Some rare types of migraines can cause temporary paralysis or blindness, and can even mimic some very serious medical conditions. More than 13 percent of Americans are affected by migraines, severe pain in the head that is sometimes accompanied by vision problems, nausea, vomiting, and dizziness.
Warning signs of an ocular migraine include: Vision problems that affect one eye, such as flashing lights, blind spots in your field of vision, or blindness. You might have them for only a few minutes or up to 30 minutes. These problems affect just one eye, which makes ocular migraines different from other types. It can be hard to tell the difference between flashing lights or blindness in one side of your vision -- but involving both eyes -- and having these symptoms in only one eye. If you canât tell, cover one eye and then the other.
