Lens Fluorescence in Relation to Metabolic Control of Insulin-Dependent Diabetes Mellitus

Abstract

• The correlation of blue-green lens fluorescence to the metabolic control of insulin-dependent diabetes mellitus was studied in 36 patients in whom the level of glycosylated hemoglobin A_1c (HbA_1c) had been followed from the onset of diabetes. Good metabolic control (22 patients, all with mean HbA_1c levels, 9.7%). It appears that in diabetes, an increase in lens fluorescence and a decrease in lens transmittance are delayed by good metabolic control, and that the determination of lens fluorescence provides information about the long-term control of diabetes.
