Bilateral compressive optic neuropathy secondary to bilateral sphenoethmoidal mucoceles.

We have presented a rare case of bilateral posterior sphenoethmoidal sinus mucoceles with bilateral compressive optic neuropathy. While the duration of compression was variably present over a 10-month period, there were nevertheless significant improvements in visual acuity of the right eye and visual fields bilaterally following extensive optic nerve decompression.
