The color stimulated electroretinogram (ERG) was found abnormal in 104 eyes of 64 cases of age-related macular degeneration (AMD). The number of a-wave troughs with dark adapted red stimulation decreased in 69 eyes, of which 27 eyes also showed diminished a- and b-waves under dark and light adaptation. Among the remaining 35 eyes that demonstrated no decrease in the number of a-wave troughs, there were 6 eyes with a- and b-wave diminution under dark and light adaptation. The findings indicated that the ERG anomalies in AMD were detected more readily with dark adapted red stimulation, particularly evident in the wet type of AMD, thus conducive to the judgement of visual impairment and prognosis.
在64例年龄相关性黄斑变性（AMD）患者的104只眼中，发现彩色刺激视网膜电图（ERG）异常。69只眼在暗适应红色刺激下a波谷的数量减少，其中27只眼在暗适应和明适应下a波和b波也减弱。在其余35只a波谷数量未减少的眼中，有6只眼在暗适应和明适应下a波和b波减弱。这些结果表明，在AMD中，暗适应红色刺激更容易检测到ERG异常，在湿性AMD中尤为明显，从而有助于判断视力损害和预后。
