POOR CONCORDANCE BETWEEN NON-INVASIVE AND LOCALLY INVASIVE TECHNIQUES OF EVALUATION OF MICROVASCULAR MORPHOLOGY IN THE DETECTION OF HYPERTROPHIC REMODELING OF SMALL RESISTANCE ARTERIES

Objective: The evaluation of the morphological characteristics of small resistance arteries in human beings is not easy. The gold standard is generally considered to be the evaluation of the media to lumen ratio (MLR) of subcutaneous small vessels obtained by local biopsies and evaluated by wire or pressure micromyiography. However, non-invasive techniques for the evaluation of retinal arterioles were recently proposed, in particular two...
