Corneal Subbasal Nerve Plexus Changes in Severe Diabetic Charcot Foot Deformity: A Pilot Study in Search for a DNOAP Biomarker

Table 2

Average weighted corneal nerve fibre thickness (CNFTh), measured as mean thickness perpendicular to the nerve fibre course (μm) and average weighted corneal nerve fibre tortuosity (CNFTo), reflecting variability of nerve fibre directions, defined as total absolute nerve fibre curvature in both groups.
