title: Surgical management of silicone oil migrated into suprachoroidal space after vitrectomy.
abstract: OBJECTIVE
  To report a successful surgical management of silicone oil migrated into suprachoroidal space after the repair of the retinal detachment with hemorrhagic choroidal detachment.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
