本文52例多发性硬化(MS)中以眼部症状为首发症状的占59.6%,其单纯视力障碍起病者占46.1%,且以单眼视力障碍起病多见。其它包括复视、眼球震颤、单眼外展麻痹和核间性眼肌麻痹。眼科视力检查和眼底检查可提高视神经受累检查阳性率。17例接受视觉诱发电位(VEP)检查,异常率88.2%,其中6例既往无视神经受累表现。VEP双侧异常80%。异常改变主要为各波潜伏期延长,单纯P_(100)延长、一侧波型不规则不易测量、波幅降低及一侧不出波。
This article 52 cases of multiple sclerosis (MS) in the first symptom of eye symptoms accounted for 59.6%, the incidence of simple vision disorders accounted for 46.1%, and the onset of monocular vision disorders more common. Others include diplopia, nystagmus, monocular abduction and intercostal ophthalmoplegia. Eye examinations and fundus examination can increase the positive rate of optic nerve involvement check. 17 cases underwent visual evoked potential (VEP) examination, the abnormal rate of 88.2%, of which 6 cases of past neurological involvement of the performance. VEP abnormal bilateral 80%. Abnormal changes are mainly prolonged latency of each wave, simple P_ (100) extended, irregular side of the waveform is not easy to measure, reduce the amplitude and no wave on one side.
