PURPOSE
To measure and analyze the electroretinogram (ERG) in patients with retinal vascular occlusion.
METHOD
Fifty-eight cases (59 eyes) of retinal vascular occlusion and the fellow eyes of 47 cases were tested with Ganzfeld ERG. The scotopic and photopic ERG, and oscillatory potentials were tested according to the ERG standard of ISCEV.
RESULTS
The abnormal rates of OPs and b wave were higher in retinal vascular occlusion. The abnormal ERG appeared mostly in CRVO among four types of retinal vascular occlusion. The comparisons of some amplitudes and latencies between the fellow eyes and the affected eyes showed statistically significant difference.
CONCLUSION
The oscillatory potentials and b waves have important roles in evaluating the retinal function of patients with retinal vascular occlusions. There are some clinical significance for comparing ERG between the affected eye and the fellow eye.
目的
测量并分析视网膜血管阻塞患者的视网膜电图（ERG）。
方法
对58例（59只眼）视网膜血管阻塞患者及其中47例患者的健侧眼进行全视野视网膜电图检查。按照国际临床视觉电生理学会（ISCEV）的视网膜电图标准检测暗视和明视视网膜电图以及振荡电位。
结果
视网膜血管阻塞患者中振荡电位和b波的异常率较高。在四种类型的视网膜血管阻塞中，异常视网膜电图大多出现在视网膜中央静脉阻塞（CRVO）中。健侧眼与患侧眼之间的一些振幅和潜伏期比较显示出统计学上的显著差异。
结论
振荡电位和b波在评估视网膜血管阻塞患者的视网膜功能中具有重要作用。比较患眼与健侧眼的视网膜电图具有一定的临床意义。
