INS and Insulin resistance: The overall pattern suggested that markers of glucose tolerance (e.g. fasting glucose, AUCGlucose as assessed by the trapezoidal rule [22]) and insulin resistance (e.g. HOMA2-IR, TyG index) were mostly negatively, whereas different indices of insulin sensitivity (e.g. eGDR, Stumvoll MCR) were mostly positively, related to global retinal thicknesses of the different retinal bands, referring to a global retinal thinning when adverse glucose homeostasis is present.
