Neuro-Optometry

Neuro-Optometry is a sub-specialty of optometry involving assessing and treating patients with brain injuries from a variety of causes:

• traumatic e.g. concussion or more severe traumatic injury, 
• acquired e.g. stroke, brain tumour
• neurological disease e.g. Parkinsons, MS

The neuro-optometric assessment from our Behavioural Optometrist, Sarah Lang, involves the normal parts of a traditional eye examination like eye health checks, measurement of visual acuity on the letter chart, checking peripheral vision and glasses prescription. However, it is more comprehensive and takes a detailed history of any brain injuries and the subsequent difficulties, looks at eye movements, the co-ordination of the two eyes together (binocular vision) and the focussing of the eyes as these are commonly affected in a brain injury. It may also involve an investigation into balance, which involves three sensory systems – vestibular, proprioception and vision.

Common symptoms from a brain injury or neurological disease:

• Blurred vision – especially for close work
• Double vision
• Difficulty moving the eyes fully in all directions
• Light sensitivity or photophobia
• Visual Motion Sensitivity – difficulty with movement in your peripheral vision e.g. when walking down a supermarket aisle
• Dizziness or nausea – especially with head movement
• Dry eye
• Difficulty processing visual information – especially simultaneously with other information

Treatment may include:

• Glasses – which may incorporate prism or a custom coloured filter 
• Vision therapy – a programme of activities to work on areas of weakness or to integrate other sensory systems with vision e.g. vestibular (balance) or improve brain processing of visual information to make it more automatic
• Further testing or referral
• Treatment for dry eye
• Explanation of the problem and how to compensate for any deficits
