目的观察视网膜分支静脉阻塞多焦视网膜电图特征,分析其与视野改变的相关性.方法回顾性临床病例自身对照研究.对2006～2009年在承德医学院附属医院眼科就诊的32例(32只眼)视网膜颞上支分支静脉阻塞患者进行多焦视网膜电图检查,分析其一阶反应,N1、P1波振幅密度值及潜伏期;并行视野平均光敏感度检查.结果视网膜静脉阻塞区域多焦视网膜电图N1、P1波振幅密度下降,潜伏期延长;P1波振幅密度与视野平均光敏感度差异行统计学意义(r=0.545,P<0.01 ).结论视网膜分支静脉阻塞多焦视网膜电图能够准确反映发生在视网膜局部病变的位置与程度,并与视野改变具有相关性.

Objective To observe the characteristics of multifocal electroretinogram in branch retinal vein occlusion and analyze its correlativity with perimetry.Methods Implemented multifocal electroretinogram to 32 cases (32 eyes) of temporal branch retinal vein occlusion and analyzed the first-order kernel responses: amplitude density and latency of N1-wave, P1-wave; Implemented perimetric sensitivity test and analyzed mean light sensitivity.Results Compared with collateral eyes,N1-wave, P1-wave amplitude densities of thrombotic retina attenuated, latencies were delayed.Statistically positive correlation was founded between mean light sensitivity and P1-wave amplitude density (r=0.545, P <0.01).Conclusions Responses from multifocal electroretinogram accurately demonstrate the location and degree of retinal dysfunction in branch retinal vein occlusion and correlate well with perimetry.
