What is an Ocular Migraine?

Most people have heard of migraine headaches, but did you know you can have migraines in your eyes as well? 

An ocular migraine occurs when changes in the blood vessels in the optic nerve at the back of your eye cause you to experience temporary visual disturbances or distortions. These can include auras, flashing spots of light, or even shimmering zigzags that suddenly appear in your field of vision.  Depending on their severity, the symptoms of an ocular migraine can affect your ability to perform a number of daily tasks, such as using a computer, watching television, reading, writing, or driving.

Ocular migraines are often associated with migraine headaches. Auras and other visual distortions are common symptoms of migraine headaches. However, ocular migraines can occur on their own, and without the pain that usually accompanies a migraine headache.

The Causes of Ocular Migraines are Unknown

Researchers don’t know exactly what causes an ocular migraine.

Should I See an Eye Doctor About An Ocular Migraine?

Despite the unsettling effects they have on our vision, ocular migraines are usually nothing to worry about. Typically, ocular migraine episodes resolve themselves after several minutes and do not require medical treatment. Symptoms can be relieved by closing your eyes, removing yourself from bright light, and taking a break from looking at a screen. 

However, if you have frequent ocular migraines, or are experiencing an increase in their frequency, you’ll probably want to go in for a comprehensive eye exam. Ocular migraines may be a symptom of a more serious medical condition, such as a head injury, brain tumor, arterial problem, infection, or exposure to a toxic substance.

Retinal migraines aren’t the same as ocular migraines. Retinal migraines are much more serious. Rather than visual distortions, retinal migraines can temporarily cause severe vision loss or even blindness in the affected eye. Consult a doctor immediately if you begin to experience symptoms of retinal migraine.
