What can really be done to enable a dyslexic adult? Today’s report on Sandra Fox

Sandra is a professional supporting disabled students. We decided last year to see just what can be done to enable a severely dyslexic adult.

Last September we had a preliminary meeting which showed that there was a correctible ophthalmic component to her difficulties. This was despite the prescription she already had. It was a clear issue which showed up with discussion, minimal testing and from use of the binocular eye tracker.

In September we calculated an optimal computer background setting and decided that we would arrange for Sandra to be seen by an ophthalmologist I have been collaborating with.

Today 6 months later Sandra saw my colleague and we had confirmation about her condition and calculation of what prescription was needed.

I then retested her for optimal computer settings.

Below are some details about the outcomes. We wait excited to find out what happens when we finally have the correct glasses for her. 

Watch this space.

There is a video on U-Tube showing the original consultation.
There will be  detailed report coming soon


The graph below shows Sandra’s reading on a default computer screen on September 14th 2012.
37.575 seconds for 85 words 494 characters 120 fixations.

4.11 characters per fixation

313 milliseconds per fixation
136 words per minute

The graph below shows Sandra’s reading using her optimal conditions but without her optimal glasses on February 20th 2013.
12.84 seconds for 88 words.  515 characters. 50 fixations

10.03 characters per fixation.
257 milliseconds per fixation

411 words per minute

What will happen when she has her perfect pair of glasses?

Please keep in mind my comments on crowding, visual attentions span and perceptual span in the last blog.

More details to come.
