Although inferior alveolar nerve block is one of the most common procedures performed at dental clinics, complications or adverse effects can still occur. On rare occasions, ocular disturbances, such as diplopia, blurred vision, amaurosis, mydriasis, abnormal pupillary light reflex, retrobulbar pain, miosis, and enophthalmos, have also been reported after maxillary and mandibular anesthesia. Generally, these symptoms are temporary but they can be rather distressing to both patients and dental practitioners. Herein, we describe a case of diplopia caused by routine inferior alveolar nerve anesthesia, its related physiology, and management.
尽管下牙槽神经阻滞是牙科诊所最常进行的操作之一,但仍可能发生并发症或不良反应。在极少数情况下,上颌和下颌麻醉后也有报道出现眼部障碍,如复视、视力模糊、黑矇、瞳孔散大、异常瞳孔光反射、球后疼痛、瞳孔缩小和眼球内陷。一般来说,这些症状是暂时的,但对患者和牙科医生来说都相当困扰。在此,我们描述一例由常规下牙槽神经麻醉引起的复视病例、其相关生理学机制及处理方法。
