Corneal infiltrating cells and nerve fiber parameters in participants with chronic inflammatory demyelinating polyneuropathy (CIDP) or diabetes. Corneal cellular infiltrates were classified as dendritic cells (without [DCP] or with [DCF] fiber contact) or non-dendritic cells (without [NCP] or with [NCF] fiber contact) in participants with CIDP, diabetes and control participants a–d. Corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD), and corneal nerve fiber length (CNFL) were quantified e–g. The number of infiltrating cells with proximity to nerve fibers h, the number of cells without nerve fiber contact i, and the total corneal cell count j were determined. Mean ± SEM, *P < 0.05, **P < 0.01, ***P < 0.001, ns indicates not significant
