WebWhat is a Scotoma? Commonly mistaken as eye floaters, scotomas (pronounced skuh-TOE-muhs) are an “aura” or blind spot that blocks part of your vision. This vision impairment can appear in the form of a dark spot, or a flicker of light/dark, and it can be either permanent or temporary- depending on what caused your scotoma in the first place.

If it's one eye only, or one at a time, it's more likely inside the eye, where neurologists don't usually go. And MRIs are a pretty blunt instrument for that.
