Ocular neuromyotonia is a rare ocular motility disorder characterized by involuntary contraction of extraocular muscles resulting in paroxysmal diplopia. Although ocular neuromyotonia is reported as a rare complication after radiation therapy, there are a few cases of ocular neuromyotonia in the absence of irradiation. In the reported cases the possibility of vascular compression has been suggested on radiological imaging. The authors report a case of ocular neuromyotonia treated by microvascular decompression of the third cranial nerve, supporting the hypothesis that neurovascular compression may play a role in its pathogenesis. The usefulness of preoperative 3D imaging for microvascular decompression is also discussed.
眼肌肌强直性痉挛是一种罕见的眼球运动障碍，其特征是眼外肌不自主收缩，导致阵发性复视。虽然眼肌肌强直性痉挛被报道为放疗后的罕见并发症，但也有少数在没有照射的情况下发生眼肌肌强直性痉挛的病例。在报告的病例中，影像学检查提示存在血管压迫的可能性。作者报告了一例经第三颅神经微血管减压治疗的眼肌肌强直性痉挛病例，支持神经血管压迫可能在其发病机制中起作用的假说。还讨论了术前 3D 成像对微血管减压的有用性。
