Abstract:

Macular infarction due to intraocular aminoglycoside injection is well known. Recently, few atypical organisms have been reported to cause macular infarction after endophthalmitis. Our case is a 69-year-old female patient who presented with redness and discharge in the right eye. She had had intraocular ranibizumab injection for diabetic macular edema two days ago. The vision was counting fingers at one meter without a clear view of the fundus. The patient underwent vitreous tap, and intraocular injection of vancomycin and ceftazidime was performed. The vitreous culture was positive for Klebsiella pneumoniae. Two days later, fundus visibility was better. However, the vision was counting fingers at 50 centimeters, and macula was pale. Therefore, we planned pars plana vitrectomy. Klebsiella pneumonaie is generally considered to be a cause of endogenous endophthalmitis, especially in patients with liver abscess or fulminant pneumonia. We herein wanted to report the first case of Klebsiella pneumonaie endophthalmitis with no endogenous focus resulting in macular infarction.
