PURPOSE: To report 4 cases of spontaneous Retisert pellet dislocation. DESIGN: Retrospective case series. METHODS: Description of cases. RESULTS: In all 4 cases, the time of Retisert implantation was 3-6 years prior to presentation. One case was complicated by retinal commotio and a retinal tear; another was complicated by corneal endothelial failure, due to dislocation of the pellet into the anterior chamber. CONCLUSION: Spontaneous pellet separation may occur with Retisert as a late complication. It is unclear whether these dislocations are from a manufacturing fault or are related to extended intraocular exposure.
