Multifocal visual evoked potentials in chronic inflammatory demyelinating polyneuropathy.

摘要: Objective Studies using conventional full-field visual evoked potentials (ffVEP) have reported subtle abnormalities in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). We hypothesize that these can be detected the majority of CIDP enhanced methods. Methods performed a cross-sectional noninterventional study comparing 18 and matched healthy controls multifocal VEP (mfVEP) as technique sensitivity to detect conduction across spectrum optic nerve fibers. Patients confounding diseases (ophthalmologic, diabetes mellitus) were excluded. Results The mean amplitude latency, well low-contrast acuity, did not differ between controls. Subanalyses revealed latency differences concerning superior sector field. Severity markers (ODSS, motor velocity) associated mfVEP delay. Interpretation could adduce evidence for clinically or diagnostically relevant pathway involvement CIDP. identified very restricted field which cannot readily explained biologically, anatomically, pathologically. In summary, we conclude our no parameters
