Late-onset persistent Descemet's membrane detachment following uncomplicated clear corneal incision cataract surgery

Abstract

We report the case of a 76-year-old man who developed a late-onset Descemet's membrane detachment (DMD) 5 months after uncomplicated cataract surgery. Despite two air tamponade procedures that initially appeared successful, the DMD continued to return. After careful examination it was found that a surgical entry wound may have been scarred open (fish-mouthing), which continually promoted Descemet's membrane to detach. Excision of the abnormal scar led to an almost complete resolution of the DMD. To our knowledge, this is the first report of a pathological (fish-mouthing) entry wound causing a persistent, late DMD. We discuss the reasons why the management of late DMDs requires careful consideration.
