Retinopathy is associated with higher glycaemia in maturity-onset type diabetes

Abstract

In a group of 149 maturity-onset type diabetic patients followed from diagnosis, 55 (37%) had retinopathy on colour photography 7 years later. Those patients with retinopathy had significantly greater glycaemia, as shown by higher fasting plasma glucose levels at diagnosis, larger mean values for fasting glucose 1, 3 and 5 years later, and higher random glucose and haemoglobin A1c at ophthalmic review (p = 0.001, 0.002, 0.007 and 0.001, respectively). Substantial retinopathy, as measured by greater than 5 microaneurysms, also correlated significantly with each index of glycaemic control.
