Diabetic Retinopathy

What is Diabetic Retinopathy?

Diabetic retinopathy occurs when the tiny blood vessels inside the retina at the back of the eye are damaged as a result of diabetes. This can seriously affect vision and in some cases cause blindness.

These images give an impression of what someone with diabetic retinopathy may see compared to someone with normal vision.
