Transcutaneous Retrobulbar Amphotericin B Injection Treatment for Invasive Fungal Rhino-Orbital Sinusitis: A Case Report.
Article in Case reports in ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Invasive fungal rhino-orbital sinusitis is a rare and life-threatening condition that occurs in immunosuppressed patients. This article aimed to describe the case of a patient with bilateral orbital mucormycosis treated with right orbital exenteration and transcutaneous retrobulbar amphotericin B (AMPB) in the left orbit. Case Presentation: A 61-year-old diabetic woman, immunosuppressed due to treatment with immunotherapy for breast cancer and systemic corticosteroid for sarcoidosis, was admitted to our hospital with complaints of severe headache, fever, and complete right visual loss. Imaging exams demonstrated an invasive pansinusitis with right orbital apex involvement, extension to frontal cerebral space and an inflammatory swelling in the medial aspect of the left orbit with extra-conal extension. These findings corroborated the diagnosis of rhino-orbital mucormycosis with intracranial extension. Initial treatment included systemic antifungal therapy and necrotic tissue debridement, both encephalic and sinonasal. Since there was a complete right orbital apex and optic nerve involvement, she was treated with right orbital exenteration. The left eye presented good visual acuity (8/10 Snellen chart) and no signs of afferent or efferent pathway involvement. Regarding the left orbital soft tissue involvement, this patient was proposed to transcutaneous retrobulbar injections of 1 mL of 3.5 mg/mL of AMPB. She received a total of 6 injections, with clinical stability and radiographic signs of improvement regarding the left orbital involvement of the infection. Conclusion: Transcutaneous retrobulbar injection of AMPB seems to be a valid approach for specific cases of rhinosinus mucormycosis with orbital invasion, allowing for orbital preservation without compromising patient survival.
