Salt Lake City, Utah -
(KSL) Ryan Shannon is taking a test, but it's not one that requires a paper and pencil. Instead, her eyes are following a series of projected lasers on the wall.
A saccadometer, a new machine revolutionizing the way doctors analyze possible concussions, measures her rapid eye movement and relays results in real time.
"When something shows up in our visual fields, we should be able to spot it pretty quickly," said Dr. Kenneth Oliver. "With concussions, that just doesn't happen."
Ryan suffered two concussions in less than two months while playing lacrosse for her high school team.
"I couldn't focus on anything," she said. "School was really hard."
