to have a dilated eye exam at least once a year.

In the retina, high blood sugar can damage blood vessels that can leak fluid or bleed. This causes the retina to swell and form deposits. This is an early form of diabetic retinopathy called non-proliferative or background retinopathy.

In a later stage, called proliferative retinopathy, new blood vessels grow on the surface of the retina. These new blood vessels can lead to serious vision problems because they can break and bleed into the vitreous, the clear, jelly-like substance that fills the interior of the eye. Proliferative retinopathy is a much more serious form of the disease and can lead to blindness.

Fortunately, you can significantly reduce your risk of developing diabetic retinopathy by using common sense and taking good care of yourself:

  • Keep your blood sugar under good control.
  • Maintain a healthy diet.
  • Exercise regularly.
  • Follow your doctor's instructions to the letter.
