摘要 目的 探讨球周及球后麻醉致暂时性失明的原因及其防治方法。方法 通过回顾性分析9例(9只眼)球周或球后麻醉致暂时性失明病例的临床表现、VEP及FFA检查所见、治疗方法及预后情况,探讨其发生原因及有效防治途径。结果 本组病例于注射麻药后5~80min发现无光感,VEP显示潜伏期及振幅均有不同程度延长及降低,5例患者FFA显示视网膜动脉痉挛变细,其中2例伴视网膜水肿,经及时处理后均获得了较理想视力恢复,复查VEP均恢复至术前状态,FFA未见异常。结论 球周或球后麻醉致暂时性失明可能与其引起视网膜血循环障碍、阻断视觉传导及对视神经机械性损伤等途径有关,积极预防、及时发现和治疗具有重要的临床意义。 Objective To study the causes and the prevention and treatment ways of the blackout caused by retrobulbar and peribulbar anesthesia. Methods The clinical manifestation,the show of VEP and FFA,the treatment ways and the prognosis of the 9 patients(9 eyes) of blackout caused by retrobulbar and peribulbar anesthesia were analysed retrospectively. Results The 9 patients were found amaurosis 5-80 minutes after anesthesia. The latent periods were lengthened and oscillation ranges were lowered of the VEPs of the 9 patients. The FFAs of 5 patients showed the retina arteries angiospasm and 2 of them combined with retinal edema. The visual acuities of all patients recovered well after timely treatment. The VEPs rechecked showed the same as preoperation arid the FFAs rechecked of the 5 patients showed normal. Conclusion The temporary blindness caused by retrobulbar and peribulbar anesthesia were related possibly with the retina blood circulation obstacle,the visual nerve physical hurt and the vision conduction block caused by them. The actively prevention,timely discovery and treatment have important clinic meaning.
