I am a reading specialist who focuses on helping students with dyslexia. Earlier this week my nephew, who’s dyslexic, was diagnosed with convergence insufficiency and saccadic dysfunction. I’m not familiar with this. My understanding is that it impacts his ability to cross his midline. Specifically, I’m curious how it can/will impact his sound/symbol knowledge, and if there is anything I can do to help him learn his sound/symbol associations and early decoding skills.

Dr. Pierson's Response: 

You ask a good question -- vision therapy will NOT help your nephew learn sound/symbol associations. As you are aware, dyslexia is a language-based learning disorder. It is not a problem with vision. Yes, the eyes have to work, but the core deficit in dyslexia is in phonological processing. Here are two pieces (piece 1) that I and my colleague Dr. Lauren Katz wrote about vision therapy and dyslexia (piece 2).

As you can see from these articles, vision therapy is not the answer to teaching a child to read. The intervention approach is called structured literacy. I would recommend a good comprehensive assessment from someone who knows how to assess and diagnose dyslexia to get at his profile of strengths and weaknesses.
