Abstract：
UNASSIGNED: The indication for surgical optic canal decompression (OCD) for traumatic optic neuropathy (TON) remains controversial because there is no reliable predictor of a good outcome. We report the case of a blind patient with TON whose remaining visual-evoked potential (VEP) suggested recovery potential of the injured optic nerve after OCD.
UNASSIGNED: A 48-year-old man had fallen from a height of 7 m, striking his head. He immediately complained of right-eye blindness. He had no light perception and the direct light reflex disappeared from the right pupil, although there was no fracture or traumatic lesion on computed tomography and magnetic resonance imaging. Because the amplitude of the VEP with the right eye stimulation remained unchanged, we performed the right OCD. During surgical OCD, the amplitude and latency of VEP began to improve. Finally, the visual field improved in almost all directions, and eyesight improved to 0.2.
UNASSIGNED: The retained VEP activity in TON may suggest the recovery potential of the injured optic nerve, even in cases of blindness. It is possible that VEP is an indicator of aggressive treatment for TON such as OCD.

摘要：
■外伤性视神经病变（TON）的手术视神经管减压（OCD）的适应症仍然存在争议，因为没有可靠的预后预测指标。我们报告了一名患有TON的失明患者，其剩余的视觉诱发电位（VEP）表明OCD后受损视神经的恢复潜力。
■一名48岁男子从7米高空坠落,敲打他的头。他立即抱怨右眼失明。他没有光线感知，直接的光反射从右瞳孔消失了，尽管计算机断层扫描和磁共振成像没有骨折或创伤性病变。因为右眼刺激的VEP的幅度保持不变，我们做了正确的强迫症。在手术强迫症期间，VEP的振幅和潜伏期开始改善。最后,视野几乎在所有方向都得到了改善，视力提高到0.2。
■TON中保留的VEP活性可能表明受损视神经的恢复潜力，即使在失明的情况下。VEP可能是TON如OCD的积极治疗的指标。
