Abstract
Diabetic retinopathy is a major cause of preventable sight loss in the working-age population and a major global health issue. It is caused by chronic hyperglycaemia, which also predisposes patients with diabetes mellitus to a range of other ocular complications including diabetic macular oedema, eye infections, diabetic cataract, and dry eye and corneal complications. Ocular complications of diabetes can significantly affect people's quality of life, so regular eye screening from the point of diabetes diagnosis, as well as a multidisciplinary team approach, are required to identify these complications early, manage them effectively, and support patients to achieve glycaemic control. This article provides an overview of diabetic retinopathy and other ocular complications of diabetes, and explains the role of the nurse in providing health promotion, patient education and support.
