Three patients suffering from sudden occipital blindness following basilar artery occlusion underwent electroretinography and visual evoked potential (VEP) examinations. The VEPs performed early in those blind patients and repeated later seem to be of prognostic value. Responses of normal shape and amplitude after monocular and binocular stimulation were followed by complete recovery of vision. Unequal and subnormal VEPs obtained following monocular stimulation, and even smaller responses reached after binocular stimulation, accompanied permanent unilateral occipital damage resulting in homonymous hemianopsia. Lack of VEP was proved to be a preceding sign of permanent blindness.
三名基底动脉闭塞后突发枕叶失明的患者接受了视网膜电图和视觉诱发电位（VEP）检查。在这些失明患者早期进行并随后重复进行的VEP检查似乎具有预后价值。单眼和双眼刺激后出现正常形状和振幅的反应，随后视力完全恢复。单眼刺激后获得的VEP不等且低于正常，双眼刺激后甚至出现更小的反应，伴有永久性单侧枕叶损伤，导致同侧偏盲。VEP缺失被证明是永久性失明的先兆。
