Review of Diabetic Retinopathy Screening Methods and Programmes Adopted in Different Parts of the World

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.
