Purpose:
To describe the clinical manifestations and outcomes in 4 patients with endophthalmitis caused by Bacillus cereus and Chlamydia trachomatis.
Setting:
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.
Conclusion:
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.
