目的: 报道原发性空泡蝶鞍综合征致双眼视乳头水肿病案 1 例。

方法: 回顾性研究1例原发性空泡蝶鞍综合征致双眼视乳头水肿患者的临床表现、眼底改变、CT 和 MRI 影像学检查的特征、治疗方法及疗效。

结果 : 原发性空泡蝶鞍综合征致双眼视乳头水肿除有典型视乳头水肿的临床表现外，蝶鞍 MRI 亦显示垂体窝呈液型信号、垂体上缘受压凹陷、垂体变薄等典型空泡蝶鞍影像学表现。手术治疗后患者视乳头水肿改善、视力提高。

结论: 蝶鞍 MRI 是诊断原发性空泡蝶鞍综合征的首选影像学检查方法。视力下降明显的患者及时行蝶鞍区手术，术后效果良好。

Purpose:To report a case of papilloedema caused by primary empty sella turcica syndrome.

Methods:Retrospectively review the clinical and physical features, magnetic resonance imaging records and therapies of a patient with papilloedema caused by primary empty sella turcica syndrome.

Results: Except for typical clinical manifestation of papilloedema , a characteristic magnetic resonance imaging (MRI) can be found in a case of papilloedema caused by primary empty sella turcica syndrome. These imaging features are that sella turcica expanded, the inside of sella turcica was filled with cerebrospinal fluid(CSF) signal, pituitary gland was pressed, flatted and near the basis of sella turcica. Papilloedema was relieved and acuity of vision improved after surgery.

Conclusions:MRI is the preferred imaging technique for patient with papilloedema caused by primary empty sella turcica syndrome. If acuity of vision apparentlydecreases,surgery is necessary, and therapeutic effect is excellent.

目的：中重度甲状腺相关眼病内下壁骨性减压联合脂肪减压术的临床疗效观察。方法：回顾性分析25例(31眼)在浙江大学医学院附属第二医院眼科行内下壁骨性减压联合脂肪减压术治疗的甲状腺相关眼病患者，观察时间为2020年1月至2022年1月。术前所有患者均进行了眼眶CT检查，并对双眼视力、眼球突出、复视及双眼外观形态进行了测量。手术效果评价指标为：术后眼球突出度、视力和复视程度，并对相关数据进行统计和分析。结果：术后眼球突出度回退2~6 mm，平均回退(3.45±0.93)mm，切除眶内脂肪1.4~3.6 mL，平均切除(2.33±0.66)mL，外观恢复满意。4例患者术前存在复视，2例患者术后新发复视，术前已存在复视的患者，术后复视程度并未加重，新发的2例复视患者均为轻度复视。术后CT检查显示眼眶减压效果良好。结论：内下壁骨性减压与脂肪减压术联合，可以有效扩大眼眶容积，对眼球进行回纳，减少眼球突出程度，改善容貌外观，且手术切口隐蔽美观，具有较好的临床疗效果。

Objective: To observe the clinical efficacy of medial-inferior wall orbital decompression combined with fat decompression in the treatment of moderate-to-severe thyroid associated ophthalmopathy (TAO). Methods: A retrospective analysis was performed on 25 patients (31 eyes) with moderate-to-severe TAO from January 2020 to January 2022 in Eye Hospital of Zhejiang University, who were treated with medial-inferior wall orbital decompression combined with fat decompression. All of patients were given orbital computed tomography to measure visual acuity, exophthalmos, diplopia and ocular appearance before operation. The preoperative and postoperative exophthalmos, visual acuity and diplopia before and after operation were taken as efficacy evaluating indicators. The related data was counted and analyzed statistically. Results: After operation, the reduction of exophthalmos was 2-6 mm, with an average of (3.45±0.93) mm, the volume of intrazonal fat-removal was 1.4-3.6 mL, with an average of (2.33±0.66) mL, with a satisfactory appearance. There were 4 cases of preoperative diplopia and 2 cases of new diplopia after operation, all of which were mild diplopia. Diplopia did not exacerbate after operation in the patients who had diplopia before operation. Conclusion: Medial-inferior wall orbital decompression combined with fat decompression in the treatment of moderate-to-severe TAO can effectively expand orbital volume, reduce exophthalmos, improve appearance with a concealed beautiful surgical incision, showing its good clinical efficacy.
