5 Things You Should Know About Traumatic Brain Injuries

Published on

What is a traumatic brain injury?

A traumatic brain injury (TBI) is an injury to the brain caused typically (but not exclusively) by physical trauma. They can negatively impact many brain functions and cause a variety of health issues, including vision issues.

Traumatic brain injuries (TBIs): 5 facts you need to know

  1. Traumatic brain injuries affect approximately 1.7 million Americans each year. About 75% of those injuries are mild TBIs, traumatic brain injuries, or concussions. There are many factors contributing to this high number, including falls, motor vehicle accidents, sports injuries, strokes, and physical violence.
  2. Number one cause of traumatic brain injuries is falls. We usually assume it is automobile accidents or sports-related injuries but the most common cause of traumatic brain injuries is falls.  A CDC report estimates that around 47 percent of traumatic brain injuries occur due to falls, especially among children and the elderly.
  3. In most cases, a concussion does not result in a loss of consciousness. Approximately 10% of concussions will result in a loss of consciousness right after the injury. 
  4. Traumatic brain injuries are significantly more common in women than in men. Part of the reason could be the fact that more women over 15 have experienced some form of physical violence from their partners. Furthermore, women may be more likely to suffer a traumatic brain injury from a fall at home (due to their spending more time at home, on average).
  5. Ninety percent of traumatic brain injuries cause some type of visual problem or deficit.

What vision problems may be caused by traumatic brain injuries?

Symptoms you might experience if you or a loved one have suffered a traumatic brain injury include:

  • Eye strain or pain
  • Headaches
  • Difficulty doing near task for any sustained period of time 
  • Difficulty in the car
  • Difficulty being in crowded environments 
  • Light sensitivity
  • Glare sensitivity
  • Double vision
  • Difficulty with attention and concentration
  • Memory issues
  • Vestibular problems
  • Peripheral vision loss

Schedule an neuro-optometric exam in Chattanooga

The treatment of vision problems caused by traumatic brain injuries is much more well understood today, thanks to specialists like neuro-optometrists specializing in treating these issues.

It is recommended that you schedule a neuro-optometric examination if you are experiencing the symptoms listed above in order to determine if there is an underlying vision problem caused by the traumatic brain injury. If you would like to schedule an eye exam, please call (423) 710 3965.


Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

Thank you!

When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
