Pain in the eye, a common migraine headache symptom
The Mayo Clinic web page for pain in the eye lists the following causes:
· Blepharitis (eyelid inflammation)
· Chalazion (a type of cyst on your eyelid)
· Contact lens problem
· Dry eyes (decreased production of tears)
· Ectropion (outwardly turned eyelid)
· Entropion (inwardly turned eyelid)
· Glaucoma (group of conditions that damage the optic nerve)
· Injury, such as from a blunt trauma or burn
· Iritis (inflammation of the colored part of the eye)
· Keratitis (inflammation of the cornea)
Optic neuritis (inflammation of the optic nerve)
· Scleritis (inflammation of the white part of the eye)
· Uveitis (inflammation of the middle layer of the eye)
Severe headache pain behind one eye which is throbbing, associated with nausea or vomiting, and associated with light and sound sensitivity is usually migraine. Migraine is a trigeminal nerve/arterial problem and branches of the trigeminal nerve and an artery are located behind the eye.
Also “eye strain” or “blurred vision” are rather vague, undefined symptoms and do not usually result from migraine but rather from Tension Type Headache or excessive use of the eyes. I heard a lecture by a professor in neuro-opthalmology say that “The eye is seldom the cause of headache, but all you neurology residents,” he was speaking to a mixed crowd of young neurologists and ophthamologists, “will see thousands of patients who get their eyes checked before coming to see you for their headaches and the eye doctor will find nothing."
This statement may seem outrageous, but I have seen thousands of patients with this pattern.
