Diabetic retinopathy (DR) is still one of the commonest causes of visual loss in the Western world in the working age population.

Patients with visual loss due to DR often reflect late presentation or non-attendance to diabetes and eye services.

The pattern of blindness in diabetes is that maculopathy is the major cause, particularly in type 2 diabetic subjects, whereas blindness due to proliferative retinopathy is becoming rarer in type 1 diabetes.

DR meets the screening criteria of Wilson and Jungner for a successful programme; as it has important adverse effects, laser treatment is effective, it can be easily detected by digital photography, which is an acceptable test, and is cost-effective.
