How is DR treated?

In the early stages, DR can be managed by controlling blood sugar levels and blood pressure. However, as DR progresses, options to maintain vision include anti-VEGF injections, laser treatment or surgery. Early detection of diabetic retinopathy is crucial, as treatment is much more likely to be successful at an early stage.

How can DR be prevented?

  • Monitor and maintain control of your diabetes.
  • See your doctor regularly and follow instructions about diet, exercise and medication.
  • See your optometrist for a thorough eye examination when you are first diagnosed with diabetes, and annually thereafter.
