Pasteurella multocida-induced endophthalmitis after a cat scratch

Abstract

Purpose: To report the case of a Japanese girl with a perforating ocular injury caused by a cat scratch, resulting in Pasteurella multocida-induced endophthalmitis. Observations: A 10-year-old girl presented with a red eye, eye pain, and blurred vision in her right eye immediately after receiving a cat scratch. We performed lensectomy and vitrectomy for endophthalmitis 4 hours after her arrival. After culturing a sample of the vitreous humor, Pasteurella multocida was identified, and the antibiotic was changed to ampicillin. The best-corrected visual acuity of her right eye improved to 20/20 6 months after surgery. Conclusions and importance: We present a rare case of Pasteurella multocida-induced endophthalmitis after a cat scratch. Our findings suggest the great importance of identifying the responsible bacterium and using matched antibiotics as soon as possible in such cases to prevent vision loss.
