Diabetic retinopathy (DR) is a significant microvascular complication of diabetes. High quality interdisciplinary collaboration is an important aspect ofa successful DR therapy. A case ofa 41-year-old diabetic is presented below, who has been in our care for almost four years. His Diabetes ID card only contains his current glycaemia values. Although the patient had been regularly given a report for his diabetologist with a request for additional information, we have only obtained one value of glycated haemoglobin through the course of the patient's dispensarisation. For this reason, and the non-stabilisation of DR, we have recommended that the patient starts to see a different diabetologist.
