目的：探讨图形视觉诱发电位(P - VEP)在不同时间频率对原发性青光眼诊断的敏感性。
AIM: To investigate the sensibility of pattern visual evoked potential (P-VEP) on the diagnosis of glaucoma in different temporal frequency.
本文对80例弱视儿童和30例同年龄正常儿童同期进行图形视觉诱发电位(P -vep)的检测。
The pattern visual evoked potential (P-VEP) of 80 children with amblyopia and 30 normal children at the same age was detected.
传统的方法是采用闪光视觉诱发电位和图形视觉诱发电位来进行术中的视功能监护，但是这些检测方法的副作用较大，易造成眼球损伤，对病人造成伤害。
The traditional measurement usually USES flash VEP and pattern VEP to monitor the vision channel. But these methods have strong side effect, they can damage eyeball and damage the patients.
