Traumatic Brain Injury

Vision is our dominant sense

More than just sight is measured in terms of visual acuity, vision is the process of deriving meaning from what is seen. It is a complex, learned and developed set of functions that involve a multitude of skills. Research estimates that eighty to eighty five percent of our perception, learning, cognition and activities are mediated through vision.

TBIVisionSymptoms

The ultimate purpose of the visual process is to arrive at an appropriate motor, and/or cognitive response.

There is an extremely high incidence (greater than 50%) of visual and visual-cognitive disorders in neurologically impaired patients (traumatic brain injury, cerebral vascular accidents, multiple sclerosis etc.) Rosalind Gianutsos, Ph.D.

The process of vision can be broken down into three categories:

1. Visual Acuity and Visual Field

2. Visual Motor Abilities

3. Visual Perception.

Visual Acuity & Visual Field

Acuity:

This refers to clarity of sight. It is commonly measured using the Snellen chart.

Field:

This is the complete central and peripheral range, or paNORAma of vision. Various neurologic conditions, such as stroke, cause characteristic losses of the visual field, for example hemianopsia.

Other areas affected by traumatic brain injury include:

  • Alignment
  • Fixation
  • Visual Closure
  • Spatial Relationships
  • Figure-Ground Discrimination

Vision Therapy and Traumatic Brain Injury
by Eric Singman MD PhD

Vision difficulties after traumatic brain injury (TBI) are common and often difficult to
recognize. I have had an opportunity to formally review efforts concerning both the assessment of visual dysfunction as well as therapies available for these concerns. Although there are relatively few studies defining the best approach to rehabilitating patients suffering TBI, current evidence supports a multidisciplinary program. As with any large team endeavor, coordination of responsibilities is necessary for success. Among the critical members of this team, there should be vision specialists dedicated to working with patients who demonstrate deficiencies in eye teaming, loss of visual acuity and/or visual field as well as uncoupling of “visuospatial awareness”. For the most part, the optometric and neuropsychological communities have embraced visual rehabilitation efforts; notably, these providers have documented successes in helping brain injury patients improve their quality of life.

SYNTONICS Healing

Syntonic - or Optometric - Phototherapy may be a vital feature of your treatment plan. In his article, "The Theory and Practice of Syntonic Phototherapy: A Review", Dr. Larry Wallace illustrates the benefits of Syntonic Phototherapy when prescribed as a supplement to traditional treatments for Traumatic Brain Injury. "The application of colored light for healing dates back to the earliest times of recorded history, including Egyptian and Mayan civilizations," writes Dr. Wallace. "The vascular system serves as a major carrier of light sensitive chemicals. The classic example is the use of blue light to treat neonatal jaundice. Bilirubin is a yellow chemical that accumulates in the tissues, and that readily absorbs light at 450 nanometers. It is broken down and eliminated after exposure to blue light. The blood contains photo acceptor molecules that absorb visible light radiation and then regulate various biochemical activities." When applied correctly, energy treatments like Syntonic Phototherapy - which can enhance everything from binocularity and accommodative facility, to visual discrimination and information processing - may mark a new epoch in the long-term treatment of TBIs.

Both TBIs and strokes affect the brain, the Vision Information Processing System (VIPS) is also affected. This is the "wiring" of the visual system as it relates to visual input. in most cases, the Visual System can be reprogramed with Vision Therapy.
