A retrobulbar block is a regional anesthetic nerve block in the retrobulbar space. Optic neuropathy following retrobulbar injection is a well-recognized and rare complication of the procedure with an unknown incidence. This article reviews the relevant literature regarding vision loss following this procedure. Mechanisms of injury to the optic nerve as well as methods that can be employed to minimize the risk of optic neuropathy will be explored, including alternatives to retrobulbar anesthesia.
球后阻滞是一种在球后间隙进行的区域麻醉神经阻滞。球后注射后发生的视神经病变是该操作一种公认的罕见并发症，其发生率尚不清楚。本文回顾了有关该操作后视力丧失的相关文献。将探讨视神经损伤的机制以及可用于降低视神经病变风险的方法，包括球后麻醉的替代方法。
