Enterobacter amnigenus endophthalmitis

Abstract Purpose— To describe a case of Enterobacter amnigenus endophthalmitis. Methods— A 33 year-old, previously healthy man, presented with a unilateral hypopyon uveitis.Visual acuity in the affected eye was counting fingers. Initial laboratory work-up was negative.Vitreous cultures revealed the offending agent. Results— The patient was treated with intravenous and intravitreal antibiotics and respondedwell. Final visual acuity was 20/30. Conclusions— Enterobacter species have been rarely reported as causes of endophthalmitis. E.amnigenus is almost never pathogenic in humans and previous cases have been described inimmunocompromised individuals. Our case demonstrates that appropriate treatment of E.amnigenus endophthalmitis in an immunocompetent individual can result in a good visualoutcome. Keywords endophthalmitis; Enterobacter; trauma; uveitis Introduction Infectious endophthalmitis is a serious intraocular infection with potentially devastatingvisual sequelae. The majority of cases result from exogenous sources following penetratingtrauma or intraocular surgery. Endogenous endophthalmitis occurs via hematogenous spreadof bacteria from a remote primary focus. We present a case of Enterobacter amnigenusendophthalmitis, an organism that has not, to our best knowledge, been previously reportedas a cause of endophthalmitis.
