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.
