title: Silicone oil emulsification in the anterior chamber after vitreoretinal surgery.
abstract: BACKGROUND
  The use of silicone oil as an endotamponade for the treatment of complicated retinal detachment is common, but long-term complications can occur if the oil is not removed later. This article documents a case of emulsified silicone oil migration into the anterior chamber after vitreoretinal surgery and provides a discussion and review of common anterior segment complications from this condition.
  
  
  METHODS
  A 59-year-old man reported to the eye clinic complaining of a "growth" over his right eye that had increased in size over the last month. Slit lamp examination found a "reverse pseudohypopyon" in the right eye, which was actually emulsified silicone oil that had migrated from the posterior chamber after a previous retinal detachment repair. The patient was referred for surgical removal of this oily obstruction. Although surgical treatment was delayed for 18 months, his vision improved and his intraocular pressure was lowered through surgical and medical management.
  
  
  CONCLUSIONS
  The use of silicone oil as an endotamponade in cases of complex retinal detachment has become common, but it also may lead to postoperative complications if it is not surgically removed later. This case highlights possible complications from the migration of emulsified silicone oil into the anterior chamber and illustrates the importance of follow-up care for every ophthalmic surgical procedure.
