✨ Acquired Brain Injury

What is Acquired Brain Injury?

Acquired brain injury (ABI) is an umbrella term for damage to the brain that occurs after birth and excludes congenital disorders and birth trauma. Typically this damage is sudden, non-progressive, non-degenerative, and leads to abnormalities in neurological processing. These neurological changes can adversely affect the way a person functions in their activities of daily living, i.e., thought process, emotional behavior, speech ability, and physical changes such as impaired motor function and sensorimotor abilities, and often times, vision!

Types of Acquired Brain Injury

ABI can be from an external traumatic injury (where the brain encountered physical trauma from such incidents as a motor vehicle or bicycle accident, a fall, an assault, contact sports, or neuro-surgery, etc.) or can be from an internal cause (a stroke, an aneurysm, a brain tumor, a viral infection or inflammation such as meningitis, a vestibular dysfunction such as Ménière's disease, or any post-surgical complications leading to an anoxic or hypoxic event in the brain).

Visual Problems Associated with Brain Injury

  • Blurred vision at distance viewing
  • Blurred vision at near viewing
  • Slow shift of focus from near-to-far or far-to-near
  • Double vision
  • Pulling or tugging sensation around eyes
  • Unable to sustain near work or reading for periods of time
  • Difficulty copying or taking notes
  • Loss of place while reading
  • Eyes get tired while reading
  • Headaches (general and while reading)
  • Covering/closing one eye
  • Easily distracted when reading
  • Decreased attention span
  • Reduced concentration ability
  • Difficulty remembering what has been read
  • Loss of balance
  • Postural shifts/veering off when walking
  • Face/head turn or head tilt
  • Bothered by movement in the environment and/or crowded places
  • Light sensitivity
  • Dizziness
  • A sensation of the floor, ceiling, or walls tilting
  • A sensation of the room spinning
  • A sensation of not feeling grounded
  • Difficulty with memory and attention

🧭 Vision Evaluation & Management

Patients should obtain a vision evaluation (sometimes called a neuro-optometric vision evaluation) from an optometrist who has specific interest and/or training in diagnosing and managing problems with binocular vision and provides vision rehabilitation in the form of special glasses (that include a specific prescription, prisms, tints, and/or coatings) or in the form of in-office or out-of-office visual rehabilitation. When scheduling an eye examination, ask if the optometrist provides evaluation services for binocular vision problems and neuro-optometric rehabilitation.


Generally, early intervention is most beneficial, but it is never too late to seek rehabilitation after a brain injury.


There are symptoms surveys you can complete to see if you have visual problems that may benefit from neuro-optometric vision rehabilitation.


Symptom Surveys:

Neuro-Optometric Vision Evaluation includes:

  • Case history & questionnaires
  • Refractive analysis & ocular health
  • Eye movements, alignment, accommodation, vergence, sensory fusion
  • Visual perception testing

Treatment Options

  • Lenses, prisms, tints/coatings
  • Selective occlusion
  • Neuro-Optometric Rehabilitation procedures

Optometrist – Neuro-Optometric Rehabilitation

Evaluation and management of binocular vision and post-trauma vision syndrome.

Physiatrist

A medical doctor who specializes in physical medicine and rehabilitation, physiatrists work in rehabilitation hospitals and private clinics. Part of their role is to make therapy recommendations for patients after an acquired brain injury. As neuro-optometrists we often get referrals from Physiatrists and keep them updated on their patient's visual rehabilitation process.

Neurologist

A medical doctor who diagnoses and treats neurological conditions including acquired brain injury. Neurologists, like physiatrists often make therapy recommendations as well and refer patients to neuro-optometrists. We also correspond with neurologists to keep them abreast of their patient's progress in visual rehabilitation.

Neuropsychologist

Provides helpful information about how a brain injury affects a person's behavior, mood and thinking skills. They may detect slowed visual processing and recommend a referral to a neuro-optometrist. We may use the information in their reports to help guide our treatment recommendations. Another note: oftentimes acquired brain injury patients cannot complete the full neuropsychology evaluation because their visual symptoms are too severe. The neuropsychologist may complete an abbreviated version and have you start visual rehabilitation, and then complete the rest of the assessment when your visual skills have improved.

Physical Therapists

A physical therapist may help with muscle weakness, pain, spasticity, and balance difficulties after an acquired brain injury.

Vestibular Therapist

A vestibular therapist is a physical therapist that has special training in dizziness, balance, and coordination. Because of the intimate relationship between vision and the vestibular system, we often communicate with our patient's vestibular therapist to allow for the best outcome in patients who have both visual and balance difficulties after an acquired brain injury.

Occupational Therapist

Helps patients with acquired brain injury achieve skills for instrumental activities of daily living (IADLS) such as dressing, cooking meals, cleaning. In many hospital settings they also assess and treat visual difficulties. It is important to note that a neuro-optometric evaluation is still recommended even if you have seen an OT for a visual assessment. They are able to assess vision up to their scope of practice which is more limited compared to a neuro-optometrist scope of practice. We find the OTs reports to be helpful to understand where you started in your recovery and to see what activities the OTs have done to help you with your visual tasks.

Cognitive Therapist

This can be an occupational therapist who is working on functional cognition, or a speech and language pathologist who can help with executive function, memory, planning and communication. As neuro-optometrists, we collaborate with cognitive therapists to help improve patients' visual skills so that they can better participate in cognitive therapy.

Speech and Language Pathologist

In more severe acquired brain injuries the SLP will work on speech and communication, and in mild acquired brain injuries they mostly work on cognition which includes executive function, working memory, planning, and problem solving. Because visual aids are a component of their therapies, SLPs benefit from understanding the patient's visual difficulties and limitations.

πŸ’‘ Tips for Managing Visual Symptoms

Energy Management

Break tasks into smaller increments, take frequent breaks, gradually increase tolerance.

Managing Light Sensitivity

Natural light is best. Use wraparound sunglasses outdoors. Avoid full-time indoor sunglasses to prevent worsening sensitivity.

Reduce Visual Overload

Declutter essential items like keys, phone, and glasses. Create organized spaces.

Keep Eyes Moisturized

Use lubricating eye drops for dry eyes, tailored to your type of dryness.
