Orbital complications of sinus disease continue to appear in clinical practice. Acute visual loss may occur in association with sinusitis either as a complication of orbital cellulitis or, less frequently, as a part of the orbital apex syndrome. The classification which defines the degree of orbital extension is valuable, therapeutically and prognostically. The orbital apex syndrome is associated with an affection of the vessels and nerves passing through the superior orbital fissure and the optic foramen and characterized by visual loss and ophthalmoplegia. But it has minimal or no signs of orbital inflammation such as proptosis, chemosis, or lid edema. We experienced a case of temporary monocular visual loss and ophthalmoplegia caused by mucocele in the sphenoid sinus. Thus, we report, with a review of literature, a case of orbital apex syndrome caused by mucocele in the sphenoid sinus in a 53 year-old male patient.
