RESUMEN
PURPOSE: To demonstrate the presence of emulsified silicone oil (SO) droplets in the canal of Schlemm with anterior segment optical coherence tomography (AS-OCT). METHODS: AS-OCT images from an eye that had undergone retinal detachment (RD) surgery three years ago were reviewed. At the time of surgery, SO had been used as the tamponading agent. RESULTS: The AS-OCT images demonstrated that minute emulsified SO droplets were present in the canal of Schlemm. CONCLUSION: Retention of SO in the eye for an extended period of time after RD surgery leads to secondary glaucoma. Presence of minute emulsified SO droplets in the canal of Schlemm may contribute to this process.

A 54-year-old male sustained ocular trauma with a projectile. Examination of the right eye revealed an intraocular foreign body (IOFB) adjacent to the optic nerve head, vitritis, vitreous hemorrhage, and translucent perivascular sheathing of the retinal vessels in all quadrants suggesting frosted branch angiitis (FBA). The patient underwent vitrectomy with removal of the IOFB and silicone oil tamponade under steroid cover. With continued use of systemic and topical steroids after surgery, complete resolution of FBA and improvement in vision were noted in a week. Prompt resolution of FBA after IOFB removal points toward a strong association between the presence of IOFB and FBA.
