Visual tracking problems and silent concussions - WHY parents, the public and Optometrists need to know

Therefore, knowing that concussions can be identified 100% of the time with the King-Devick Test, here is another question for parents and the public to ask. Why are we not routinely administering the King-Devick Testing on children, 6 years and older, so that their optometric record establishes baseline in saccadic eye movement?

Dr. Devick is committed to making reliable and objective sideline concussion testing for all athletes accessible and affordable. "The King-Devick Test helps provide a safer sporting environment for youth athletes by accurately screening for concussion," he says. "It's our responsibility as parents, coaches and clinicians to identify concussions in order to remove them from play and allow children the proper time to recover from concussion so they can safely return to learn and play."

Guide to Concussion: Symptoms and How a Vision Test Can Help Diagnose It

Pasted Graphic 1
Neurologists now propose using the King-Devick vision test in the pre-season. This test takes about a minute and involves a timed reading of numbers from an iPad or from index cards. If a suspected concussion occurs during a sporting event, the test is administered, along with the usual balance and cognition tests, at the sidelines. Deviation from the baseline results can be diagnostic for concussion. Imaging and other testing in a hospital may be necessary.

Vision Test Improves Concussion Detection

"I do think this is enough to recommend this vision test be used routinely," Dr. Clugston commented. "This test is less subjective than some of the other tests used currently. An assessment of balance is always very subjective, and cognition tests can be too. But the vision test just involves reading numbers from a screen as fast you can. It is very simple and less easily manipulated by the athlete. But it is best used in combination with the standard tests."

Researchers found the time to complete the test was longer for 79-percent of players who were later found to have a concussion. When combined with other assessments, the sideline test helped diagnose 100-percent of concussions. Experts say using a vision based test on the sidelines may help detect concussions more quickly ... and keep athletes from getting injured further.
