Overview of Neurological Vision Rehabilitation System

  1. 1. 1<br />Assessment and Training for people with Neurological Vision Deficits<br />NVT: Developed by Clinicians, for Clinicians<br />
  2. 2. Acquired Brain Injury<br /><ul><li>Acquired Brain Injury (ABI) is damage to the brain by a variety of causes; hypoxia, infection, tumour, substance abuse, degenerative neurological diseases, strokes or head trauma (TBI).
  3. 3. Traumatic Brain Injury (TBI) implies trauma to the head and brain caused by an external force.
  4. 4. ABI can cause physical, cognitive, psychosocial and sensory impairments which may lead to restrictions in various areas of a person’s life and lifestyle. </li></li></ul><li>2.2 Million People in the US Acquired Brain Injury<br />Every Year<br />1.5 million Traumatic Brain Injury: every 21 seconds<br />700,000 will have a Stroke: one every 45 seconds<br />Stroke is the number 3 killer and leading cause of severe, long-term disability<br />
  5. 5. 4<br /> Neurological Vision Impairment<br /><ul><li>Neurological Vision Impairment occurs in 30 – 35% of all people who suffer a </li></ul>Stroke or Traumatic Brain Injury.<br />“50% of the patients in a head trauma rehabilitation centre show visual system disorders not assessed before, although most of the patients were chronic and had been treated in other hospitals previously.” (Gianutsos)<br />
  6. 6. Neurological Vision Deficits<br />
  7. 7. 6<br />Vision Therapy<br /><ul><li>Neurological Vision Impairment will affect all aspects of a persons daily life.
  8. 8. It would be standard care to receive:
  9. 9. Physiotherapy– for improvement in loss of body functions or reduced movement.
  10. 10. Occupational Therapy – to increase upper body strength and activities of daily living.
  11. 11. Speech Therapy - swallowing, word pronunciation, comprehension etc
  12. 12. In many instances there is no minimum clinical standard of care that covers Vision Screening for people with ABI
  13. 13. Therefore vision deficits can go undiagnosed and untreated.</li></li></ul><li>7<br />Assessment of Visual Function<br />
  14. 14. 8<br />NVT Protocol Functional Vision Assessment<br />
  15. 15. 9<br />Visual Perceptual Deficits<br />Homonymous Hemianopiais the most common cause of visual field loss, quadrantanopia, relative field loss.<br /><ul><li>Visual Neglect/Visual Inattention - patients can be unaware of the extent of vision loss – causes difficulty with ALL activities of daily living (reading, eating, dressing, mobility in busy or unfamiliar areas).
  16. 16. Visual processing speed
  17. 17. Visual Memory
  18. 18. Visual Spatial deficits</li></li></ul><li>10<br />NVT Standardized Scanning Assessment<br />
  19. 19. 11<br />Case Study - Angela<br /><ul><li>Motor Vehicle Accident TBI:
  20. 20. Damage to:</li></ul>frontal lobe, <br />bi-temporal, <br />bi-parietal and <br />occipital craniotomy<br /><ul><li>Left Homonymous </li></ul>Quadrantanopia<br /><ul><li>Left Neglect
  21. 21. Visuo-spatial deficits
  22. 22. Visual processing deficits
