To report a successful surgical management of silicone oil migrated into suprachoroidal space after the repair of the retinal detachment with hemorrhagic choroidal detachment.
Retrospective observational case report. A 30-year-old man with retinal detachment and hemorrhagic choroidal detachment due to severe corneal penetrating injury, underwent a pars plana lensectomy and vitrectomy, endolaser, and silicone oil tamponade followed by transscleral suprachoroidal hemorrhage drainage in the right eye. One week later, a localised temporal choroid elevation was noted. This persistent elevation was confirmed by operation research to be silicone oil migration into suprachoroidal space.
The migrated silicone oil was drained via trans-scleral cut down, and the intravitreal silicone oil was removed and replaced by 16% C2F6. Over the next 2 weeks, the elevation vanished and the choroid became completely flat.
The migration of silicone oil into suprachoroidal space is a rare complication of vitrectomy. The pathway of the migration is most likely through internal orifice of sclerotomy sites. Trans-scleral drainage surgery is an effective method to remove the migrated silicone oil from suprachoroidal space.
报告1例视网膜脱离合并出血性脉络膜脱离修复术后硅油迁移至脉络膜上腔的成功手术治疗病例。
回顾性观察病例报告。一名30岁男性因严重角膜穿通伤导致视网膜脱离和出血性脉络膜脱离，右眼接受了玻璃体切割联合晶状体切除、眼内激光光凝及硅油填充治疗，随后行经巩膜脉络膜上腔出血引流术。一周后，发现颞侧局限性脉络膜隆起。经手术探查证实，这种持续性隆起是硅油迁移至脉络膜上腔所致。
通过经巩膜切开引流排出迁移的硅油，取出眼内硅油并置换为16%的六氟乙烷（C2F6）。在接下来的2周内，隆起消失，脉络膜完全平复。
硅油迁移至脉络膜上腔是玻璃体切除术后一种罕见的并发症。迁移途径很可能是通过巩膜切口的内口。经巩膜引流手术是从脉络膜上腔清除迁移硅油的有效方法。
