We report the case of a patient with allergic fungal rhinosinusitis presenting with vision loss. A 49-year-old man presented to the JCHO Osaka Hospital with acute loss of vision in the right eye. Computed tomography showed bony erosion of the right lateral wall of the Onodi cell, close to the optic canal. Emergent endoscopic sinus surgery was performed. Histopathology revealed eosinophilic mucin in the Onodi cell and the sphenoid sinus. The optic canal was not detected due to the edematous mucosa. After the operation, the patient was treated with a systemic steroid for about 1 month. Based on the clinical and histopathological findings, the patient was diagnosed as a case of allergic fungal rhinosinusitis. With treatment, eventually, the visual loss improved.<br/>Histopathological examination is necessary to confirm the diagnosis of allergic fungal rhinosinusitis. Therefore, when endoscopic sinus surgery is perfoemed, the mucin should be examined to confirm its allergic nature. This disease often recurs, therefore postoperative observation is important.<br/>While no cases of allergic fungal rhinosinusitis presenting with acute blindness have been reported previously from Japan, about 20 cases have been reported from foreign countries. The lesions in this condition mainly involve the sphenoid sinus, orbital apex and the cavernous sinus. No cases with Onodi cells have been reported. We have reported a prevalence of Onodi cells of 26% in our report, and of a pneumatized anterior clinoid process in the Onodi cells of 30%. We need to be aware of the presence of Onodi cells and pneumatized anterior clinoid processes so as to prevent damage to the optic canal.
