OBJECTIVE
To survey the role of pattern electroretinography (PERG) and pattern visual evoked potentials (VEPs) in the process of clinical evaluation of neuro-ophthalmological cases. The study is illustrated with the electrophysiological findings of 231 patients sent to our laboratory in 2005 because of the suspicion of damage in the optic pathway.
METHODS
The RETIport program of the ROLAND equipment (Wiesbaden-Germany) was used to record PERGs and VEPs. The recordings were done according to the recommendations of the International Society for Clinical Electrophysiology of Vision.
RESULTS
The combined application of PERG and VEP provided useful data on the retino-cortical conduction time and hence demyelinisation. The comparison of the N35/P50 and P50/N90 amplitudes of the PERG recordings greatly promoted the diagnostic procedure.
CONCLUSIONS
The combined application of PERG and VEP methods is recommended in the assessment of optic nerve function of neuro-ophthalmological patients.
目的
探讨图形视网膜电图（PERG）和图形视觉诱发电位（VEP）在神经眼科病例临床评估过程中的作用。本研究通过2005年因怀疑视路受损而送至我们实验室的231例患者的电生理检查结果进行说明。
方法
使用ROLAND设备（德国威斯巴登）的RETIport程序记录PERG和VEP。记录按照国际视觉临床电生理学会的建议进行。
结果
PERG和VEP的联合应用提供了有关视网膜-皮质传导时间以及脱髓鞘的有用数据。PERG记录的N35/P50和P50/N90振幅的比较极大地促进了诊断过程。
结论
在评估神经眼科患者的视神经功能时，建议联合应用PERG和VEP方法。
