RESUMO
PURPOSE: To report two cases of spontaneous Retisert implant dissociation with dislocation of the medication reservoir into the anterior chamber. DESIGN AND METHODS: Case reports. RESULTS: Two patients with chronic, noninfectious uveitis following Retisert implantation between 6 and 7 years prior presented with a complaint of a "white spot" in their right eyes. Both patients had previous pars plana vitrectomies. Anterior segment examination revealed a dislocated medication reservoir of the Retisert implant in the inferior portion of anterior chamber with associated reservoir-corneal endothelial touch and stromal edema. The reservoirs were subsequently retrieved via a pars plana approach and removed from the anterior chamber through a corneal incision. CONCLUSIONS: Spontaneous dissociation of the Retisert implant with dislocation of the medication reservoir into the anterior chamber can be a late complication of Retisert implantation. Eye care professionals and patients should be aware of this complication, particularly with long-term intraocular retention of this device.

A human immunodeficiency virus-negative 63-year-old male with autoimmune hemolytic anemia presented with decreased vision, photophobia and hearing loss. After initial testing seemed consistent with sarcoidosis, he was found to have disseminated Cryptococcus with a cryptococcoma of the left eye. Treatment with systemic anti-fungal therapy improved the patient's condition.
