“It is a terrible thing to see and yet have no vision”

Helen Keller1880 - 1968

What Does it Mean to See?

What Does it Mean to Have Vision?

Presenter
Presentation Notes

Visual Input/Efficiency

• Ocular Motility• Accommodation• Binocularity

Visual Information Processing/Integration

• Group of visual cognitive skills• Selectively extract visual information from

environment• Integrate visual information with other

sensory systems• Assign meaning/understanding

What is it?

Vestibular Ocular Reflex

• VOR• Stabilize gaze• Balance• Spatial awareness• Navigate space safely

Eileen Before TBI

Q E 2

Dr. Ruth

Visual Pathways

• Primary– Optic nerve Visual Cortex (occipital lobe)

• Via lateral geniculate nucleus (LGN)

Neural Substrates of Vision

Auxiliary

Common Visual SymptomsPost TBI

• Blur• Photophobia• Dry eyes• Diplopia (double vision)/Eyes out of sync• Loss of place when reading• Headaches

Common Vision Related Consequences of TBI

• Dizziness• Mental Confusion• Fatigue

Common Vision Related Consequences Related to Persistent Symptoms

• Anxiety• Depression• Hyper-vigilance• Sleep Disturbances

If vision is not functioning well , it interferes. If functioning well it enhances and stabilizes!

- Dr. John Streff

Remember Vision-Brain Connection

Presenter
Presentation Notes

Pathophysiology of TBI• Closed head injury (vs open): typically causes a more

diffuse or global insultCoup (acceleration) insultContre-coup (deceleration) insultPercussive blast (more with returning veterans)

Results: shearing forces which may lead to:1. Breakage of blood vessels2. Diffuse axonal injury (DAI)

Common Visual Consequences of Acquired Brain Injury

• Blurred Vision• Diplopia• Photophobia• Headache• Visual Field Loss

Ropper & Gorson (2007) NEJM 356: 166-172

•National Hospital Ambulatory Medical Care Survey — United States, 2001–2010 (Emergency Depart Visits)

Neuro-Ophthalmologist: assess visual substrate health

vsNeuro-Optometrist:

restoration of visual function

Presenter
Presentation Notes
*What is the fundamental difference between neuro-OMD and neuro-OD? Neuro-OMD role: diagnose dysfunction of the neurologic substrate of vision per Dr. David Hirsh. Over 40 areas of the brain have vision association, top of pg 6 Suter. This is why neuro-optometry needs to be involved in brain injured patients.

Role of the Neuro-Optometrist• To diagnose and/or treat vision disturbances to

optimize functional vision for use in a patient’s:- activities of daily living (ADL’s) thereby impacting overall quality of life (QOL) - overall rehabilitation (make your job easier )

Visual/Ocular Assessment

• Ocular health• Refractive status

The Neuro-Optometric Evaluation

• Visual Efficiency Assessment• Visual information processing• Visual spatial organization• Visual motor integration• Visual vestibular integration• Posture/gait assessment

Vision Rehabilitation

• Lenses• Prisms• Optometric Vision Therapy• Optometric Phototherapy (Syntonics)• Phototherapy-based Multi-Sensory Training

Presenter
Presentation Notes

Lenses

Prisms

Optometric Vision Therapy

Patient Specific Goals

Establish FeedbackMechanisms

Basic – InvolvingVision and Movement

Complex – InvolvingMultiple Systems

Neuroplasticity at Any Age

Virtual Reality

Optometric Phototherapy

Multi-Sensory Training

• Optometric phototherapy• Vestibular• Auditory• Proprioception

Signs and Symptoms of Visual Dysfunction

• Blur• Eyes out of sync/double vision• Headaches• Confusion• Dizziness• Symptoms made worse in busy visual

environment

Brain Injury Vision Symptom Survey

• Overview• Specificity

Presenter
Presentation Notes
Survey is designed by Hannu Laukkanen at Pacific University College of Optometry 96 % specificity . That is, if a patient gets > or equal to 28 on this survey they have a significant visual problem. Can’t say for certain if the problem is caused by the brain injury.

Professional’s Referral Guide Vision Disturbances and Associated Symptoms Following ABI

Ocular Motility and Vergence Deficits

Limited reading endurance, eye fatigue, HA’s, loss of place, has given up reading

Visual-Vestibular Dysfunction Dizziness, imbalance, motion sensitivity, “shaky” vision, overwhelmed by visually busy environments, “heavy-headedness”

Photophobia Hypersensitive to lights, especially fluorescents; wearing sunglasses indoors

Visual Processing Deficits Concentration difficulties; confusion, unable to multi-task, word retrieval issues

Visual Field Neglect and/or Cut Bumping into doorways, knocking over things; leaning or drifting

Visual-Motor coordination dysfunction

Dropping things, driving difficulties, writing issues
