The aim of this study was to describe a modified technique of intraorbital irrigation of amphotericin B in the treatment of rhino-orbital mucormycosis. A 38-year-old man was diagnosed with rhino-orbital mucormycosis and subsequently underwent orbital and sinus debridement with postoperative intraorbital irrigation of amphotericin B. Daily irrigation of amphotericin B was infused in the orbit with measures taken to avoid iatrogenic toxicity to the ocular surface and gastrointestinal tract. The use of local amphotericin B irrigation directly in the orbit allowed for local control of infection without orbital exenteration, a good cosmetic outcome and excellent postoperative visual acuity. The published reports on the use of intraorbital irrigation with amphotericin B in mucormycosis infections were reviewed and the technique used at the institution was outlined.
