Objective/methods: We present two cases of patients with chronic endophthalmitis. The treatment included intraocular lens exchange, total capsulectomy and posterior vitrectomy through the limbus. In both cases, samples of the vitreous were taken and sent to the laboratory together with the intraocular lens and remmants of posterior capsule for culture and antibiogram.
Results/conclusions: Microbiologic examination and culture were positive in two cases for Bacillus subtilis, which is not actually identified in literature as an etiologic agent for chronic endophthalmitis.
