The Impact of Concussion on Vision…the latest video from VisionHelp

The Impact of Concussion on Vision is the latest installment  from the VisionHelp Group that brings together leading experts in vision development and rehabilitation along with the personal side of this issue because a young woman, Abby, tells her story about life after a concussion.

For Abby it was just another day riding in the car when suddenly and without warning she was T-boned. Her car flipped 3 times before she came to a stop. In many ways she was fortunate because she survived the crash. The doctors at the hospital told her to go home and get some rest. But, from that point on her world had changed. Her vision was no longer the same. She was dizzy and the room moved just as if she had gotten off a boat. She couldn’t work like she used to, it was very frustrating and it wasn’t simply going away with rest and time… until she sought vision rehabilitation.

Take a moment to watch this short video and learn how concussions can have a significant impact on a person’s vision and yet, with vision rehabilitation there is help.

Lunch and Learn…Wow Vision Therapy and Children’s Therapy Center in South Bend

100_6553100_6552Yesterday Dr. Fortenbacher, along with Wow Vision Therapy’s Clinic Director, Dr. Lindsey Stull, and resident,  Dr. Tuan Tran presented to the staff at the Children’s Therapy Center at Memorial Children’s Hospital in South Bend. The program was part of the new “Lunch and Learn” educational series that provides a much more personal and interactive experience for the OTs, PTs and SLPs at the Center.

100_6557Dr. Fortenbacher (and team) were able to present, over the course of the lunch hour, 3 recent or current patients in treatment and engage in a collaborative Q&A discussion. Written and video presentations helped to show how these children obtain the best outcomes in their overall progress through office-based optometric vision therapy and a multidisciplinary approach provided by the team at the Children’s Therapy Center.

100_6550During the discussion there were some who asked about how to obtain more information about developmental vision and vision rehabilitation. For those who want to find out more detailed information about these topics the following was recommended:

Oculomotor Dysfunction Following an Acquired Brain Injury

The term acquired brain injury (ABI) refers to traumatic brain injuries (TBI) and cerebral vascular accidents (CVA), or stroke.  Each year an estimated 8 million people will suffer a traumatic brain injury and 500,000 will suffer a CVA.  According to a study conducted through the State University of New York State College of Optometry and the Raymond J. Greenwald Rehabilitation Center in New York, the majority of all ABI patients will develop some degree of an oculomotor dysfunction.

The five areas of oculomotor dysfunction researched in this study were accommodation, version, vergence, strabismus and cranial nerve palsy.  Although all ABIs are unique to the individual, certain oculomotor dysfunctions were found to be more prevalent given the type of ABI.  The following statistics represent the trends found through this particular study.

  • More than 40% of the TBI patients demonstrated an accommodative dysfunction while the amount of CVA patients with this deficit was only 12.5%.
  • Convergence insufficiency was found to be the most frequent vergence dysfunction in both the TBI and CVA patients.
  • Nystagmus, a version oculomotor dysfunction, was 30 times more prevalent in the CVA subgroup in comparison to the TBI patients.
  • Approximately one fourth of TBI patients and 37% of CVA patients had acquired some form of strabismus.
  • Ten percent of CVA patients had a cranial nerve palsy, primarily 3rd nerve palsies, while 7% of TBI patients had a cranial nerve palsy, primarily 3rd and 4th nerve palsies.

The study indicates that 90% of the TBI patients and 86.7% of the CVA patients manifest some form of oculomotor dysfunction.  Based on these significant statistics, it’s imperative that these patients receive a comprehensive eye examination to adequately address any underlying binocular vision problem that may exist.  Each ABI case must be addressed on an individual basis, however there are certain trends that one should be aware of when determining the appropriate treatment plan for these patients.
