%X <B>OBJECTIVE: </B>Intravitreal dexamethasone implant (IID) is an effective and safe treatment for macular oedema as described in the literature. Ocular hypertension and cataracts are the most frequent complications. The indications of IID in the last few years have led to the retrospective reporting of rare complications, with potential visual impact related to the injection procedure.<BR><B>METHODS: </B>A case series is presented of fifteen patients treated with IID for macular oedema who developed non-pharmacological complications related to the injection procedure or the implant itself, including, among others anterior chamber migration, intracrystalline injection, endophthalmitis, or segmentation. Differentiation was made between true complications and those that did not lead to any ocular damage. Epidemiological and baseline data were collected along with the treatment and outcome in each case. An analysis was made of multimodal imaging available.<BR><B>RESULTS: </B>The incidence of complications was 0.65% in this series Anterior chamber migration was the most frequent complication (n=4), followed by intracrystalline injection, and endophthalmitis (n=2). The times between the injection and complications were variable. Visual impairment was the most common symptom (n=6). However, despite the complications found, IID was an effective treatment in most of the reported cases.<BR><B>CONCLUSIONS: </B>Clinicians should be aware of these rare non-pharmacological complications so that they may be prevented and detected early, avoiding irreversible ocular damage.
