Flash visual evoked potentials (F-VEP's) have been recorded in fifteen patients (thirty eyes) with anterior visual pathway compression lesions before, during and after the operation in relation to clinical visual testing. A grading system for the wide variety of abnormal F-VEP's has been established, based on changes in forty patients (eighty eyes). No significant correlation between change in F-VEP and visual acuity or visual field has been demonstrated. Intraoperative F-VEP's have been found to be sensitive to halothane and to surgical manipulation of the optic nerve and/or chiasm during dissection of the tumour. The technique is considered a useful means of identifying the optic pathway during operation and may assist in prevention of optic damage if the transphenoidal approach is used.
我们记录了15例（30只眼）患有前视觉通路压迫性病变的患者在手术前、手术中和手术后的闪光视觉诱发电位（F-VEP），并与临床视觉测试进行了关联。基于40例（80只眼）患者的变化情况，建立了针对各种异常F-VEP的分级系统。F-VEP的变化与视力或视野之间未显示出显著相关性。术中发现F-VEP对氟烷以及在肿瘤切除过程中对视神经和/或视交叉的手术操作敏感。该技术被认为是术中识别视路的一种有用方法，并且如果采用经蝶窦入路，可能有助于预防视神经损伤。
