BACKGROUND AND OBJECTIVES: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an autoimmune disease primarily affecting the peripheral nervous system. However, several noncontrolled studies have suggested concomitant inflammatory CNS demyelination similar to multiple sclerosis. The aim of this study was to investigate an involvement of the visual pathway in patients with CIDP. METHODS: In this prospective cross-sectional study, we used high-resolution spectral-domain optical coherence tomography to compare the thickness of the peripapillary retinal nerve fiber layer and the deeper macular retinal layers as well as the total macular volume (TMV) in 22 patients with CIDP and 22 age-matched and sex-matched healthy control (HC) individuals. Retinal layers were semiautomatically segmented by the provided software and were correlated with clinical measures and nerve conduction studies. RESULTS: In patients with CIDP compared with healthy age-matched and sex-matched controls, we found slight but significant volume reductions of the ganglion cell/inner plexiform layer complex (CIDP 1.86 vs HC 1.95 mm3, p = 0.015), the retinal pigment epithelium (CIDP 0.38 vs HC 0.40 mm3, p = 0.02), and the TMV (CIDP 8.48 vs HC 8.75 mm3, p = 0.018). The ganglion cell layer volume and motor nerve conduction velocity were positively associated (B = 0.002, p = 0.02). DISCUSSION: Our data reveal subtle retinal neurodegeneration in patients with CIDP, providing evidence for visual pathway involvement, detectable by OCT. The results need corroboration in independent, larger cohorts.

Naším cílem bylo přispět k objasnění funkčních mozkových změn u pacientů trpících neuroboreliózou a porovnání těchto výsledků s nálezy u pacientů s definitivní roztroušenou sklerózou (RS). Pomocí zrakových evokovaných potenciálů (VEPs) jsme testovali paralelní subsystémy zrakového kortexu (ventrální a dorsální) aktivované anatomicky oddělenými vstupy (parvocelulárním a magnocelulárním), abychom zjistili úroveň jejich postižení při onemocnění neuroboreliózou. U 39 pacientů s definitivní RS a u 100 pacientů s diagnózou neuroborelióza jsme analyzovali VEPs zaznamenané při stimulaci reverzací struktury (R-VEPs) a VEPs vyvolané počátkem pohybu struktury (MVEPs). Z 25 pacientů s RS, u kterých jsme zjistili patologické prodloužení latence hlavního vrcholu R-VEPs (P100), bylo u 14 pacientů nalezeno také prodloužení latence hlavního vrcholu M-VEPs (N160). Naprosto opačnou tendenci jsem zaznamenali u pacientů s neuroboreliózou, kde ze 46 případů s patologickými M-VEPs jsme jen u 14 nalezli současné postižení R-VEPs. Naše studie prokázala funkční poškození zrakové dráhy u části pacientů s neuroboreliózou, které je narozdíl od RS charakterizováno převážným postižením magnocelulárního/dorsálního systému.
