To describe the clinical manifestations, treatment results, and antibiotic susceptibility in 6 cases of Stenotrophomonas maltophilia endophthalmitis. METHODS: We retrospectively reviewed 6 eyes of 6 patients who were diagnosed with Stenotrophomonas maltophilia endophthalmitis. Specifically, we considered each patient's age, sex, past history, visual acuity, hypopyon, treatment, and prognosis. RESULTS: For our study, we considered patients treated during the period of January 2008 to December 2015. Stenotrophomonas maltophilia (6 eyes) was the second most common gram-negative bacteria cause of total bacterial endophthalmitis while Pseudomonas aeruginosa (14 eyes) was the most common gram-negative bacteria cause during the same period. Visual disturbance was the dominant symptom being found in all 6 patients. Other symptoms include ocular pain and hypopyon. The initial visual acuity was light perception (1 patient), hand motion (3 patients), finger count (1 patient), and 0.02 (1 patient). Excluding the 1 patient with light perception, the mean initial visual acuity was logMAR 1.72 (Snellen equivalent; 20/1,049). Overall, 5 patients underwent vitrectomy and intravitreal antibiotics injection, while, the remaining other patient was treated with intravitreal antibiotics injection, followed by vitrectomy. All 6 patients showed sensitivity to Ceftazidime and Levofloxacin and 2 patients showed sensitivity to Trimethoprim/Sulfamethoxazole. CONCLUSIONS: Stenotrophomonas maltophilia endophthalmitis was the second most common gram negative organism to cause endophthalmitis after cataract surgery. All 6 of the tested isolates were found to be sensitive to ceftazidime and levofloxacin. Urgent treatment outcomes were similar to previous reports.
