Infection

An infection in or around the eye may cause a headache over that eye4. Most commonly, the infection occurs in a sinus -- a hollow space within a skull bone. The frontal, maxillary, sphenoid and ethmoid sinuses are all located near the eye. They can become infected with a bacteria, virus or even fungus, producing sinusitis.

Glaucoma can cause a headache over the eye, as well as eye pain.

Increased Intracranial Pressure

Excessive pressure within the skull -- known as increased intracranial pressure -- most commonly produces pain throughout the head. But it can sometimes cause pain over just one eye. Because the skull is made of bones, it is a rigid container so anything that takes up space within the skull can increase the pressure inside it.

Bleeding in or around the brain, brain tumors or an infection within the brain or surrounding tissue are among the various causes of increased intracranial pressure. In addition to a headache, increased intracranial pressure may produce nausea, vomiting, confusion, double vision and decreased level of consciousness. Other neurologic symptoms may also be present, either due to the increased pressure or the underlying cause.

See your doctor to determine the cause if you have headaches that usually occur over just one eye. Seek immediate medical attention if you have a sudden severe headache, any changes in vision, sudden drooping of an eyelid or significant redness or swelling of the eye or surrounding area. Also obtain immediate medical care if you have symptoms of increased intracranial pressure or any other neurologic symptoms, such as weakness, numbness, a seizure or difficulty speaking or swallowing.
