Diabetic retinopathy (DR) is a usual chronic microvascular complication which occurs in diabetes. DR causes gradual visual impairment and is a typical cause of sightlessness in the EU. Neovascularization and vitreal hemorrhage are present in proliferative DR. Ophthalmoscopy, OCT, FA, digital retinography and OCTA are used in diagnostics. Anti-angiogenic and laser therapy are most often used as treatment. In screening for DR, retinal photography is considered the gold standard, which allows images to be stored on a computer. It is considered that the best interval between eye examinations is one or two years. It is essential to introduce digital technologies and artificial intelligence into screening. In Sweden, there is screening for DR at the local level. Hungary has designed a program to raise life quality in patients with diabetes using a mobile van containing digital retinal camera. In Ireland, a biomicroscope is used as part of screening. Denmark has established a Registry for DR called Diabase which automatically electronically registers all examination data. In Portugal, 5 regions carry out a screening program separately. Telemedicine projects have been introduced in Finland and Norway to facilitate access to screening. Slovenia has introduced DR screening since 2010. England has been running a national screening program since 2004. Scotland has introduced a national screening program since 2003, and an automated system for reading digital retinography images has also been introduced. The screening for DR plays a crucial role in preventing and stopping the progression of DR, thereby reducing the incidence of blindness in diabetic patients. The aim of this work is to bring the possibilities and benefits of DR screening to wider academic community in order to improve the health of patients with diabetes.
