Pasteurella multocida endophthalmitis after a cat bite.

We treated a patient with Pasteurella multocida endophthalmitis associated with a retinal detachment resulting from a cat bite. To our knowledge, endophthalmitis from an animal bite has not been described previously. Organisms were directly inoculated from a perforated wound through the globe. The patient was vigorously treated with intensive systemic antimicrobial chemotherapy and pars plana vitrectomy. The inflammation subsided after repeated vitrectomies. A subsequent retinal detachment was treated with fluid-gas exchange and 360 scleral buckling with a silicone implant. Eight months after surgery the visual acuity was 40/200.
