摘  要:目的:探讨白内障手术前视觉电生理检查,评估视功能的价值。方法:回顾性白内障患者手术前闪光视网膜电流图(flashelectrotinogram,F-ERG)暗适应、闪烁反应,闪光视诱发电位F-VEP及多焦视网膜电图m-ERG(Firstorderkernel,FOK一阶反应)检查与正常对照组结果分析,及其与术后视力、眼底情况的关系。结果:白内障手术前闪光视网膜电图F-ERG暗适应、闪烁反应检查呈降低型,多焦视网膜电图m-ERG中心反应密度低平,高度近视、眼底病白内障下降更明显,伴有闪光视诱发电位F-VEP异常者术后视力差。结论:白内障手术前视觉电生理检查有助于视功能的评估,提高预测术后视力的准确性。· AIM: To explore the visual electrophysiological examination before cataract operation and to evaluate the value of view function.· METHODS: The dark accommodation and flash reaction in preoperative flash electrotinogram (F-ERG), F-VEP and m-ERG of Cataract Group and Normal Group are re-trospected and compared, and their relationship with postoperative visual acuity and eyeground was studied.· RESULTS: F-ERG dark accommodation and flash reaction before cataract operation were descending-ERG. Center reaction density was low and flat. Cataract of high myopic eye and eyeground sickness descended apparently, and those accompanied with abnormal F-VEP had bad postoperative visual acuity.· CONCLUSION Visual electrophysiological examination before cataract operation is beneficial for evaluating the value of view function and raising the accuracy of postoperative visual acuity.·
