BACKGROUND: The study aims to describe an inadvertent sub-macular triamcinolone acetonide (TA) deposition following a TA-assisted pars plana vitrectomy (PPV) for epiretinal membrane (ERM) peeling.

CASE REPORT: In this interventional case report, a 75-year-old female with ERM-induced visual distortion underwent TA-assisted 25-gauge three-port PPV, endolaser photocoagulation, and sulfur hexafluoride (SF6) gas (8%) endo tamponade to treat ERM in the left eye. Significant TA deposition was observed intraoperatively in the submacular region, which remained after ERM and internal limiting membrane (ILM) removal. One month after PPV, the retina appeared flat, with no significant vitreoretinal interface defects or macular ultrastructural abnormalities. Vision improved from 0.40 to 0.2 logMAR, and there was no evidence of any ophthalmoscopic damage.

CONCLUSIONS: Inadvertent sub-macular TA deposition following ERM peeling did not cause any significant surgical sequelae.
