Abstract：
The purpose of this case report is to report a case of congenital idiopathic enlargement of extraocular muscles. A four-month-old girl showed limitation of adduction and supraduction in the right eye. A computerized axial tomography (CAT) scan revealed hypertrophy of the lateral rectus muscle and inferior rectus muscle of the right eye. Thyroid hormone and antibody levels were normal. No inflammatory findings on magnetic resonance imaging (MRI). A traction test under general anesthesia revealed a strong limitation of supraduction and a mild limitation of adduction. Therefore, the inferior rectus muscle was recessed 4.5 mm at the age of six months. A partial biopsy of the inferior rectus showed no inflammatory cell infiltration. After the first surgery, the patient\'s limitation of supraduction improved, but the limitation of adduction persisted. So, a 5 mm recession of the right lateral rectus muscle was added at one year and one month. However, the hypertropia of the sound eye became stronger after treatment of amblyopia. Because of the strong limitation of supraduction, tenotomy of the inferior rectus was performed at the age of six years. Postoperatively, no impairment of infraduction occurred, and the limitation of supraduction was mildly improved. Since the findings on MRI were not changed through our observation period, we concluded that the patient had idiopathic external ophthalmoplegia.
摘要：
本病例报告的目的是报告一例先天性特发性眼外肌增大。一个四个月大的女孩在右眼中表现出内收和上吸的局限性。计算机轴向断层扫描（CAT）扫描显示右眼的外侧直肌和下直肌肥大。甲状腺激素和抗体水平正常。磁共振成像（MRI）没有炎症发现。在全身麻醉下进行的牵引试验显示，上吸的局限性很强，内收的局限性很轻微。因此,6月龄时，下直肌凹陷4.5毫米。下直肌部分活检显示无炎性细胞浸润。第一次手术后,患者对超抽吸的局限性得到改善，但是内收的局限性仍然存在。所以,在一年零一个月时，增加了右直肌外侧5毫米的衰退。然而,弱视治疗后，有声眼的高斜视变得更强。由于超吸力的强烈局限性，在6岁时进行了下直肌肌腱切开术。术后,没有发生侵权损害，超抽吸的局限性得到了轻微的改善。由于MRI的发现在我们的观察期间没有改变，我们的结论是患者患有特发性眼外肌麻痹.
