Successful Treatment of Acute Endophthalmitis after Cat Bite: A Case Report and Review of the Literature

Endophthalmitis after cat bite has poor outcome particularly those associated with scleral injury. A 33-year-old Caucasian female was seen by her ophthalmologist 4 days after cat bite to her right eye with hand motion vision and obvious signs of acute endophthalmitis. She was treated with exploration and repair of scleral puncture wound, anterior chamber and vitreous cultures and intravitreal injections of vancomycin and ceftazidime. Cultures were positive for alpha hemolytic Streptococcus . She underwent a pars plana vitrectomy, cultures and repeat injection of the same antibiotics and intravitreal dexamethasone 2 days later. Cultures grew Bacillus . Endophthalmitis resolved and she regained 20/20 vision after cataract surgery 3 months later. Successful outcome of acute endophthalmitis following a cat bite to the sclera in this case was most likely due to prompt intravitreal antibiotics and early vitrectomy combined with supplemental intravitreal antibiotics and steroid therapy.
