Headaches and Your Eyes CT - Possible Causes

We all experience headaches every now and then. Sometimes, because a headache seems centered behind or around the eyes, it may feel as though the cause is somehow ocular in nature. The truth is, most headaches are caused by other factors. In instances where the eyes are indeed the source of a headache, treatment is typically quite simple. Let's take a look at some of the ways eyes may instigate headaches.

• Contact lens discomfort. Although contacts are a safe way to improve vision, they are not without risk. Some patients experience headache due to a poorly fitting contact lens. More commonly, however, there will be an aching directly in the eye. This lens may be too tight, or may decrease the amount of oxygen that is able to reach the cornea.
• Conjunctivitis. Also known as "pink eye", this infection of the membrane over the sclera (the "white of the eye") is typically either caused by a virus, or by bacteria. This infection is highly contagious and treatment is necessary. Even during the course of treatment, a patient may experience red itchy eyes and headache. In the presence of any ocular infection, contact lens wear must be immediately discontinued.
• Corneal abrasion. The cornea is the clear portion of the eye which we see through. Should this delicate ocular layer be injured, it becomes highly sensitive. Patients typically say they feel as though a rock is moving around in their eye when a corneal abrasion has occurred. Examination with Dr. Gold is important in order to assess the injury and to rule out the presence of a foreign body. Typically, corneal abrasions will heal quickly with the help of antibiotic ointment and an eye patch. It is important to seek treatment so to avoid another common cause of headaches, corneal ulcer.
• Corneal ulcer. A corneal infection is caused by bacteria that gain entry to the cornea through a scratch or breakdown in the corneal surface, such as a corneal abrasion. This condition causes severe eye pain and may also cause headache. Also associated with corneal ulcer are tearing, foreign body sensation, sensitivity to light, and blurred vision. This is a very serious condition that requires early treatment in order to protect vision.

These are just a few of the ocular instigators of headaches. As mentioned, most headaches have non-ocular causes. However, seeking an ophthalmic examination to assess the health of your eyes is the best way to maintain vision and well-being.
