An Unusual Case of Endogenous Klebsiella Pneumonia Endophthalmitis

ABSTRACT

PURPOSE: To report an unusual case of endogenous endophthalmitis in a patient with Klebsiella pneumoniae primary liver abscess. CASE SUMMARY: A-54-year-old man with diabetes mellitus and liver abscess was referred to us for consultation of visual loss in his left eye for 2 days. On the first examination, the patient's left visual acuity was hand motion and the left intraocular pressure was 13 mmHg. Vitreous opacity and inflammatory membrane were detected with increased echogenicity using ultrasonography. Vitectomy and intravitreous antibiotic injection were performed under the impression of endogenous endophthalmitis caused by liver abscess on the day of the first visit. Culture revealed Klebsiella pneumoniae from blood and liver abscess. After vitrectomy, the patient showed improvement. However, on the 20th and 40th postoperative days, the patient complained of blurred vision, and inflammation and hypopyon were observed in the anterior chamber. An intracameral antibiotic injection and anterior chamber washing were performed. The patient has not complained of any other symptoms to date. CONCLUSIONS: In this patient with endophthalmitis, inflammation and hypopyon in the anterior chamber were evident three times after vitrectomy. Ultimately, the inflammation was effectively controlled by intracameral antibiotic injection and anterior chamber washes.
