ACUTE UNILATERAL OPTIC NEUROPATHY SECONDARY TO ONODI CELL MUCOCELE: A CASE REPORT
Abstract
Introduction: Optic neuropathy refers to damage or impairment of the optic nerve, which can result in vision loss. Onodi cell mucocele is a rare condition that can lead to optic neuropathy and other health-threatening complications. Here we present a case of successfully treated unilateral optic neuropathy secondary to Onodi cell mucocele associated with chronic sinusitis.
Case report: A 45-year-old woman presented with a 4-day history of right eye pain associated with decreased vision and photophobia with chronic nasal obstruction. Physical examination showed pain on downward extraocular muscle movement, vision acuity of 6/60 and 6/9, and right eye Relative Afferent Papillary Defect (RAPD). CT scan findings led to the diagnosis of right optic neuropathy secondary to Onodi air cell mucocele. Emergency endoscopic sinus surgery was successfully performed in the form of anterior and posterior ethmoidectomy and bilateral sphenoidotomy with drainage of Onodi cell mucocele to release pressure on the optic nerve.
Conclusion: Overall, optic neuropathy from Onodi air cell mucocele is a rare but serious complication that requires prompt diagnosis and treatment to prevent permanent vision loss. This case report details the clinical and radiological presentation and management of Onodi cell mucocele and associated optic neuropathy, highlighting the need for healthcare providers to consider it, especially in patients with optic neuropathy and chronic sinusitis.
