Scotoma. The plural is scotomas or scotomata. These spots may sometimes flicker (such as what happens during a migraine aura), in which case they are referred to as scintillating scotomas. Having a demyelinating disease such as MS raises the potential for developing scotomata.

how long does scotoma last? The visual symptoms typically last approximately 20-30 minutes and then completely resolve. The area where vision is disrupted is known as a scotoma and the whole episode is often referred to as an aura.

In respect to this, what is the biggest problem with a scotoma?

The size of the monocular scotoma is 5×7 degrees of visual angle. A scotoma can be a symptom of damage to any part of the visual system, such as retinal damage from exposure to high-powered lasers, macular degeneration and brain damage.

How do you get rid of scotoma?

Large type books may help a person with a scotoma. Unfortunately, scotomas cannot be corrected by glasses or contact lenses. Sometimes surgery may be helpful in treatment of a scotoma. For example, if the scotoma is caused by a tumor, removal of the tumor may correct the scotoma.
