Post-operative vision loss (POVL) can be a devastating complication of neurosurgical procedures and is unusual in the pediatric population. Mechanisms of POVL include direct optic nerve injury, vascular occlusion, or indirect malperfusion resultant from surgeries with substantial blood loss or fluid shifts, with prone positioning being a major risk factor for these events. Posterior ischemic optic neuropathy (PION) is a rare cause of POVL and is associated with a poor prognosis for recovery of visual function. We present a case of PION following a supine bifrontal craniotomy for a frontal epidural abscess secondary to pan-sinusitis in a pediatric patient. This is an unusual reported case in that no additional traditional risk factors were identified. We present clinical and radiographic findings, diagnostic considerations, treatment strategies, and a literature review. The patient was managed medically and recovered substantial vision in the affected eye.

术后视力丧失 (POVL) 可能是神经外科手术的破坏性并发症，在儿科人群中并不常见。POVL 的机制包括直接视神经损伤、血管闭塞或由大量失血或液体转移手术引起的间接灌注不良，俯卧位是这些事件的主要危险因素。后部缺血性视神经病变 (PION) 是 POVL 的罕见原因，并且与视觉功能恢复的不良预后相关。我们介绍了一例儿科患者继发于泛鼻窦炎的额叶硬膜外脓肿在仰卧双额开颅手术后发生 PION 的病例。这是一个不寻常的报告案例，因为没有发现额外的传统风险因素。我们介绍临床和影像学发现、诊断考虑、治疗策略、和文献综述。患者接受了医学治疗，受影响的眼睛恢复了大量视力。
