Diabetic RetinaScreen, the national diabetic retinopathy screening programme, operates a national call, re-call population screening programme. No referrals are required. This mirrors the approach taken with other population based screening programmes, BreastCheck, CervicalCheck and BowelScreen. Diabetic RetinaScreen provides a facility to all GPs whereby they can register their patient with the programme once a diagnosis of diabetes has been confirmed and also obtained their patient’s consent to register with the programme. Health professionals can also check if their existing diabetic patients are on the diabetic retinopathy register. Registration is currently undertaken by calling Freephone 1800 45 45 55. This will shortly be supplemented by an on-line registration facility.
