Retinal fundus photo screening has become the preferred means of detecting diabetic retinopathy. Grader External Quality Assurance (EQA) is necessary to inform Graders of areas that they need to work on to improve their grading skill. This video is intended as a performance enhancing tool for graders who will participate in the Scottish EQA. The video discusses the EQA interface, features of diabetic retinopathy (DR) and provides tips. DR has been identified as a key biomarker for systemic disease, particularly coronary heart disease and stroke. We are now not only "screening for sight", but also "screening for life". All people affected by or dealing with the diabetic epidemic will find this interesting.
