Abstract/Introduction

Introduction: A recent retrospective study shows strong evidence that symptoms of headache, dizziness and anxiety in some patients with traumatic brain injury potentially could be alleviated or even eliminated with specialized eyeglass lenses containing prisms. These lenses resulted in 71.8 percent reduction of symptoms.

Methods: This represents a new approach to the treatment of post-concussive symptoms," says Mark S. Rosner, M.D., adjunct clinical instructor in the Department of Emergency Medicine at the University of Michigan Medical School and Emergency Department staff physician at St. Joseph Mercy Hospital in Ann Arbor. "Vision was known to be affected by TBI, but now it appears that the vision abnormalities caused by the TBI are causing the other post-concussive symptoms.

 


Conclusion/Results

Results: The study suggests that TBI appears to be causing visual image misalignment -- or vertical heterophoria. To correct this misalignment and prevent double vision, the eye muscles are utilized to force the eyes back into proper alignment. This causes the eye muscles to become overworked, strained and fatigued, which accounts for many post-concussive symptoms, including headaches, dizziness, anxiety and neck pain. The use of prismatic eyeglass lenses to realign the images and reduce or eliminate eye muscle overwork led to a 71.8 percent reduction of patient's symptoms.

TBI affects 15 to 20 percent of our servicemen and women returning from Iraq and Afghanistan -- caused mostly by explosions -- and approximately 2 million people per year in the U.S. -- caused mostly by falls, auto accidents and sports injuries. Approximately 10 to 25 percent of patients with TBI still have significant post-concussive symptoms one year after their injury.

Conclusion: Treatment involves a multifaceted approach, including physical therapy, occupational therapy and multiple medications, and can take years to complete," says Jennifer E. Doble, M.D., a physiatrist at St. Joseph Mercy Hospital, Ann Arbor. "Prismatic lens treatment seems to allow the other therapies to be effective more quickly. And as a result, patients get better quicker, reducing the time and cost of caring for this patient population."

The first patient with TBI was recognized as having vertical heterophoria in 2005 by two of the study co-authors -- Doble, a TBI rehabilitation specialist -- and Debby L. Feinberg, O.D., an optometrist at Vision Specialists of Birmingham, Birmingham, Mich. The overlap of TBI and vertical heterophoria symptoms was significant: headaches, neck ache, upper back pain, dizziness, nausea, anxiety and reading difficulties. To date, no single unifying cause of TBI symptoms had been identified.


Testimonials


  • 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.

  • 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!
