People with diabetes can have an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell and leak. Or they can close, stopping blood from passing through. Sometimes abnormal new blood vessels grow on the retina. All of these changes can steal your vision.

Diabetic Retinopathy Symptoms

You can have diabetic retinopathy and not know it. This is because it often has no symptoms in its early stages. As diabetic retinopathy gets worse, you will notice symptoms such as:

  • seeing an increasing number of floaters,
  • having blurry vision,
  • having vision that changes sometimes from blurry to clear,
  • seeing blank or dark areas in your field of vision,
  • having poor night vision, and
  • noticing colors appear faded or washed out losing vision.

Diabetic retinopathy symptoms usually affect both eyes.
