对正常人及视神经萎缩患者进行瞬态发光二级管ＶＥＰ（ＴＩＥＤ－ＶＥＰ）和稳定发光二极管ＶＥＰ（ＳＬＥＤ－ＶＥＰ）联合检测，分析两种刺激状态下各检测指标的灵敏性和所能反应的视觉信息。结果：异常阳性率ＴＬＥＤ－ＶＥＰ为３３．３３％，ＳＬＥＤ－ＶＥＰ检测指标光驱动临界频率（ｃｒｉｔｉｃａｌｆｒｅｑｕｅｎｃｙｏｆｐｈｏｔｉｃｄｒｉｖｉｎｇ，ＣＦＰＤ）为８８．２４％，两者联合检测异常阳性率达９６．０８％。视力与ＣＦＰＤ及ＴＬＥＤ－ＶＥＰ的Ｐ（１００）振幅值正相关，与Ｎ（７０）、Ｐ（１００）潜时无关。对ＣＦＰＤＥ及ＴＬＥＤ－ＶＥＰ检测指标所反应的生理基础和视功能信息进行了探讨。
To detect the sensitivity and responsiveness of each test index under both stimulus conditions, the transient light-emitting diode VEP (TIED-VEP) and the stabilized light-emitting diode VEP (SLED-VEP) Visual information. Results: The positive rate of TLED-VEP was 33.33%. The critical frequency of photodynamic therapy (SLP-VEP) was 88.24%. The positive rate of SLED-VEP was 96.08%. The visual acuity positively correlated with the amplitude of P (100) of CFPD and TLED-VEP, but not with the N (70) and P (100) latency. The physiological basis and visual function information of CFPDE and TLED-VEP detection indexes were discussed.
