Background: The aim of this study was to report an unusual case of chronic postoperative endophthalmitis following cataract surgery, secondary to Ochrobactrum anthropi that was found to be resistant to vancomycin.
Findings: Anterior chamber paracentesis cultures grew gram negative bacilli Ochrobactrum anthropi. The patient was treated with a series of intracameral injections of moxifloxacin, with adjuvant oral moxifloxacin. Posterior sub-Tenon and oral corticosteroids were used to treat cystoid macular edema. Explantation of the intraocular lens (IOL)-capsular bag complex was avoided.
Conclusions: Chronic postoperative endophthalmitis is a rare entity, often due to indolent pathogens that sequester in the capsular bag. Aggressive surgical intervention may be avoided with the use of adequate intraocular antibiotic, provided that the offending organism demonstrates appropriate antibiotic susceptibilities.
