Diabetic Retinopathy Review of Diabetic Retinopathy Screening Methods and Programmes Adopted in Different Parts of the World Janusz Pieczynski, 1,2 and Andrzej Grzybowski 1,3 1. Chair of Ophthalmology, University of Warmia and Mazury, Olsztyn, Warszawska, Poland; 2. The Voivodal Specialistic Hospital, Olsztyn, Zolnierska, Poland; 3. Department of Ophthalmology, Poznan City Hospital, Poznan, Poland Abstract Introduction: One of most common diabetic complications is diabetic retinopathy (DR). Sight-threatening DR can be avoided when diagnosed early and treated in a timely fashion. The aim of this study is to review current worldwide DR screening programmes and studies. Methods: A PubMed platform search was performed to find clinical trials or studies of current DR screening methods. Results: Direct and indirect ophthalmoscopy is still used, but digital photography of the retina seems to be the most efficient, objective and cost-effective. Conclusions: DR screening programmes are developed all over the world. They help to detect early sight-threatening DR, treat it in a timely fashion and in this fashion help to avoid expensive, advanced treatment or even prevent to develop blindness among working age people.

E: janusz.pieczynski@op.pl Diabetes mellitus (DM) is a growing socio-medical problem because of its increasing prevalence and diabetic complication rate. This is also the reason for the large amount of money spent on diabetes treatment and on diabetic complications despite continually improving diabetes care. 1,2 The International Diabetes Federation’s latest study has shown the number of people with diabetes rise from 382 million worldwide in 2013 to 592 million in 2035. 3 One of most common microvascular diabetic complications is diabetic retinopathy (DR). It is a most common reason for blindness in developed countries. Sight-threatening DR can be avoided when identified early and cured in a timely fashion. 4–7 This is the reason for diabetic screening implementation. Rules of screening in medicine were established by Wilson and Jungner in 1968 and accepted by the World Health Organization (WHO). 8 The • There should be an agreed policy on whom to treat as patients. • The cost of case finding (including diagnosis and treatment of patients diagnosed) should be economically balanced in relation to possible expenditure on medical care as a whole. • Case finding should be a continuing process and not a ‘once and for all’ project. These rules could be adapted for DR screening. The first attempts were made in 1989, when the St Vincent Declaration was made. According to this declaration, reduction of blindness due to DR by one-third in the following 5 years was planned. 9 The next attempts on DR blindness reduction were established in 2005 in the Liverpool Declaration. 10 The consensus was to reduce blindness due to DR by 2010, by DR systematic screening covering at least 80 % of the people with diabetes population with the use of trained personnel and access to the proper therapy. basic principles for disease screening were as following: Aim of Study • The condition sought should be an important health problem. • There should be an accepted treatment for patients with recognised disease. • Facilities for diagnosis and treatment should be available. • There should be a recognisable latent or early symptomatic stage. • There should be a suitable test or examination. • The test should be acceptable to the population. • The natural history of the condition, including development from latent to declared disease, should be adequately understood. Tou ch MEd ica l MEdia The aim of this study is to review current worldwide DR screening programmes and studies performed by technicians or primary care physicians (not ophthalmologists), quickly and simply. Methods This is a review study. A PubMed platform search was performed, using the following keywords: diabetic retinopathy screening programme, telemedicine and DR, prevented diabetic vision lost to find clinical trials or review studies of current DR screening programmes.
