Bilateral dead bag syndrome in skeletal dysplasia: A case report and review of literature

Abstract

Posterior chamber intraocular lens (IOL) dislocation is a rare yet grave complication of cataract surgery. Late in-the-bag IOL dislocation is usually spontaneous and occurs due to progressive zonular weakness. Aging, high myopia, pseudoexfoliation, vitrectomized eye, and connective tissue disorder are the predisposing factors. A floppy capsular bag without any proliferative deposits has been termed a “dead bag.” Bilateral in-the-bag IOL dislocation or dead bag syndrome is very infrequent. We present such a case in a 67-year-old male with skeletal dysplasia. The patient had undergone uneventful cataract surgery in both eyes 11 years and 6 years ago respectively. Skeletal dysplasia may cause zonulopathy and associated defective collagen synthesis can affect the anchorage points of the zonules. In these patients, cataract surgery should be accomplished by experienced surgeons after detailed counseling of such complications.
