Endophthalmitis Caused by Alcaligenes Faecalis: A Case Series

Abstract

Purpose: To profile the etiology, clinical outcomes and drug sensitivity patterns in endophthalmitis caused by Alcaligenes faecalis.

Methods: Retrospective analysis of all the cases of A. faecalis endophthalmitis presenting to tertiary referral care ophthalmic hospital in Eastern India from January 2009 to December 2012 was done.

Results: A total of five cases were included in the study. Out of the five cases, one was of endogenous origin and the rest were post cataract surgery. All but one case underwent vitreo-retinal surgical intervention followed by intravitreal antibiotics. Alcaligenes faecalis was isolated in all the cases. Sensitivity to ceftazidime, aminoglycosides and ciprofloxacin was 20%, 60% and 80%, respectively. Two patients attained a final visual acuity of 6/24. One eye became phthisical in due course.

Conclusion. Alcaligenes faecalis is a very rare cause of endophthalmitis. Aminoglycosides and fluroquinolones can be considered as main line of treatment.
