在两名因手术评估的枕叶癫痫患者中，通过颅内电极记录了使用闪烁频闪灯的光驱动情况。同样的技术在术中用于监测视觉皮层。在一名患者中还使用颅内电极获得了视觉诱发电位（VEP）。术前光驱动发生在与产生发作性癫痫样活动的皮层区域不同的位置。视觉诱发电位位于与光驱动相同的部位。在整个切除过程中都对光驱动进行了监测，并且在每次手术结束时都未受影响。两名患者的术后视野测试显示中心视力得以保留，尽管周边视野有所缩小。在枕叶手术期间，使用光刺激对视觉皮层进行术中监测被证明是一种保留中心视力的可靠技术。
Photic driving using a flashing strobe light was recorded via intracranial electrodes in two patients with occipital epilepsy being evaluated for surgery. The same technique was used to monitor the visual cortex intraoperatively. Visual evoked potentials (VEPs) were also obtained using the intracranial electrodes in one patient. Preoperative photic driving occurred in a separate location from the cortical areas producing ictal epileptiform activity. VEPs were located in the same site as photic driving. Photic driving was monitored throughout the resection and remained unaffected at the end of each procedure. Postoperative visual field testing in both patients showed preservation of central vision although some reduction in peripheral fields was seen. Intraoperative monitoring of the visual cortex using photic stimulation proved to be a reliable technique for preserving central vision during occipital lobe surgery.
