Following a concussion, vision symptoms of blur, visual fatigue, inability to tolerate busy moving environments, photophobia, headaches, loss of comprehension, difficulty with balance, are often experienced. Persons with these symptoms frequently are evaluated and have 20/20 acuity, no loss of visual field, ocular paresis and have normal eye health. This Symposia will review the compromise of the neurology that causes visual dysfunction. Research will be presented about compromise of visual processing that causes symptoms and presents specific characteristics such as convergence insufficiency, oculomotor dysfunction,, accommodative insufficiency to name several. Research will be reviewed and demonstrations will be provided to show how compromise of visual processing can interfere with visual function and produce binocular, characteristics and difficulty with balance. Evaluation methods including visual evoked potentials and gait balance analysis in addition to screen for binocular imbalance will be provided.
1.To develop a differential understanding of the neurology of the eye and brain pathways that can be compromised by concussion to produce visual processing dysfunction, accommodative spasms , occipital neuralgia and associated symptoms and characteristics.
2. To differentiate between focal and ambient vision, the bi-modal visual process, and how these processes are affected neurologically and functionally by a trauma.
3. To define the key characteristics of post-trauma vision syndrome/visual midline shift syndrome and how trauma can affect the neurology as well as impact the process of vision affecting balance, posture, spatial orientation and the use of vision for attention and concentration sucne as during reading, etc.
4. To explain how the neurology of the visual process can be influenced by asymmetrical and yoked prisms to affect posture, movement, balance, attention, concentration, etc. thereby affecting rehabilitative outcome in conjunctin with physical, occupational, speech, recreational therapies. t
5. To describe the affect of compromise of visual processing following a concussion to produce visual symptoms and characteristics of a visual processing dysfunction.
