Migraine

Not always a headache

Migraines are notorious for the severe headaches that can occur. But not everyone who has migraines has headaches.

Classic migraine occurs when a person has a visual aura followed by a headache. The headache may vary intensity, from mild to severe. The visual aura may consist of seeing lights or zig-zag lines, or there might be dark or missing areas in the vision. In classic migraine, these visual phenomena occur in both eyes.

There are people who have acephalgic migraine. These are classic migraines, with the vision of both eyes being affected, but without an associated headache.

Retinal migraine occurs when the vision in only one eye is affected, and there is no associated headache.

Sometimes people think that there is a problem with the vision in one eye, when actually there is a problem with one half of the vision of each eye.  Whenever there is a problem with the vision, it is important to determine if the problem is with only one eye, or with half of the vision of both eyes. Covering one eye, and then the other, might help to determine if only one or if both eyes are affected.
