A 17-year-old boy presented with intermittent left eye pain. He had undergone traumatic retinal detachment repair with vitrectomy and silicone oil tamponade 1 year before. At presentation, his visual acuity was 20/80 OU and his intraocular pressure was elevated at 41 mm Hg (normal, <21 mm Hg). Examination results revealed emulsified silicone oil droplets in the anterior chamber forming an oil-fluid interface with the aqueous humor, creating the appearance of an “inverted hypopyon” (Figure, A). He underwent surgical removal of the silicone oil (Figure, B), with resolution of his ocular hypertension at 1 month after surgery.
