An ERG examination according to the international standard was made in 55 patients with pits in the optic nerve disc. 19 of them suffered from concurrent maculopathy. Electroretinography revealed in scotopic responses a significant reduction of amplitudes of oscillatory potentials and reduction of potentials of the b wave in standard (maximal) reactions. Even more markedly the cone reactions and flicker were reduced--responses to intermittent (30 Hz) photostimulation. The authors consider maculopathies with pits a separate nosological unit with possible hereditary transmission. ERG signalizes a more extensive alteration of retinal structures than affection of the centre, probably on the basis of the circulation. Maculopathies with pits are also characterized by the fact that the dramatic drop of amplitudes is associated with the patient's age or the duration of the disease.
对55例视神经盘有凹陷的患者进行了符合国际标准的视网膜电图（ERG）检查。其中19例同时患有黄斑病变。视网膜电图显示，在暗视反应中，振荡电位的振幅显著降低，标准（最大）反应中b波电位降低。更为明显的是，视锥细胞反应和闪光反应降低——对间歇性（30赫兹）光刺激的反应。作者认为伴有凹陷的黄斑病变是一个可能具有遗传传递性的独立病种单元。ERG表明视网膜结构的改变比中心部位的病变更为广泛，这可能是基于血液循环。伴有凹陷的黄斑病变的另一个特点是，振幅的急剧下降与患者的年龄或病程有关。
