Diabetic Retinopathy

Diabetic retinopathy is the most common diabetic eye disease and one of the foremost causes of blindness in adults under the age of 65. This is caused by changes in the blood vessels of the retina.


Symptoms of diabetic retinopathy include:

  • discoloured spots (known as floaters that ‘float’ in your field of vision
  • blurred vision
  • your vision becomes blocked by patches or streaks
  • reduced night vision
  • sudden vision loss


In some people with diabetic retinopathy, blood vessels may swell and leak fluid. In other people, abnormal new blood vessels grow on the surface of the retina. The retina is the light-sensitive tissue at the back of the eye. A healthy retina is necessary for good vision.


At first it may not cause noticeable changes to the vision. But over time, diabetic retinopathy can get worse and cause vision loss. Diabetic retinopathy usually affects both eyes. An annual eye examination is necessary for all diabetic patients to reduce the chance of contracting diabetic retinopathy.
