Duane syndrome is a dysinnervation disorder that frequently involves secondary anomalous eye movement, in particular, ocular retraction and the narrowing of the palpebral fissure on the adduction. Pseudo-Duane syndrome is caused by a mechanical restriction that produces clinical findings similar to those of Duane syndrome. Most patients with pseudo-Duane syndrome have restrictive pathologies on the medial side of the globe, such as entrapment of the medial rectus muscle. We report the case of a 44-year-old man with pseudo-Duane syndrome in whom we identified a lateral orbital wall fracture and entrapment of the soft tissue surrounding the lateral rectus muscle by computed tomography. To the best of our knowledge, this etiology of pseudo-Duane syndrome has not been previously reported.
杜安综合征是一种神经支配异常疾病，常伴有继发性异常眼动，尤其是眼球后缩以及内收时睑裂变窄。假性杜安综合征由机械性限制引起，其临床表现与杜安综合征相似。大多数假性杜安综合征患者存在眼球内侧的限制性病变，如内直肌嵌顿。我们报告了一例44岁患有假性杜安综合征的男性患者，通过计算机断层扫描，我们发现其存在眶外侧壁骨折以及外直肌周围软组织嵌顿。据我们所知，此前尚未有关于假性杜安综合征这一病因的报道。
