Two Different Cases of Stenotrophomonas Maltophilia Endophthalmitis after Cataract Surgery

  • 1Department of Ophthalmology, Inha University School of Medicine, Incheon, Korea. hschin@inha.ac.kr


To report 2 different cases of postoperative endophthalmitis caused by Stenotrophomonas maltophilia after cataract surgery.
A 73-year-old male with diabetes mellitus developed severe pain in the right eye 2 weeks after cataract surgery. The patient was hospitalized with a diagnosis of infectious endophthalmitis, and vitrectomy was performed. Cultures of aqueous humor and vitreous aspirate revealed S. maltophilia. On day 30 after vitrectomy, his visual acuity had improved to 20/20 and there were no recurrences. A 61-year-old female with no significant past medical history was referred for uveitis or delayed onset endophthalmitis 30 days after cataract surgery. An anterior chamber tapping and cultures were performed. S. maltophilia and Aspergillus fumigatus were isolated. The patient received antibiotics and antifungal agents and her visual acuity improved to 20/25.
S. maltophilia has been considered a life-threatening systemic opportunistic infection; however, the organism has recently been reported as an exogenous pathogen of endophthalmitis following cataract surgery. Herein, 2 different cases of S. maltophilia endophthalmitis after cataract surgery are presented and compared with previous case reports.


Aspergillus fumigatus; Coinfection; Postoperative endophthalmitis; Stenotrophomonas maltophilia
