Often an individual’s

visual ability

is taken for granted or misunderstood after injury. 

 

Degenerative diseases with associated visual limitations

can be hard to assess, predict and plan.

 

If you are a rehab professional struggling to connect

a client’s visual challenges to their workplace or a specific job to a client,

 

Visual Demands Analysis

can help...

How does a VDA fit with my practice?

As a rehab professional, you already offer services such as Job Analysis, Return-to-Work Programs, Functional Abilities Evaluations, Transferable Skill Analysis etc.  Think of a Visual Demands Analysis (VDA) as another valuable service you can offer.   VDA's can be incorporated into your practice regardless of your knowledge about eyes or vision.  A VDA creates more value for your organization through more successful outcomes.  Let us do all of the heavy lifting.

  • Feb 2 - 2016    Finally seeing more-and-more awareness around Post Traumatic Vision Syndrome (PTVS) > an under-diagnosed and under-treated vision system condition associated with concussion... Great link to PTVS info video on >  CTV news.  You do not need to have injury to the eyes to have vision issues.  Dr.j   www.visualdemands.com 

  • July 30 - 15  |  There are different ways to look at the visual system.  For a rehab professional, it would probably be most useful to view vision as having two distinct systems... [1] the focal system i.e. the eyeball (which focuses light and needs to be healthy to function properly) and the visual cortex (sight center of brain) and  [2] the ambient system responsible for spacial awareness - visual information going to non-sight centers of brain.  It is possible to have eyeball injuries with MVA's and workplace accidents but those injuries are likely well documented and managed by eye care specialists.  As a rehab specialist, you will likely by dealing with the much less well defined, less clear-cut symptoms and sequelea related to the ambient system.  Dizziness, headaches and blurry vision can all come from injury to the ambient system.

    The input (light energy) received through the eye is split when it hits the brain.  Some of the visual information (nerve impulses) go to the visual cortex for processing as sight however much of the visual information is plugged into proprioceptive and balance systems.  If the input traveling these non-sight centers of the brain does not match the historic/learned reference... confusion and consussive-type symptoms of headache and visual strain occur.

    An occupational vision or vision therapy specialist can help with glasses and/or visual therapy to coordinate these systems and minimize symptoms.

  • June 25 - 15  |  Perhaps in your experience as a rehab professional you have run across an Optometrist's or Ophthalmologist's recommendation for vision therapy.   Why would this 'extra' treatment and expense be required?   Vision therapy/training deals with issues of the visual system beyond what glasses can correct.  When I am assessing someone with post-injury visual complaints... Step one is to make sure that the eyes are healthy and were not injured.  Step two is to fully correct the focus of the eyes with appropriate lenses.  Step three is to assess how the eyes work together  i.e. tracking, coordination, convergence etc..  Problems with how-the-eyes-work-together (binocular vision) can confound your clients' progress through headaches, vertigo, poor concentration, reading errors.  Some binocular vision issues can be improved with lenses but many respond well to training the muscles that control the eyes - similar to physical therapy for the eyes.  Training courses can be 3-20 weeks long and typically have home training for patients to complete.  Most Optometrists do basic vision training but in every community there will be those that specialize in this field.   dr.j  Studioeyecare.com
