The purpose of this post is to define the difference between “classic” and ocular migraines. Also, before I launch into specifics, I would like to start with this:
Flashing lights in your eyes can be concerning, as they can be a sign of retinal detachment or other retinal problems. It is essential to see an ophthalmologist if you have flashing in your eyes. An eye exam can reveal problems with the vitreous fluid, the retina, or even signs of a stroke.
Now, let’s talk about migraines. This blog talks about two types:
“Classic” Migraines are thought to be caused by spasm of blood vessels in the brain. If this happens in the temple area, the result can be a severe, one-sided headache, sound sensitivity, nausea, and vomiting.
If, on the other hand, the spasm of blood vessels occurs in the back of the brain where vision is processed, this could be an Ocular or Eye Migraine. This condition can be one cause of visual disturbances that often do not need treatment. However, it’s still essential to have a complete eye evaluation to rule out more serious causes.
Symptoms vary from patient to patient or even from one episode to the next. Signs can involve shimmering light, heat-wave effects, jagged black and silver arcs, white-out areas, or blank patches. Often the visual symptoms last between 5 and 60 minutes and can change during this period. Anxiety and mild disorientation are also common during the episodes. Also, a mild headache that lasts several hours can occur. It’s common for patients to have two or three episodes within a short number of days, then have no symptoms for months.
Ocular Migraine Triggers and Treatments
Triggers of ocular migraines can include caffeine, chocolate, red wine, blue cheese, nuts, and processed meats. Stress or release of tension, bright lights, and exercise can also be triggers.
Treatments are often unnecessary because the visual disturbance only lasts for a short time, and the headaches aren’t severe. Some people find that taking an aspirin at the onset of their symptoms can prevent the headache altogether. While caffeine can cause eye migraines in some people, for others sipping a small amount of a caffeinated beverage can stop the symptoms.
It is important to stop driving if you experience any visual effects. If these symptoms last more than an hour, this can be a sign of something more serious, and you should seek medical attention immediately.
