视觉电生理检查对白内障患者术后视力的评估

Visual electrophysiological examination in prediction the postoperative visual acuity of cataract

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.
