视神经脊髓炎的视觉诱发电位临床分析
Clinical analysis of visual evoked potential in neuromyelitis optica
摘要
Abstract
Objective To investigate the significance of visual evoked potential (VEP) in patients with neuromyelitis optica (NMO) or relapse-longitudinally extensive transverse myelitis (r-LETM).Methods The VEP were examined iu 16 inpatients with NMO and 15 inpatients with r-LETM,and the results were compared with those from normal control group.Results The latency of P100 in NMO group was significantly longer than that in control group,and the amplitude was decreased significantly in NMO group (all P ＜ 0.05);the abnormal rate of latency was higher than that of amplitude.The P100 amplitude was significantly lower in r-LETM group than that in control group (P ＜ 0.05),while no significant difference was found in P100 latency between the two groups (P ＞ 0.05);the abnormal rate of amplitude was higher than that of latency.The latency was significantly longer in NMO group than that in r-LETM group (P ＜ 0.05),but no significant difference was found in amplitude between the two groups (P ＞ 0.05).Conclusions The VEP in NMO was characterized as prolonged latency with or without reduction of amplitude,and wave could disappeared in a badly condition.VEP could help to detect sub-clinical optic nerve damage of r-LETM,which might be helpful in the early diagnosis of NMO.关键词
