National Diabetes Outcomes Quality Review Initiative (NDOQRIN) data dictionary


An ophthalmologist is a physician specialising in diagnosing and prescribing treatment for defects, injuries and diseases of the eye, and who is skilled at delicate eye surgery.

Patients with diabetes have increased risk of developing several eye complications including retinopathy, cataract and glaucoma that may lead to loss of vision.

Regular eye checkup is important for patients suffering from diabetes mellitus. This helps to detect abnormalities early and to avoid or postpone complications.
