Endogenous Endophthalmitis due to Multidrug-Resistant Pseudomonas aeruginosa Treated with Colistin: A Case Series

Multidrug-resistant Pseudomonas aeruginosa is being increasingly recognized as a cause of endogenous endophthalmitis in critically ill patients. Three patients were included in this case series. Antibiogram profile in all three cases showed sensitivity to colistin only. All cases were treated with systemic and intravitreal colistin. Although there was clinical improvement, final visual outcome was poor in all cases. Intravitreal colistin can be tried in multidrug resistance cases. Final prognosis depends on early diagnosis and quick institution of appropriate therapy.
