Abstract

Rhinogenic optic neuropathy (RON) results from ethmoid or sphenoid sinus inflammation or infection causing optic nerve impairment.1 Treatment often requires endoscopic surgery and vision restoration occurs in select cases. There is no clear evidence for the benefit of optic nerve decompression (OND) in these situations. We present a unique case of RON caused by an Onodi cell mucocele for which isolated endoscopic mucocele drainage was not enough and further OND was needed to improve vision.
