Corneal infiltrating cells and nerve fiber parameters in participants with chronic inflammatory demyelinating polyneuropathy (CIDP) with (+), or without (−) monoclonal gammopathy of undetermined significance (MGUS). Corneal confocal microscopy was used to classify corneal cellular infiltrates 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 with (+) or without (−) MGUS, in participants with diabetes, and control individuals a–d. Corneal nerve fiber density (CNFD), corneal nerve fiber length (CNFL), and corneal nerve branch density (CNBD) were quantified e–g. Mean ± SEM, **P < 0.01, ***P < 0.001, ns indicates not significant
