Over 60,000 people in North Carolina will suffer from a traumatic brain injury this year:
20-40% will experience vision loss
Common Vision Conditions that Arise From TBI/Concussions
Binocular Vision Issues/Eye Teaming:
Binocular vision refers to the ability of the brain to use both eyes simultaneously to focus on one object. This task is used to create depth perception and a wider field of view among other important visual tasks. The most common Binocular issue is convergence insufficiency which affects reading, balance and spatial perception.
Accommodative Eye Focusing:
Accommodative focusing problems lead to a variety of symptoms such as blurry vision, eye strain, difficulty focusing, and headaches.
Eye Movement and Tracking/Oculomotor Dysfunction:
Some experts estimate that up to 90% of people with traumatic brain injury experience some form of oculomotor dysfunction. This visual skill is essential for reading, using the computer, and other skills.

Vision Therapy For Traumatic Brain Injury
A brain injury or the resulting condition such as the ones listed below can result in serious vision problems, which can have a devastating effect on one's ability to complete basic day-to-day tasks. The damage can also be cumulative over time. Multiple concussions, even minor ones, can result in serious long-term complications.
Contrary to what you might think, it is the brain, and not the eyes, that is the key to seeing well. Your vision is really the sum total of how your brain receives visual information and then interprets and processes that information to permit you to see. The accuracy of that process depends on a healthy brain correctly going about this processing.
There are many different types of brain injuries that affect vision including: Traumatic Brain Injury, Mild Acquired Brain Injury, Hemianopsia or Hemianopia, Mild Closed Head Injury, Post-Concussion or Post-Concussive Syndrome, Cervical Trauma Syndrome, Stroke, Cerebral Palsy, Cerebral Vascular Accident, Post Traumatic Vision Syndrome, Stroke.
Brain Injuries such as whiplash and concussions can cause serious vision issues that make it difficult to do many of the tasks we take for granted.
Common vision issues from TBI are:
- Blurry vision
- Double vision
- A loss of side vision (peripheral vision)
- Pain or achy eyes
- Difficulty with spatial assessment (depth perception, sports, balance)
Our Charlotte vision therapist that focuses on traumatic acquired brain injury will assess how the brain processes visual information prior to developing a rehabilitation program for the patient. The focus of vision therapy for an acquired brain injury is to treat the visual symptoms which will then allow the patient to pursue other forms of rehabilitation more effectively.
Any trauma to the head can cause a brain injury that leads to some kind of vision loss. Car accidents with whiplash, sports injuries, strokes, brain tumors, infections or inflammation of the brain are some of the more common causes of vision loss from acquired brain injuries.
Meet our Charlotte Vision Therapy eye doctor, Dr. Laura Ashe.
Dr. Laura Ashe attended the Southern College of Optometry where she was awarded the College of Optometrists in Vision Development Vision Therapy Award. After graduating she completed a residency in Pediatrics and Vision Therapy.
Dr Ashe’s passion for helping people, has driven her to complete of over 100 hours of continuing education in the areas of Vision Therapy and Pediatric Optometry.
“My favorite part about being an optometrist is helping people with their most precious sense: sight. What allows me to do this is appropriately diagnosing, managing, treating and educating my patients, and understanding that patients are not a set of eyes, but real people!”
Prior to joining Complete Eye Care, Dr. Ashe served as a primary care optometrist as well as a Consulting Faculty at Southern College of Optometry in Pediatrics and Vision Therapy Dr. Ashe’s goal is to ensure efficient visual development in the pediatric population. She is a member of the College of Optometrists in Vision Development (COVD), The American Optometric Association, and the North Carolina Optometric Association.
There are innumerable potential causes of brain injuries that can result in vision problems.
Our vision therapy practice in Charlotte, North Carolina specializes in Neuro-Optometric Rehabilitation ― a specific Vision Therapy program for those who have suffered a brain injury. Using series of custom and personalized exercises, the brain can be retrained to accurately receive, process, and interpret visual signals again. Research has shown that recovery from vision problems is essential to recovery from any brain injury.
Problems such as these can drastically affect day to day functioning even at the most basic levels. It’s only once such vision problems are addressed that the victim of a brain injury can get the most out of other treatments such as physical, occupational, and cognitive therapies.
This includes:
- Diplopia (double-vision)
- Tracking issues
- Maintaining physical eye focus
- Difficulty staying mentally focused
- Strabismus (eye turns)
- Binocular Vision Dysfunctions (the ability to coordinate the two eyes to work together)
- Abnormal posture
- Head tilts or turns
- Bumping into objects
- Closing or covering one eye
- Balance and coordination problems
- Reduced ability to sustain attention on visual tasks
- Poor depth perception
- Confusion related to visual tasks
- Reduced ability to accurately
- Difficulty reading localize objects
- Reduced visual acuity at far (perceptual accuracy at a distance)
- Reduced visual acuity at near (perceptual accuracy up close for reading and other tasks)
- Accommodative Disorders (problems with focusing the eyes)
- Difficulties in visual perception (are objects where I think they are?)
- Visual Field loss (loss of vision in one or more areas)
- Deficits in visual motor (eye movement problems)
- Ocular Motility Disorders Integration (problems coordinating our eyes with our bodies )
- Problems with accurate visual information processing
Problems such as these can drastically affect day to day functioning even at the most basic levels. It’s only once such vision problems are addressed that the victim of a brain injury can get the most out of other treatments such as physical, occupational, and cognitive therapies.

The vision problems highlighted above can be broken down into three main areas of vision problems. Your Developmental Optometrist utilizing Vision Therapy techniques can help with each of these Vision Loss problems:

Visual Field Loss
Visual field loss refers to a condition where the patient loses vision in a portion of their field of vision. This can quite literally mean that the patient is blind or impaired in half of the field of vision. This can be dangerous as it often results in walking into objects, falling, and being hit by approaching objects and people.
Treating Visual Field Loss
With Vision Therapy, the patient will undergo visual rehabilitation exercises which teach the brain to relearn how to effectively scan and focus on the impacted fields of vision where the vision loss occurs. This can be a long process, requiring patience and force of will. However, with time and temerity, Vision Therapy is highly effective at correcting and regaining a lost field of vision.
Prism Lenses For Visual (Peripheral) Field Loss
Special visual field awareness prism lenses are used in treating peripheral field loss. As the patient scans into the prism, the optics are shifted so as to perceptually gain about 15 to 20 degrees of visual field recognition. Looking into these prisms, however, results in double-vision (diplopia), so active scanning is done in brief spurts. The lenses are used to sense if there is something in the peripheral vision that needs to be paid attention to. Once spotted, the patient turns their head to view it in detail with their intact central vision.

Double Vision & Brain Injury
Diplopia, or, “double-vision” is a very common result of a brain injury. Prisms, special lenses, and Vision Therapy can be used to help the patient achieve fusion (alignment of the eyes) and alleviate the diplopia. If and when these means are not employed, the patient may be able to adapt by suppressing the vision of one eye to eliminate the diplopia. If lenses, prisms, and/or a course of Vision Therapy are not successfully undertaken and applied, the result is often what’s called intractable diplopia.
In this population of patients, patching has frequently been used to eliminate the diplopia. Although patching is effective in eliminating diplopia it causes the patient to become monocular. Monocular vision, as opposed to binocular vision, will affect the individual primarily in two ways; absence of stereopsis and reduction of the peripheral field of vision. These limitations will directly cause problems in eye-hand coordination, depth judgments, orientation, balance, mobility, and activities of daily living such as playing sports, driving, climbing stairs, crossing the street, threading a needle etc.
Vision Therapy, combined with the appropriate lenses and prism use, is the most effective means of treating the diplopia while retaining and improving the visual functions necessary for daily life.

Visual Balance Disorders
Visual balance disorders are conditions where the patient feels dizzy or unsteady. Often, it feels as if the sufferer or the world is spinning or moving even while lying down. Visual balance disorders can be caused by viruses, ear infections, and problems with visual processing. It’s also a frequent problem with patients who have suffered a brain injury. Lenses, prisms, and visual rehabilitation activities through Vision Therapy are highly effective at treating visual balance conditions.
