Eye screening for patients with diabetes – to prevent blindness

Eye screening for patients with diabetes - to prevent blindness

For those with diabetes, sight loss and blindness, is a serious risk. The Public Health Agency (PHA) is marking Diabetes Week (10–16 June 2012)  to remind those with diabetes to get tested for retinopathy – the condition which causes loss of sight in diabetes.

Diabetes is a common condition affecting over 75,0001 adults in Northern Ireland. Diabetic retinopathy is a possible complication of diabetes which can cause sight loss and blindness. Retinopathy damages the tiny blood vessels (capillaries) that nourish the retina, the part of the eye that helps us to see. 

In Northern Ireland, the PHA commissions a regional diabetic screening programme (DRSP) as research shows that if retinopathy is identified early, for example through screening, and treated appropriately, blindness can be prevented in the majority of people with diabetes, this includes both type 1 and type 2.

Dr Bernadette Cullen, Public Health Consultant, PHA, said: “Screening detects problems early and allows appropriate treatment to be offered. It is vital that everyone with diabetes attends diabetic retinopathy screening when it is offered. Early detection of potential problems offers a very real opportunity to intervene and, with appropriate treatment, can prevent blindness in the majority of those at risk.”

The PHA diabetic retinopathy screening programme is available to all eligible people with diabetes aged 12 years and over. A photograph is taken of the back of each eye. This is painless and takes about 15 minutes. If a person is over 50 years of age, they have eye drops about 15 minutes before the test, to dilate their pupils.

Once analysed by trained graders, results will show whether further assessment or treatment by hospital eye services is needed. If this is not required, screening will be offered again the following year. GPs are informed of all results and if the patient is under the care of a hospital diabetic specialist, they will also be informed. Patients are informed of results by their GP and if they need an urgent referral, protocols are in place to ensure this happens.

Many people with diabetes have a sight test for glasses. It is important they continue to do this – this test is free to people with diabetes. 

It is also vital that people with diabetes attend for diabetic retinopathy screening when invited. A patient information leaflet to support patients in making an informed decision to attend for screening is also sent. This is available in 10 different languages.
