Clostridium difficile Colitis after Topical Ophthalmic Use of Levofloxacin / 이화의대지

ABSTRACT

Clostridium difficile colitis (CDC) has been associated with virtually all available antibiotics. It is well known that administration of drugs by the ocular route can result in systemic absorption with the possibility of systemic effect. We report a case of a 74-year-old woman who was treated with 0.5% levofloxacin eyedrops for ten weeks running for the post operative management of two separate bilateral cataract surgeries. Toxin assay for C. difficile was positive and the endoscopic findings were compatible with CDC. The plasma concentrations reached after intraocular administration of levofloxacin seem so trivial, but the administration of topical agents could make accumulated effect and be a potential cause of systemic toxicity.
