应用视觉电生理检测设备，采用半视野ＰＶＥＰ瞬态图形翻转方法进行检测。选择正常体验志愿者３０人和经临床疑诊为垂体肿瘤后经ＣＴ确诊的病人２０例，分别进行半视野ＰＶＥＰ检查，进行统计学分析，两组的半野ＰＶＥＰ检测在统计学上有显著差异。从而证实了垂体瘤病人的半视野ＰＶＥＰ的Ｐ１００波潜伏期、振幅均出现明显差异，因此半视野ＰＶＥＰ检测可以做为早期垂体瘤病人的临床量化指标。
Application of visual electrophysiology testing equipment, using half-field PVEP transient pattern flip method for detection. Thirty patients with normal experience and 20 patients with CT confirmed by clinical suspicion of pituitary tumor were selected, and the semi-field PVEP was performed respectively for statistical analysis. There was a statistically significant difference between the two groups in PVEP detection. Thus confirms the half-field pituitary tumor PVEP P100 wave latency and amplitude were significantly different, so the semi-field PVEP detection can be used as a clinical quantitative early pituitary tumor patients.
