10/8/07 #10 - Ocular Migraines, aura, and blood flow?

Ask the Clinician Health Pro
  • Full Question:
    I have been reading profusely about Ocular Migraines.....which I believe I have had for about 9-10 years. However, I have one symptom which is not as common as all the symptoms I have researched. I usually have the aura in both eyes, from beginning to end lasting for exactly 15 minutes. Most of the literature states that these are seen usually in one eye. My concern is that it is explained in the articles these Migraines are caused by an interruption in the blood flow to the brain. Is this the usual cause? I intend to seek an examination with a Neurologist in the near future, but thought I'd ask about the auras and blood flow at this time. Pat

    Answer:

     

    Dear Pat;

     

    One problem here is that there is no diagnosis of "Ocular Migraine" in the International Headache Society's classification, which is the universally accepted standard. Thus, we can't be sure what you've been reading and what symptoms you think are part of so-called Ocular Migraines. There IS a diagnosis of "Retinal Migraine," in which there are visual symptoms affecting only one eye, followed by a headache and other associated Migraine symptoms within 30 minutes. For more information about "Ocular Migraine" so you can talk to your doctor about your diagnosis, take a look at Ocular, Optical, and Opthalmic Migraines.

     

    As for interruption of blood flow, I'd suggest being a bit more particular about your sources of information, as at least part of what you've been reading is incorrect. As part of the chain reaction that occurs when we encounter a Migraine trigger, the blood vessels constrict for only a fraction of a second, then DILATE.

     

    Good luck,
    John Claude Krusz and Teri Robert
