A man in his mid-20s with a history of left traumatic corneal laceration and open-globe repair presented with hyphema, corneal edema, traumatic aphakia, iris loss, vitreous hemorrhage, and funnel retinal detachment with proliferative vitreoretinopathy. He underwent scleral buckling, anterior chamber washout, penetrating keratoplasty with temporary keratoprosthesis, 23-gauge pars plana vitrectomy, membrane peeling, endolaser, and silicone oil (SO) tamponade with retention sutures placed at the iris plane (Video and Figure, A).1 At 1 month following surgery, intraocular pressure was 15 mm Hg, visual acuity was hand motions, and the retina was attached. High-frequency ultrasonographic biomicroscopy revealed fibrin in the anterior chamber as well as SO interfaces with the aqueous fluid and retention sutures (Figure, B). The concave shape of the SO-aqueous interface is due to high surface tension of the SO against the retention sutures. This finding represents successful sequestration of the SO from the anterior chamber.
