目的:探讨弱视成人视网膜电图明视负波(PhNR)的临床应用价值。方法:正常成人30例,弱视成人30例,分别进行蓝色背景下红色刺激光及白色背景下白色刺激光进行明视负波检查,记录各种检查结果并分析。结果:弱视组PhNR蓝-红刺激及白-白刺激下PhNR反应振幅均值均较正常组降低,而潜伏期和正常组相似,正常组PhNR白-白刺激反应振幅均值较蓝-红刺激光降低,而潜伏期和正常组相似。结论:弱视患者视网膜PhNR蓝-红刺激及白-白刺激反应振幅具有差异。

AIM:To analyze the clinical application value of photopic negative response(PhNR)in amblyopia by comparing the normal adult and amblyopia adult of PhNR.METHODS:PhNR was recorded and analyzed from 30 normal adult eyes and 30 amblyopia adult eyes,using red flashes on a blue background and white flashes on a white background respectively.RESULTS:Amplitudes of PhNR in amblyopia were lower than those of the normal group by red flashes on a blue background and white flashes on a white background,there were statistically significant differences between them.Latencies of PhNR in amblyopia were similar to normal group,there were no statistically significant differences between them.Amplitudes of PhNR by using white flashes on a white background were lower than those by using red flashes on a blue background with statistically significant differences,latencies of PhNR by white flashes on a white background were similar to those by red flashes on a blue background,there were no statistically significant differences.CONCLUSION:The function of retinal ganglion cells of amblyopia is damaged.PhNR by red flashes on a blue background is more sensitive than PhNR by white flashes on a white background.
