Visual potentials induced with a checker pattern were studied in a group of patients with damage to the visual pathways at different levels, and were compared with similar potentials in 10 adult subjects without diseases. A statistically significant prolongation of latency of the main deflections (N1, P max and N2) was observed in the group of 14 patients with optic nerve damage, while in 10 patients with lesions above the chiasma different, often normal responses were obtained. High-grade deformity of visual potentials was observed in 2 cases of visual agnosia. The study of visual evoked potentials may be in the opinion of the authors, useful in cases of damage to the optic nerve, retina and cortical visual centres.
对一组不同水平视觉通路受损的患者进行了棋盘格图案诱发的视觉电位研究，并与10名无疾病的成年受试者的类似电位进行了比较。在14例视神经损伤患者中观察到主要偏转（N1、Pmax和N2）潜伏期有统计学意义的延长，而在10例视交叉以上病变的患者中，获得了不同的、通常正常的反应。在2例视觉失认症患者中观察到视觉电位的高度畸形。作者认为，视觉诱发电位的研究对视神经、视网膜和皮质视觉中枢受损的病例可能有用。
