Eyes (Retinopathy)

Rationale for New Eye Complication and Eye Screening for all Adults with Diabetes

Diabetic retinopathy is the leading cause of preventable blindness in the working age population in the UK.
The risk of visual loss can be reduced by early detection and effective treatment of diabetic retinopathy.
The key role of diabetic retinal screening is to pick up patients with eye sight threatening retinopathy and offer treatment in a timely fashion.
The risk of developing diabetic retinopathy can be reduced substantially by optimising glycaemic control.
Where diabetic retinopathy is already present, glycaemic and blood pressure control still has a key role in slowing further progression.

Eye Screening

Diabetes can cause problems with the eyes and so a regular examination called a retinal examination is required for all people with diabetes mellitus.
From 2006, all retinal eye screening will be done by digital retinal photography. This will involve mobile screening vans attending GP surgeries at regular intervals. A central call and re-call system will provide appointments
Eye screening should be carried out at least yearly and commonly more frequent checks are necessary to monitor changes in the condition of the eyes.
Digital retinal photography is unnecessary if patient is already attending the Eye Department for their diabetes but is still required if attending for Glaucoma.
At annual reviews ask if the patient is up to date with their eye screening and to offer advice if they are experiencing sight problems.

Who to screen

All people with diabetes older than 11 years, or if younger if they have had diabetes 5 or more years.
Patients who are unable or unwilling to have laser treatment can be excluded from routine screening

How to screen

How often to screen

Annually if no retinopathy or background retinopathy
Review by ophthalmologist if preproliferative retinopathy, proliferative retinopathy, advanced diabetic eye disease or maculopathy
Referral guidance for retinopathy can be found on the diabetic eye examination form

Screening during pregnancy
