Preoperative Administration of Amphotericin B in Orbital Mucormycosis Management: A Case Report

This case report presents a 29-year-old male with diabetes mellitus who developed rhino-orbito-cerebral mucormycosis (ROCM) that was successfully treated with liposomal amphotericin B orbital injections. Despite emergent endoscopic debridement, the patient's disease progressed intracranially and intraorbitally, but he declined further surgical intervention. Subsequently, due to rapid acute vision loss, we initiated transcutaneous retrobulbar amphotericin B (TRAMB) injections. Following these injections, visual acuity, motility, and intraorbital fungal burden improved despite intracranial progression. This report highlights the benefits of TRAMB administration in aggressive fungal infections and explores the mechanisms behind its effectiveness, particularly in globe preservation. By targeting the infection in an area with a relatively robust blood supply, TRAMB reduces surgical difficulty and improves overall outcomes.
