目的:评价闪光视觉诱发电位(flash visual evoked potentials,FVEP)和闪光视网膜电图(flash electroretinogram,FERG)或图形视网膜电图(pattern electroretinogram,PERG)对白内障患者术后视力预测的可靠性。方法:对412例白内障患者术前应用GT-2000NV型眼电生理自动测试仪,根据FVEP和FERG(或PERG)结果对白内障术后最佳矫正视力(best-corrected visual acuity,BCVA)进行相关性分析。结果:术前FERGb波和FVEP振幅的综合值与术后BCVA呈显著正线性相关性(r=0.492,0.487;P<0.05)。结论:视觉电生理检查结果可综合评估白内障患者术后的视功能状况。

AIM:To study visual electrophysiological examination,including flash visual evoked potentials(FVEP),flash electroretinogram(FERG),pattern electroretinogram(PERG),to predict the postoperative visual acuity of cataractous patients.METHODS:Visual electrophysiological examination was used to evaluate the visual function after phacoemulsification and intraocular lens implantation in 412 cases 412 eyes.Postoperative best-corrected visual acuity(BCVA) was analyzed the relationship according to FVEP,FERG(or PERG).RESULTS:More obvious linear relationship was shown between the BCVA and the combination of b wave’s amplitude of FERG with wave’s amplitude of FVEP(r=0.492,0.487;P<0.05).CONCLUSION:Visual electrophysiological detection can predict the postoperative visual acuity of cataractous patients.
