Ocular migraines! Ocular migraines usually affect the vision out of both eyes and the origin is the occipital cortex. Retinal migraines affect the vision out of one eye and the origin is the retina, and will only happen in one eye at a time.
Yes. They often do. This is because of a deviated septum pressing on a complex network of nerves within the nose, wich triggers the migraine. There are other things but you can have them surgically corrected. See: www. Themigrainereliefcenter. Com.
