糖尿病神経障害の早期スクリーニングに向けた可視光から近赤外光までの足裏の吸光度計測

抄録

In this study, we investigated whether there is a difference in the absorbance of foot soles between diabetic patients and healthy subjects by irradiating visible and near infrared rays. We measured the absorbance of the big toe, first metatarsal skin and the heel using a probe and confirmed significant differences at 540nm to 580 nm, 1200nm to 1400 nm, and 1600 nm to 1800 nm. 580 nm is a wavelength at which hemoglobin in blood is easily absorbed, and the significant difference seems to be due to the decrease in the number of capillaries in the patient. The significant difference at 1400 nm may be due to dry feet of the patient. The significant difference between 1600nm and 1800nm may be due to blood glucose.
