Atropine eye‐drop‐induced acute delirium: a case report

Abstract

Atropine is an anticholinergic drug which is used in both parental and topical routes. Topical eye‐drops of atropine sulfate are used as mydriatic and cycloplegics. Parental atropine‐induced delirium is well known but topical atropine eye‐drop‐induced delirium cases are very limited in literature. In this case report, an elderly man underwent cataract surgery and developed delirium after the use of 1% atropine sulfate eye‐drops as prescribed. This case supports the notion that even atropine eye‐drops can cause delirium in patients at therapeutic doses in elderly.
