What causes migraine?

Do you suffer from Migraines? Have you considered that your eyes could be a cause of your migraines?

Eye Strain

Just like the muscles in your body, your eyes can get tired. For the job they do, your eyes contain the strongest muscles in your body. But as strong as they are, they can become strained and fatigued by sitting in front of a computer, under fluorescent lights, or in front of a TV for a couple of hours. This is called visual fatigue.

Migraines are horrible. For those of you who have never experienced a migraine, you’re one of the lucky few. There’s the pain, of course- throbbing, pounding pain. But then you get the tag along symptoms, nausea and sensitivity to light and noise. Migraine sufferers quickly learn on the second or third migraine that visual symptoms like wavy lines, flashing dots, and temporary blindness are usually the first sign of a migraine. Also, not all migraines are the same:

  1. Regular migraines – can include an aura, which can involve flashing lights and blind spots in the vision.
  2. Retinal, or eye migraines can occur with or without the accompanying headache, but they can still be just as painful.
  • Retinal migraines, or ocular migraines are caused by the same inflammation as regular migraines.  Inflammatory substances are released deep inside the brain and around the blood vessels of the head and brain.
  • While both Ocular and Regular migraines affect vision, ocular migraines usually only affect one eye. Ocular migraine sufferers also typically have a family history of migraine headaches.

What causes ocular migraine?

  • The primary cause of ocular migraine is genetics. If you have a family history of migraine headaches, it is possible that you will develop ocular migraine.
  • Some feel that the problem is related to spasms in blood vessels in the retina, the delicate lining in the back of the eye. Covering one eye and then the other can help to determine if your problem is affecting one eye or both.

Ocular migraines don’t all came with severe pain! The temporary visual disturbances that affect either one or both eyes can be painless.

If you experience unusual vision symptoms, you should schedule a comprehensive eye exam with an optometrist or ophthalmologist to rule out vision-threatening conditions such as a detached retina, please. contact us.
