“…Apart from optic neuropathies, optic neuritis and acute painful loss of vision (Dshmukh et al, 2007;Dunya et al, 1996;Yoon et al, 2006); associated headache or retrobulbar ache is common. Bilateral involvement has also been reported (Kitigawa et al, 2003).…”

“…Its incidence has been reported to be 51-60% in Asian cadaveric studies (Tan and Ong, 2007;Thanaviratiananich et al, 2003) and is known to be associated with mucoceles, optic neuritis or optic neuropathies (Dshmukh et al, 2007;Dunya et al, 1996;Kitagawa et al, 2003;Klink et al, 2000;Lim et al, 2008;Yoon et al, 2006). We report a case of a 63-year-old lady who developed acute orbital apex syndrome secondary to an orbital abscess that developed from adjacent onodi sinusitis.…”

This article reports the unusual presentation of a patient with an intraconal abscess secondary to sinusitis in an onodi cell in a healthy 63 year old Chinese female. She presented with limited extraocular movements, decreased corneal sensation, rapid drop in visual acuity and signs of optic neuropathy, in the absence of any inflammatory signs in the right eye. MRI scans showed a well-encapsulated mass in the posterior two thirds of the orbit, with the presence of an onodi cell on the right side. She underwent an extended lateral orbitotomy, which revealed frank pus that was positive for Staphylococcus aureus. She was treated with intravenous antibiotics with complete resolution of her presenting signs.

“…The Onodi cell may be poorly aerated and drained, leading to stasis of secretions and recurrent infections. 15 Onodi cell sinusitis may cause visual symptoms because of the proximity of this cell to the optic nerve; a mucocele or pyelocele in an Onodi cell can compress the optic nerve, causing retrobulbar optic neuropathy, 11 optic neuritis, and vision loss. 8,15,16 The Onodi cell may also be mistaken for the sphenoid sinus, resulting in incomplete functional endoscopic sinus surgery in a patient with sphenoid sinus disease.…”

Preoperative recognition of the Onodi cell is necessary to avoid injury to closely associated structures, including the internal carotid artery and the optic nerve. This article describes the central Onodi cell, a variation in which a posterior ethmoid cell lies superior to the sphenoid sinus in a midline position with at least one optic canal bulge. To our knowledge, this anatomic variation has not been previously reported in the literature. Radiographic and endoscopic imaging of this unique variation is provided.

“…In essence any process which is typically associated with the paranasal sinuses may be found within an Onodi cell including infectious or inflammatory sinusitis, fungus ball, inverted papilloma, mucocele or sinonasal malignancy. Given the proximity of the adjacent optic nerve, lesions of the Onodi cell may present with vision changes as the process extends beyond the borders of the cell or expands the osseous margins [6].…”
