PURPOSE: To describe a patient with compressive optic neuropathy caused by a mucocele in an Onodi cell. DESIGN: Interventional case report. METHODS: A 73-year-old man complained of sudden visual loss in the left eye 10 days after cataract surgery. Coronal computed tomography showed a homogeneous mass in an Onodi cell. Magnetic resonance imaging revealed an oval-shaped lesion that compressed the left optic nerve. RESULTS: After endoscopic microsurgery of the paranasal sinus, visual acuity in the left eye improved. Histopathological examination of the excised specimen showed a mucocele. CONCLUSIONS: Ophthalmologists should be aware that the mucocele in the Onodi cell, an anatomical variation of the paranasal sinus, may compress the optic nerve.
