| 摘 要： | 目的:对比国特GT-2000NV与RETIscan两套视觉电生理检查系统对正常青年人检查的结果。方法:20例正常军校学员用国特和RETIscan两套系统进行图形视觉诱发电位(PVEP)、视网膜电图(ERG)、多焦视网膜电图(mERG)的检测,两套系统的各相应参数调整至相同或相近。结果:两套系统所检测各结果中除Max-ERGa波幅值外,PVEP和常规ERG的其余各值及mERG在两套系统中差异均有显著性意义。PVEPP100峰时、Rod-ERGa波幅值、Rod-ERGb波峰时、Cone-ERGb波峰时在两套系统的测量中,在α=0.05水准上无相关性,而PVEPP100幅值和常规ERG其余结果在两套系统中均表现为正相关,其中Rod-ERGb波幅值、Max-ERGb波幅值、峰时、Cone-ERGb波幅值、Flick-ERGP2波幅值的相关系数分别为0.679,0.832,0.702,0.756,0.766。mERG环形p波功率密度及各象限p波功率密度及峰时在两套系统中均为正相关,环形p波峰时在α=0.05水准上第1,2,3环无相关性,而第4、5环在α=0.05水准上为正相关。其中环形第1,2,3,4,5环功率密度的相关系数分别为0.443,0.627,0.591,0.592,0.739,其峰时的相关系数分别为0.292,0.269,0.302,0.432,0.810。两套系统在mERG测量中,p波功率密度及峰时的变化具有相同的趋势。结论:国特和RETIscan两套系统在视觉电生理的测量中,其各结果的正常值
