Mucoceles of the posterior ethmoidal and sphenoidal sinuses are rare. Onodi cell mucoceles that cause compressive optic neuropathy are even rarer. We discuss the clinical presentation, radiologic features, and treatment in 2 cases of Onodi cell mucoceles in which the patients presented with loss of vision due to compressive optic neuropathy. These 2 cases demonstrate the importance of interdisciplinary cooperation between the ophthalmologists and otorhinolaryngologists, as prompt medical and surgical intervention can result in the return of vision in this uncommon but treatable condition.
