摘　　要：目的:评价闪光视觉诱发电位(FVEP)、闪光视网膜电图(FERG)或图形视网膜电图(PERG)、眼底照相、眼部B超和光学相干断层扫描(OCT)应用于白内障术前对视功能的评估及对视网膜疾病检出的有效性观察。方法:对148例196眼白内障患者术前应用眼科电生理仪、眼底照相、眼部B超和OCT,根据FVEP和FERG(或PERG)、眼底照相、OCT、眼部B超检查结果的阳性率进行分析。结果:患者148例196眼中,B超检查显示玻璃体混浊165眼(84.2%),无法获取B超图像31眼(15.8%);成功获取眼底照相图像161眼(80.6%),无法获取图像35眼(19.4%);获得有价值VEP、ERG 58眼(29.6%),VEP、ERG未见明显异常138眼(70.4%);成功获取OCT图像167眼(85.2%),无法获取OCT图像29眼(14.8%)。结论:视觉电生理检查、眼底照相、眼部B超和光学相干断层图像结果可对白内障患者术前的视功能状况进行综合评估,多种检查方法相互配合,可进一步提高白内障手术前对视网膜疾病以及其他眼科疾病的检出率。To evaluate the effectiveness of applying visual electrophysiological examination, including flash visual evoked potentials （ FVEP ） , flash electroretinogram （ FERG ） , pattrn electroretinogram （ PERG ） , fundus photography, eye B-type ultrasound, optical coherence tomography （ OCT ） , on visual function assessment and retinal disease detection before cataract surgery. METHODS： Visual elctrophysiological examination, fundus photography, eye B-type ultrasound and OCT were applied in 148 cases （ 196 eyes ） . The positive rate was analyzed according to the results of FVEP, FERG （ or PERG ） , fundus photography, eye B - type ultrasound and OCT.RESULTS： ln 148 cases （ 196 eyes ） , vitreous opacities was showed in 165 eyes （ 84. 2%） by eye B - type ultrasound examination, 31 eyes （15. 8%） without access to B-type ultrasound image; success for fundus camera images in 161 eyes （80. 6%）, and unable to get image in 35 eyes （19. 4%）; the VEP and ERG in 58 eyes （29. 6%） were get valuable, and the VEP and ERG were saw no obvious abnormal in 138 eyes （ 70. 4%）; success for OCT image in 167 eyes （85. 2%）, without access to OCT image in 29 eyes （14. 8%）. CONCLUSlON： Visual elctrophysiological detection, fundus photography, eye B-type ultrasound and OCT can predict the preoperative visual acuity of cataractous patients. A variety of inspection methods complement each other, can further improve detection rate of retinal diseases and other eye disease before cataract surgery.
