title: Chronic cystoid macular edema in an eye with a capsule defect and posteriorly dislocated capsular tension ring.
abstract: A 72-year-old man presented with visual deterioration and cystoid macular edema (CME) 9 months after cataract surgery elsewhere. A slitlamp examination showed a large posterior capsule defect and a slightly decentered intraocular lens (IOL). In addition, a curved poly(methyl methacrylate) (PMMA) haptic-like structure was seen behind the IOL in the superoanterior vitreous cavity. The foreign body was entangled by vitreous fibers and moved in accordance with ocular motility. A broken PMMA haptic was suspected. During vitrectomy for removal of the suspected IOL haptic, an intact, posteriorly dislocated capsular tension ring (CTR) was found. It was cut in 2 and excised carefully via the sclerectomies. Postoperatively, the CME resolved and vision improved.
