Will Scotoma Go Away?

A scotoma that happens before a migraine headache is temporary and usually goes away within an hour. If the scotoma is on the outer edges of your vision, it usually does not cause severe vision problems.

How long does scotoma last?

Most scintillating scotomas are temporary and last anywhere from a few seconds to up to 30 minutes. Often, they are associated with migraine headaches (and therefore are sometimes called a migraine scotoma). But scintillating scotoma can occur without head pain as well.

How do you get rid of scotoma?

Typically, scintillating scotomas don't require treatment. In most cases, the blind spot will resolve on its own within about an hour. Lying down to rest, closing your eyes, drinking water, and taking an over-the-counter pain reliever, such as ibuprofen or acetaminophen, may help to relieve mild symptoms of scotomas.
