Aquired Brain Injury

Acquired brain injury, which includes concussion, traumatic brain injury, stroke and neuro-degenerative conditions, can have several effects on the visual system. These conditions include:

  • Accommodative dysfunction (impaired eye focusing)

  • Binocular vision dysfunction (impaired eye teaming, including convergence palsy)

  • Dry eye syndrome

  • Oculomotor dysfunction (impaired eye movement or tracking)

  • Pupil anomalies

  • Ptosis (sagging or drooping eye lid)

  • Strabismus (eye turn, wandering eye, crossed eye)

  • Visual field loss (peripheral vision or 'side vision' loss)

  • Visual attentional neglect (inability to attend to information on one side of the body)

  • Visual perceptual deficits or visual agnosia – including visual-spatial deficits

  • Prolonged visual processing speed

  • Impaired visual working memory

 

Post-trauma vision changes are extremely common. In fact, studies have shown that more than 50% of patients experience double vision (although many fail to report or recognize it during the recovery phase). Changes in vision can be difficult for the patient to describe, or they may not be discussed in the acute phase of care. When a patient suffers a traumatic brain injury, stroke, or other neurological event, the priority of their doctor is to stabilize the patient. Vision is often a topic that is left out of the conversation. Also, many vision symptoms do not surface immediately after the incident or may not become problematic until the person enters into rehabilitation or attempts to return to work.

 

Symptoms due to post-trauma vision conditions include:

  • Asthenopia (eyes feel strained, uncomfortable, or sore)

  • Attention or concentration difficulties

  • Balance difficulties

  • Blurred or fluctuating vision

  • Diplopia (double vision)

  • Dizziness or nausea

  • Fatigues easily (especially with near work, reading, computer)

  • Glare sensitivity

  • Headaches

  • Motion sickness or difficulties with mobility

  • Bumps into objects or walls

  • Difficulties moving through crowded spaces

  • Poor depth perception or 3D vision

  • Abnormal posture (head posture, leans to one side, forward or backwards)

  • Photophobia (light sensitivity)

  • Difficulties with reading fluency or comprehension

 

It is difficult to list every symptom that a patient may experience due to visual changes following a neurological event. It is important that every patient who suffers a form of acquired brain injury (concussion, traumatic brain injury, stroke, neuro-degenerative condition, etc) receive a Neuro-Optometric Assessment with a Residency-Trained Neuro-Optometrist. The majority of eye doctors (optometrists and ophthalmologists) are not trained in the area of neuro-optometry and do not perform the necessary testing to adequately diagnose post-trauma vision changes. Without a comprehensive Neuro-Optometric Assessment, diagnoses may be missed and the opportunity for treatment and improvement may be lost.

Traumatic Brain Injury (TBI) is a term used within the medical community to describe an injury to the brain which is not hereditary, congenital or degenerative. Traumatic Brain Injury can be result from a blow to the head, whiplash, seizure disorders, tumors, stroke, toxic exposure, or infectious diseases to name a few. The incidence of prevalence of brain injury outnumbers breast cancer, spinal cord injury, multiple sclerosis and HIV/AIDs combined.   ... Read More
Many people have heard of vision therapy, but don't know a lot about it. As with any type of therapy, the effectiveness of the program is dependent upon several factors. It is advisable to ask questions and do your homework. Vision therapy programs vary greatly from provider to provider. ... Read More
  Everyday in our schools students are presented with information that they are required to look at, interpret, and process that information. For years it was believed that the eyes had nothing to do with learning. That is definitely not the case. Did you know it is estimated that 80% of what we learn is through visual information?     ...

  Convergence Insufficiency (CI) is a common eye-teaming problem which occurs when the eyes are unable to maintain the ocular posture necessary for reading or near tasks. Convergence Insufficiency results from misalignment of the eyes when focusing on up close, such as when reading. The eyes have a strong tendency to drift outward when reading or doing close up work. The exact cause is unknown.    ... Read More

  The human brain measures time continuously, and has developed three general classes of timing systems: circadian, interval, and millisecond timing. Neuroscientists believe that we have distinct neural systems for processing these different types of time. Poor timing or synchronization between the three major brain networks has been implicated in several conditions.   ... Read More
