目的 对RP患者F-ERG进行检查,以分析病程和作为眼肌深层巩膜移植术术後疗效跟踪的客观对照指标。方法 采用常规无创伤视觉电生理描记术,测定暗视F-ERG。结果 受检的210名RP患者的420只眼中,F-ERG为“熄灭型”的为67.9％,能记录到ERP的占19.8％,a-波为28.3％,c-波仅为4.0％,能记录到b-波与负後电位的分别为10.7％和7.4％。说明RP患者视网膜对闪光刺激反应的机能已经显著受损。结论 RP患者的F-ERG有不同程度的特有改变,在眼肌深层巩膜移植术进行治疗後,再复查F-ERG时,则观察到某些波重现,或原有波的波幅增加和峰潜伏期缩短。
Objective To examine the F-ERG in patients with RP to analyze the course of the disease and to provide an objective control index for the follow-up of the effect of deep scleral transplantation. Methods Conventional noninvasive visual electrophysiography was used to detect F-ERG. Results In the 420 eyes of 210 RP patients examined, 67.9% of F-ERG was “extinguished”, 19.8% of ERP was recorded, 28.3% of a-wave and 4.0% of c-wave, Can be recorded to the b-wave and negative potential were 10.7% and 7.4%. RP patients with retinal flash response to the function of the flash has been significantly damaged. Conclusions F-ERG in patients with RP have some degree of specific changes. After deep scleral transplantation in ocular muscle, when F-ERG is re-examined, some of the waves are observed or the amplitude of the original wave is increased and the peak Shorten the incubation period.
