Abstract
|
|
|
|
Acute optic neuropathy occurs commonly as a result of ischemia and inflammation, but paranasal sinus disease without infection is generally dismissed. We report a rare case of acute optic neuropathy caused by compression of a mucocele in an Onodi cell, which is an uncommon anatomical variation of the ethmoid sinus. The mucocele was confirmed by imaging and endoscopic sinus surgery. An Onodi-cell lesion should be considered in the differential diagnosis of acute optic neuropathy.
