摘要硅油是眼穿通伤术后玻璃体腔常用的填充物，硅油填充数月后需手术取出，硅油从玻璃体腔异位至眼睑眼眶是非常罕见的并发症，本文报道眼球壁异物取出术后硅油异位于眼睑眼眶的病例。患者因“左眼外伤后肿胀伴睁眼困难3年余”就诊，眼眶CT提示：左侧玻璃体、球后、眼睑下多发边界清楚的高密度影，考虑主要诊断为：左眼眶眼睑肿物，性质待查；左眼上睑下垂。予以左眼眶眼睑肿物摘除术，病理检查结果提示薄壁纤维囊壁组织，伴小血管，内容物清亮。随访1周，左眼上睑稍凹陷，上睑下垂改善。

abstractsSilicone oil insertion is a common modality in vitreoretinal surgeries after ocular perforating injury. It needs surgical removal after several months. Extraocular silicone oil migration to orbit and eyelid is uncommon complication. We reports a case of silicone oil migration to orbit and eyelid. A 41-year-old male presented with left upper eyelid swelling following silicone oil injection 3 years before admission. Orbital computed tomography scan showed multiple high-density well-defined masses in vitreous, left upper eyelid and orbit. We diagnosed the patient with orbital and eyelid mass, meanwhile, speculated mechanical ptosis. Excision of orbital and eyelid masses were performed. Cystic spaces with delicate fibrous wall and small vessels, and clear fluid in cyst were discovered on histologic examination. The patient was followed up after 1 week. The left upper eyelid slightly depressed and the mechanical ptosis was significantly improved.
