title: Emerging strategies for the prevention and treatment of diabetic eye disease.
abstract: Diabetic retinopathy (DR) is the major cause of blindness in the working age groups of industrialized countries, and a programme has been launched by the World Health Organization (WHO) and the International Diabetes Federation (IDF) to reduce its morbidity in Europe. Retinopathy progresses slowly, and even when it becomes sight-threatening, may not present visual symptoms. When symptoms do occur, it is often too late to restore full vision or to stop further deterioration by retinal photocoagulation. For photocoagulation to be maximally effective, treatable sight-threatening retinopathy must be identified while still asymptomatic by means of regular fundus examination of all diabetic patients. Given the absence of effective medical treatment, prevention of retinopathy depends on mass screening. The WHO and IDF recommend that internists in charge of diabetic patients perform a fundus examination at least every two years if retinopathy is absent, or as frequently as necessary otherwise. Patients at risk should be referred for assessment and treatment to ophthalmic facilities. Either direct ophthalmoscopy or retinal photography are suitable methods. The setting up of nation-wide screening programmes is essential for coordinated action. Pilot studies have proven that screening is an effective means for decreasing diabetes related blindness and the human and social costs attached to it.
