Pattern evoked responses have been recorded in 19 patients with compression of the optic nerve, chiasm or tract, verified at operation. These included 4 patients with orbital tumours, 5 with intracranial meningiomas, 2 with craniopharyngiomas and 8 with pituitary tumours. The evoked response was abnormal in all except one of these patients. The pattern of abnormalities in the response, however, differed from that in the earlier series of patients with primary demyelinating disease. The incidence of delayed responses was much lower, and the magnitude of the delays was smaller. Absent responses were particularly characteristic of patients with intracranial meningiomas. Tumours arising in the region of the sella turcica were associated with a high incidence of abnormalities of the waveform of the response, and asymmetry of the field of the occipital evoked potential was especially characteristic of this group. Most, but not all, asymmetric cases were associated with field defects.
在19例经手术证实存在视神经、视交叉或视束受压的患者中记录到了图形诱发反应。其中包括4例眼眶肿瘤患者、5例颅内脑膜瘤患者、2例颅咽管瘤患者和8例垂体肿瘤患者。除1例患者外，其余患者的诱发反应均异常。然而，反应中的异常模式与早期原发性脱髓鞘疾病患者系列中的模式不同。延迟反应的发生率低得多，延迟的程度也较小。无反应是颅内脑膜瘤患者的特别特征。蝶鞍区发生的肿瘤与反应波形异常的高发生率相关，枕叶诱发电位视野不对称是该组的特别特征。大多数（但不是全部）不对称病例与视野缺损有关。
