What is an Ocular Migraine?

An ocular migraine, also known as a retinal migraine, occurs when you experience an episode of vision loss in one eye in association with a headache. The visual issues that present are typically temporary and last less than one hour; however, they can mimic other serious eye conditions, so it is important to see an eye doctor to ensure that there is nothing more serious at

play.

Some visual issues that can occur during an ocular migraine include:

 A visual aura or blind spot

 A flickering or moving aura

 Zigzagging patterns

 Shimmering or flickering lights

 Floating lines

Ocular migraines can start as early as 7 years, though most people experience them beginning in their 20s with a peak age of 40. Ocular migraines often come on suddenly and will almost always affect the same eye when they come on.

Ocular migraines differ from migraines with aura. Migraines with aura impact both eyes and the visual symptoms can last longer compared to an ocular migraine.

Though there is not always a direct cause to ocular migraines, it is believed that they happen when blood vessels in the eyes suddenly narrow, restricting blood flow. Other triggers believed to cause ocular migraines include:

 Stress

 Caffeine and alcohol

 Dehydration

 Smoking

 High blood pressure

 Bending over

 Low blood sugar

 Some hormonal contraception

If infrequent, ocular migraines often do not require treatment. If they are experienced more than once a month, they can be treated as you would medically treat a migraine. It is also suggested to try to avoid any potential triggers that may lead to migraines, as listed above. If you are struggling to understand what is triggering your migraines or ocular migraines, it can be helpful to keep a headache journal including information about what you were doing, eating, and any medications that were taken before or after a headache occurs.
