Abstract
Citrobacter koseri is a bacillus that causes infrequent endophthalmitis. 6% of cultures in endophthalmitis are Gram -, and as in these, C. koseri is associated with a poor visual prognosis. We present a 65-year-old man who works in an animal laboratory. He went to emergencies with loss of vision in his left eye due to a vitreous hemorrhage. A vitrectomy was performed and 3 days later, endophthalmitis was diagnosed. Vancomycin and Ceftazidime were applied in eye drops and in two intravitreal injections. 24 h later he returned with a lens extrusion. Due to the severity of the condition, an evisceration was performed. Subsequently, the samples confirm the microorganism. We assume that the entry point for the bacterium was the sclerotomies through the exposed suture material, after handling rodent feces.
