The Science Behind Diabetic Lens Data

Te human lens is a transparent, avascular structure that maintains its clarity thritig a complex osmotic environment. Glucose freepy diffuses into the aqueous humor andd is taken up by lens epibhelial cells via insulin- independent transporters (GLUT1 andGLUT3). FLT: 1 XI.1; FLT: 0 X3; Prolonged hyperglycemia couses sorbitol acculation with in lens cells, leading to osmotic stress and reversiblins lens hydration, curvatare, and opticai.

Studies haves demonstrantate a strong correlation between average lens density measured by OCT and HbA1c levels over the precedeng g 2- 3 months, while real- time flucations in lens hydration have been shown to track acute changes in blood glucose with a lag time of only 15- 30 minutes. Tis dual- time- scale signal - both chronic and acute - makees lens data unique valuable for requiling both basal and bolus politin doses sene settle settine.
