Purpose Hydrogel self‐inflating expanders are used since the beginning of the century in order to treat enophalmos that occur after enucleation or evisceration. They are inserted in a dry, contracted state, and expand gradually to reach 10‐fold increase in volume. This procedure is relatively simple and considered as safe. Short term complications are rarely reported. Aim: to report a case of orbital swelling after implantation in order to discuss differential diagnosis and treatment options and present a revue of literature. Methods We describe the case of a 55 years old woman who received intra orbital injection of self‐inflating expanders in order to treat post‐enucleation enophtalmos. This procedure was followed by unexpected orbital swelling one day after surgery. The patient described important pain but no infectious signs were found. Results Early CT scan showed intra orbital isodense mass which ruled out post operative bleedind. MRI allowed to find out oedema features in the mass on T2w‐STIR images. It showed also the expanders inside the mass. The patient underwent topical and oral steroid medication during 3 months allowing complete resolution of the event. With no recurrence after 6 months follow up. After 6 months the swelling totally disappeared and MRI showed only the expanders with a high signal in T2w‐STIR images. Conclusions Non‐infectious orbital swelling after hydrogel self‐inflating expanders had not been previously described. Reporting adverse effects may help oculoplastic physicians improving the management of such rare cases.
