[Significance of elevated hemoglobulin A1c for the pathogenesis of diabetic retinopathy]
The hemoglobin of 70 diabetics with retinopathy was analysed. 56 patients had pathologically elevated values, 12 values were within the upper normal limit and in 2 cases the findings were normal. This hemoglobin variant is characterized by an increased affinity of oxygen. Clinically and pathologically speaking the elevated HbA1c value could be a causal factor in diabetic retinopathy. Comparisons with sickle cell anemia and thalassemia seem to indicate that hemoglobinopathy and retinopathy are pathogenetically related.
