作者注意到黄斑、视网膜(或脉络膜视网膜)及视神经的遗传性疾病的视网膜电流图(ERG)、眼电图(EOG)和视诱发电位(VEP)。一、遗传性黄斑变性典型的遗传性黄斑变性——除遗传性黄斑囊样变性卵和黄样变性外,暗视ERG异常,虽然较罕见,但有时仍可见,可偶尔见到ERG各成分的振幅都降低及a波减慢(Orpin等,1974)。 Srebro(1977)发现黄斑变性患者的a波波形均有变化,较突出的为a波明显减慢,绝对期延长。
The authors noted retinal current pattern (ERG), electrooculogram (EOG), and visual evoked potential (VEP) of the macular, retinal (or chorioretinal) and hereditary diseases of the optic nerve. First, hereditary macular degeneration typical hereditary macular degeneration - in addition to hereditary cystoid cystoid degeneration and yellow-like degeneration, ocular ERG abnormalities, although rare, but sometimes still visible, and occasionally see ERG of each component Amplitude decreases and a-wave slows (Orpin et al., 1974). Srebro (1977) found that patients with macular degeneration a wave waveform changes, more prominent for a wave significantly slowed down, the absolute period of extension.
