Supernumerary extraocular muscles can cause restrictive strabismus, unusual ocular movements, and a persistent positive forced duction test. Even among patients with clinically typical strabismus, intraoperative testing and surgical exploration may reveal the presence of supernumerary extraocular muscles. We report the case of a patient with exotropic Duane syndrome found intraoperatively to have an accessory lateral rectus muscle, with histopathologically confirmed striated fibers.
额外的眼外肌可导致限制性斜视、异常眼球运动以及持续的阳性被动牵拉试验结果。即使在临床典型斜视患者中，术中检查和手术探查也可能发现存在额外的眼外肌。我们报告一例患有外斜视型杜安综合征的患者，术中发现其有一条副外侧直肌，经组织病理学证实存在横纹肌纤维。
