目的:观察眼挫伤后进行眼底荧光血管造影(fundus fluorescein angiography,FFA)联合视觉诱发电位(visual evoked potential,VEP)和视网膜电图(electroretinigram,ERG)的特点和临床意义。方法:对32例42眼眼挫伤患者进行FFA,ERG和VEP检查。结果:FFA检查,视网膜震荡伤16眼(38.0%),视网膜挫伤9眼(21.4%),视神经损伤22眼(52.3%)黄斑裂孔2眼(4.7%),脉络膜破裂7眼(9.7%)。视觉电生理检查:32眼(76.1%)挫伤引起闪光ERG的a,b波波幅下降,视力<0.1者26眼(61.9%)闪光VEP的P波潜伏期延迟,波幅下降趋势明显。结论:FFA联合视觉电生理检查对眼挫伤引起的视网膜视神经改变能进行客观、可靠的评价。

AIM:To observe the characteristics and clinical significance of fundus fluorescein angiography (FFA) with visual evoked potential (VEP) and electroretinogram (ERG) after ocular contusion.·METHODS:Forty-two eyes were examined with the FFA,VEP and ERG methods.·RESULTS:In FFA examination,retinal concussion was found in 16 eyes(38.0%),retinal contusion in 9 eyes(21.4%),optic nerve injury in 22 eyes(52.3%),macular hole in 2 eyes (4.7%),choroidal rupture in 7 eyes (9.7%).In Visual electrophysiological examination,32 eyes (76.1%) had contusion-caused a,b-wave amplitude decrease in flash ERG examination,the P wave latency delayed and amplitude decreased evidently in flash VEP examination of 26 eyes (61.9%) of the vision below 0.1.·CONCLUSION:FFA combined with electrophysiological analysis of visual eye can evaluate the optic nerve and whole retinal function reliably and objectively.
