Genetic Susceptibility to the Development of Retinopathy in Insulin-dependent Diabetics

HLA types and blood glucose control were investigated in 127 insulin-dependent diabetics with different grades of severity of retinopathy. The means of all afternoon clinic blood glucose levels from the diagnosis of diabetes were 9.9 ± 2.1 mmol/L for patients with no retinopathy, 11.8 ± 2.1 mmol/L for patients with background retinopathy, and 12.4 ± 2.1 mmol/L for patients with proliferative retinopathy (P
