A case of optic disk neovascularization is reported in a 30-year-old female heroin addict with suspected fungal endophthalmitis treated with an intravitreal injection of amphotericin B and fluconazole (200mg/day). Membrane healing was characterized by densification and contraction leading to tractional retinal detachment; excision by vitrectomy was required. Electron microscopy analysis of the membrane removed the tenth month revealed a poorly vascularized fibrous tissue infiltrated by chronic inflammatory cells. Visual improvement was poor owing to a postoperative macular disorder and a full-thickness retinal scar.
