The pigment epithelium-receptor complex, which is supplied from the choroidal circulation, is the main source of the c-wave of the ERG. Occlusion of the central retinal artery (OCRA), which causes serious damage to the inner retinal layers, should therefore not primarily be expected to affect the c-wave amplitude. Nevertheless, conflicting reports of increased, decreased and unchanged c-waves have appeared in the literature. In the present study on four patients with OCRA the affected eyes showed diminished b- and c-waves. On the other hand, both the a-wave and the trough between the b- and c-waves were accentuated in the diseased eyes. Experiments in progress on Cynomolgus monkeys with experimentally induced unilateral OCRA show similar results.
由脉络膜循环供血的色素上皮-感受器复合体是视网膜电图c波的主要来源。因此，预期视网膜中央动脉阻塞（OCRA）主要不会影响c波振幅，因为它会严重损害视网膜内层。然而，文献中出现了关于c波增加、减少和不变的相互矛盾的报道。在本研究中，对4例OCRA患者进行检查，患眼的b波和c波均减弱。另一方面，患眼的a波以及b波和c波之间的波谷均增强。对实验性诱导单侧OCRA的食蟹猴进行的正在进行的实验显示了类似的结果。
