Purpose:To report a successful surgical management of silicone oil migrated into the suprachoroidal space.

Method:A 30-year-old man with a 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 the suprachoroidal space.
Results:The migrated silicone oil was drained via trans-scleral cutdown，and the intravitreal silicone oil was removed and replaced by 16%C2F6.Over the next 2weeks，the elevation vanished and the choroid became completely flat.

Conclusion:ilicone oil migration into the suprachoroidal space is a rare complication of vitrectomy.The pathway of the migration is most likely through the internal orifice of the sclerotomy sites.Trans-scleral drainage surgery is an effective method to remove the migrated silicone oil from the suprachoroidal space.
