BACKGROUND To investigate the surgical outcomes of strabismus related to iatrogenic occlusion of the ophthalmic artery and its branches from cosmetic facial filler injection. METHODS A retrospective study was performed on 6 patients who underwent strabismus surgery among 23 patients who had suffered occlusion of the ophthalmic artery and its branches after cosmetic facial filler injection. Initial, preoperative and final ocular motility examinations, the type of surgery and surgical outcomes were evaluated. RESULTS At initial presentation, visual acuity was no light perception in 5 patients and hand motion in one patient. Five out of 6 patients showed initial ophthalmoplegia. Among these 5 patients, eye motility fully recovered in 3 patients although sensory strabismus developed during follow-up, while the remaining 2 patients had persistent ocular motility limitations. Strabismus surgery was performed at 2.2 ± 1.5 years after iatrogenic ophthalmic artery occlusion. Preoperatively, 5 of the 6 patients showed exotropia, and one patient had esotropia. Vertical deviation was found in 3 out of 6 patients in addition to the horizontal deviation. Successful outcome was achieved only in the 4 patients without persistent ophthalmoplegia after 1.4 ± 1.0 years from surgery. The other two patients with persistent ocular motility limitations failed to achieve successful alignment after surgery, and one patient eventually underwent evisceration due to phthisis bulbi. CONCLUSIONS In our study, surgical outcomes of strabismus caused by cosmetic facial filler injection were successful only in patients without persistent ophthalmoplegia at the time of surgery.

化妆品填充剂注射引起的医源性眼动脉阻塞后斜视的手术效果。

背景技术研究从美容性面部填充剂注射引起的与眼动脉及其分支的医源性闭塞有关的斜视的手术效果。方法对23例眼部动脉及其分支闭塞性注射美容填充剂后发生斜视手术的患者进行回顾性研究。评估了最初，术前和最终的眼球运动检查，手术类型和手术结局。结果在最初的陈述中，有5位患者没有视力，有1位患者没有手部动作。6例患者中有5例出现初次眼肌麻痹。在这5例患者中，有3例患者的眼球运动完全恢复，尽管在随访期间出现了斜视，其余2例患者持续存在眼球运动受限。医源性眼动脉闭塞后的2.2±1.5年进行斜视手术。术前，6例患者中有5例表现出内斜视，而1例患有内斜视。除水平偏差外，在6名患者中有3名发现垂直偏差。手术后1.4±1。0年，仅4例无持续性眼肌麻痹的患者获得了成功的预后。另一位持续眼动受限的患者在手术后未能成功对准，一名患者因鳞茎菲菲症最终接受了内脏摘除术。结论在我们的研究中，
