Eye Complications (Retinopathy)


The retina is light- sensitive tissue of the eye. Retinopathy (damage to eye) occurs when diabetes damages the tiny blood vessels in the retina. This damage can lead to problems with your vision including blindness.

High blood sugar levels damage small blood vessels. The weakened blood vessels may break and leak fluid and blood. Also, new abnormal blood vessels may grow. These new blood vessels can bleed, cause cloudy vision, and destroy the retina.


Diabetic retinopathy begins before you have any symptoms. As the problem gets worse, you may have:
  • Blurred vision
  • Floaters, which are black spots or cobweb like shapes
  • Temporary or permanent blindness.

How to prevent retinopathy?

  • Maintain tight control of blood glucose , blood pressure and cholesterol levels
  • Get a complete eye check up done by an eye specialist shortly after the diagnosis and once a year thereafter.
  • Stop smoking

ADA recommends comprehensive eye examination by an ophthalmologist shortly after the diagnosis of diabetes and once a year thereafter.
