目的对31例多发性硬化临床与视觉诱发电位进行分析,探讨视觉诱发电位在多发性硬化诊断中的价值。方法总结31例多发性硬化的临床特点,结合文献,对患者视觉诱发电位,并对比MRI检查展开探讨。结果视觉诱发电位,在早期发现视神经病变及特异性方面均高于MRI,是客观鉴别病灶存在,发现亚临床病灶的重要方法。结论多发性硬化具有空间、时间的多发性,诊断主要依靠临床及辅助检查,视觉诱发电位对多发性硬化具有较高的敏感性和特异性,客观鉴定病灶的存在,是提高多发性硬化诊断率的重要检查方法之一。
Objective To analyze the clinical and visual evoked potentials of 31 patients with multiple sclerosis and explore the value of visual evoked potentials in the diagnosis of multiple sclerosis. Methods The clinical features of 31 patients with multiple sclerosis were summarized. The visual evoked potentials were compared with those of the literature and compared with MRI examination. Results Visual evoked potential, in the early detection of optic neuropathy and specificity are higher than MRI, is to objectively identify the presence of lesions, found that subclinical lesions an important method. Conclusions Multiple sclerosis has multiple spatial and temporal manifestations. The diagnosis mainly relies on clinical and auxiliary examinations. Visual evoked potentials are highly sensitive and specific to multiple sclerosis. Objectively identifying the presence of lesions and improving the diagnostic rate of multiple sclerosis One of the important inspection methods.
