[HbA1 as a parameter of the progression of diabetic retinopathy].
HbA1 was determined in 12 juvenile diabetics with diabetic retinopathy and in ten adult diabetics at four-weekly intervals. During this time the course of the retinopathy was observed. Retinopathy was constant in juvenile diabetics with HbA1 values below 8%. A moderate progression, which it was possible to slow down by laser treatment, was observed in patients with HbA1 values of between 8% and 10%. Patients with HbA1 values exceeding 10% showed a marked progression, which could not be stopped by intensive laser therapy. The behavior of the retinopathy in adult diabetics corresponded to that of the juveniles when the onset of the disease was between the ages of 30 and 50. In elderly diabetics no significant tendency was observed.
