Retinal and cortical potentials to reversing checkerboard stimuli (P-ERG, P-VECP) were recorded simultaneously in ten patients with disease of the central retina and eleven patients with tumor-related optic nerve changes. While both groups exhibited comparable P100 delays in the P-VECP, delays of the q component in the P-ERG were only observed in the group with retinal disease. Thus, measurement of P-ERG and P-VECP latencies enables retinal to be distinguished from post-retinal disease in cases with visual disturbances where there are no obvious fundus changes.
在10例视网膜中央疾病患者和11例肿瘤相关视神经病变患者中，同时记录了对翻转棋盘格刺激的视网膜和皮质电位（P-ERG，P-VECP）。虽然两组在P-VECP中均表现出相当的P100延迟，但仅在视网膜疾病组中观察到P-ERG中q成分的延迟。因此，在没有明显眼底改变的视力障碍病例中，测量P-ERG和P-VECP潜伏期能够区分视网膜疾病和视网膜后疾病。
