Aim:
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.
Conclusion:
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.
