Serratia rubidae endophthalmitis following penetrating ocular injury

A 10-year-old boy incurred penetrating trauma to his left eye by a small piece of wood. Immediate lens aspiration and repair of his corneal laceration were performed. The patient, however, demonstrated "persistent severe uveitis." On the fourth day following his injury, an uncomplicated pars plana vitrectomy was performed in combination with intracameral injection of gentamicin, cefazolin, and dexamethasone. Cultures of the vitrectomy specimen demonstrated Serratia rubidae. Postvitrectomy treatment with parenteral gentamicin, cefazolin, prednisone, and oral trimethoprimsulfamethoxazole resulted in a complete cure of the endophthalmitis and retention of good visual function. This patient represents the first reported case of Serratia rubidae endophthalmitis.
