目的探讨球后麻醉导致青光眼术中一过性视力丧失的临床特征及治疗。方法分析舟山市妇幼保健院2例青光眼患者手术前球后麻醉中出现一过性视力丧失的临床资料,回顾相关文献。结果球后麻醉并发一过性视力丧失较少见,与局麻药物对神经的视觉传导影响及循环障碍引起局部缺血等因素有关。经过处理患者已恢复术前视力。主要治疗措施是:术前含服硝苯地平、尼莫地平等血管扩张剂,选择麻醉方式及局麻药等可减少一过性视力丧失时的发生。结论球后麻醉导致青光眼术中一过性视力丧失应早期发现,积极吸氧扩血管等处理可及时恢复视力。
Objective To investigate the clinical features and treatment of transient loss of vision in glaucoma after posterior capsular anesthesia. Methods The clinical data of two cases of glaucoma patients with postoperative supratentorial anesthesia in Zhoushan MCH hospital were analyzed retrospectively. The results of post-nocturia complicated by transient loss of vision is rare, and local anesthetic drugs on the visual effects of nerve conduction and circulatory disorders caused by ischemia and other factors. After treatment, the patient has been restored preoperative vision. The main treatment measures are: Preoperative buccal nifedipine, nimodipine and other vasodilators, the choice of anesthesia and local anesthetics can reduce the incidence of transient vision loss. Conclusion The postoperative ocular anesthesia lead to glaucoma transient visual loss should be found early, positive oxygen dilation of vasodilators and other treatment can restore vision in time.
