Perioperative visual loss (POVL), a rare but devastating complication, has been reported after spine, cardiac, and head-neck surgeries.The various causes include ischemic optic neuropathy, central or branch retinal artery occlusion, and cortical blindness. The contributory factors described are microvascular diseases and intraoperative hemodynamic compromise. However, the exact association of these factors with post-operative blindness has not yet been confirmed. A case of POVL with caesarian section surgery is being presented. The visual loss occurred due to a combined occlusion of central retinal artery and vein.The causes, presentation, and risk factors of POVL after non-ocular surgery are being discussed.
围手术期视力丧失（POVL）是一种罕见但极具破坏性的并发症，在脊柱、心脏和头颈手术后均有报道。其病因多样，包括缺血性视神经病变、视网膜中央动脉或分支动脉阻塞以及皮质盲。已描述的促成因素有微血管疾病和术中血流动力学不稳定。然而，这些因素与术后失明的确切关联尚未得到证实。本文报告了一例剖宫产手术导致的POVL病例。视力丧失是由于视网膜中央动静脉联合阻塞所致。本文还讨论了非眼科手术后POVL的病因、表现及危险因素。
