The eye and face pain.
Because face pain may be referred from the eye, all patients with this complaint require a careful eye examination. Pain may also be referred to the eye and surrounding face by other structures innervated by the ophthalmic division of the fifth (trigeminal) cranial nerve. These structures include the paranasal sinuses, orbital contents, optic nerve, and meninges and vessels in the cavernous sinus and anterior cranial fossa.
