| 摘 要： | 目的：分析图形视觉诱发电位（PVEP）的潜伏期（LP100）及振幅（AP100）对前部缺血性视神经病变（AION）视神经传导异常的诊断价值。方法：对临床证实为AION的48例单眼发病的患者行PVEP检查,对LP100及AP100诊断AION的敏感度及特异度进行对比分析。结果：LP100延长诊断AION视神经传导异常的敏感度及特异度分别为58.3%及95.8%,AP100降低诊断AION视神经传导异常的的敏感度及特异度分别为85.4%及89.6%;如果综合LP100AP100这两项指标,以两项指标中任意一项阳性即诊断AION存在视神经传导异常,可获得97.9%的敏感度及87.5%的特异度。结论：PVEP在诊断AION视神经传导异常中有重要价值,综合潜伏期及振幅这两项指标可以明显提高诊断效率。 |

| Abstract: | Objective:To evaluate the clinical effect on amplitude and latency of pattern-reversal visual evoked potential (PVEP) in patients with anterior ischemic optic neuritis.Methods:Forty-eight ischemic optic neuritis patients were selected.The diagnostic efficiency of amplitude and latency of pattern revereal visual evoked potentiall were evaluated. Results: The sensitivity of LP100 in diagnosing ischemic optic neuritis was 58.3% and the specificity was 95.8% in nerve conduction abnormal. The sensitivity of AP10... |
