The function of the neural retina and the pigment epithelium in 10 patients with gyrate atrophy was examined by the conventional alternating current electroretinogram and by direct current electroretinography to study the c-wave. The a- and b-wave responses were subnormal in all patients and the ERG was undetectable in patients with an advanced stage of the disease. The c-wave was recordable by the DC ERG from three patients with a less advanced stage of the disease. In one patient the c-wave could be recorded only from the other eye but the a- and b-wave responses were recordable in both his eyes.
通过传统的交流电视网膜电图和直流视网膜电图来检测10例回转性萎缩患者的神经视网膜和色素上皮的功能，以研究c波。所有患者的a波和b波反应均低于正常水平，疾病晚期患者的视网膜电图无法检测到。对于疾病程度较轻的3例患者，直流视网膜电图可记录到c波。在1例患者中，仅对侧眼可记录到c波，但其双眼均能记录到a波和b波反应。
