Diabetic Eye Screening

Why diabetic screening is done

If you have diabetes you may be at risk of developing eye problems called diabetic retinopathy. Diabetic retinopathy can cause sight loss if it's not treated.

Diabetic eye screening checks your eyes for problems, often before you notice any changes in your sight. Finding and treating diabetic retinopathy early can reduce and prevent damage to your eyes and sight loss.

How to get diabetic eye screening

The letter inviting you for diabetic eye screening will tell you how to book the test.

The photographs of your eye will be sent to an expert to be reviewed.
