摘要
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 analyze the clinical features and treatment options of transient visual loss after retrobulbar anesthesia in glaucoma surgery.Methods The clinical data of 2 cases of transient visual loss after retrobulbar anesthesia in glaucoma surgery in Zhoushan Maternal and Child Health Hospital were analyzed.The related literatures were reviewed.Results Transient visual loss after retrobulbar anesthesia was not a common clinical sign,which was caused by impairment of visual transduction due to local anesthetic drug and ischemic circulatory disturbances.The patients′ visual acuity recovered after treatment.Giving the patients sublingual nifedipine and nimodipine preoperatively and selection of anesthetic techniques and anesthetics would reduce the occurrence of transient visual loss.Conclusion Transient visual loss after retrobulbar anesthesia in glaucoma surgery should be detected as early as possible.Oxygen inhalation and vasodilative treatment may contribute to the patients′ visual recovery.
