title: Postoperative endophthalmitis caused by Bacillus cereus and Chlamydia trachomatis.
abstract: OBJECTIVE
  To describe the clinical manifestations and outcomes in 4 patients with endophthalmitis caused by Bacillus cereus and Chlamydia trachomatis.
  
  
  METHODS
  Department of Ophthalmology, Ankara Training and Research Hospital, Ankara, Turkey.
  
  
  METHODS
  Four patients who had cataract extraction and intraocular lens implantation with phacoemulsification at a secondary eye-care center presented with endophthalmitis. Cultures and direct fluorescein assay (DFA) were performed on vitreous aspirates from all patients.
  
  
  RESULTS
  Cultures were positive for B cereus and DFAs were positive for C trachomatis in all patients. Despite timely intervention, at the end of follow-up, 1 patient had 20/200 visual acuity and another, counting fingers at 3 m. Phthisis bulbi developed in the 2 other patients.
  
  
  CONCLUSIONS
  The course of infection with B cereus and C trachomatis poses a potential threat, especially because of the limited data on treatment of endophthalmitis secondary to C trachomatis.
