Bilateral Orbital Apex Syndrome Related to Sphenoid Fungal Sinusitis.

Orbital apex syndrome (OAS) is a rare condition that usually occurs due to damage to surrounding inner and surrounding bone tissue. Orbital apex syndrome may result from a variety of conditions that cause damage to the superior orbital fissure and to the optic canal leading to optic nerve (II) dysfunction. We recently experienced a rare case of sphenoidal , which damaged the adjacent cavernous sinus structures and led to the definite symptom of bilateral OAS in a 77-year-old male. We present this rare case with a brief review of these disease's entities.
