Intraocular intrusion of a scleral sponge implant

Abstract

A patient with intrusion of a scleral sponge implant after retinal reattachment surgery is described. Retinal incarceration occurred during primary retinal reattachment surgery and the patient underwent additional cryopexy and radial sponge implant. However, the retina remained detached and pars plana vitrectomy was performed with silicone oil endotamponade to reattach the retina. The interval between placement of the sderal buckle and development of intrusion was 3 months. The buckle was sutured to the sclera with mattress sutures. During the postoperative follow-up period, the intraocular pressure was elevated and controlled with topical antiglaucomatous medication. The encircling band was cut but left in place to avoid perforation, and the retina remained attached. Intrusion of a buckle after retinal reattachment surgery is a rare complication that usually does not require surgical intervention. Cutting the silicone band without removing it may be a treatment option.
