So today, let’s talk science.  I recently had a conversation with a well-known pediatric neuropsychologist in my area. She is a very caring and competent practitioner by all counts.  She expressed some concerns about referring patients to me.  She said while she felt the science would validate vision therapy in the future, she did not feel that there was enough scientific evidence currently demonstrating the relationship between the vision problems we treat, such as Convergence Insufficiency, and academic performance.  She felt that the science certainly shows that functional vision problems exist and that vision therapy would help alleviate discomfort associated with these vision problems, but that the science did not yet show that treating these vision problems would impact school performance.

I was happy to report to her that the future is here.  In fact, I would like to dedicate the next several “Science” posts to the great research being done showing the correlation between vision and academic performance.

The article I would like to focus on today was written by the same authors of the Convergence Insufficiency Treatment Trial.  In this original research article sponsored by the National Institute of Health these scientists validated what so many of us have known for a long time.  Convergence Insufficiency and many other functional vision problems not only exist but cause a host of problems such as double vision, headaches, eye fatigue, slow reading and poor reading comprehension.   The treatment trial found that in-office Optometric vision therapy is by far the best treatment to alleviate these symptoms.  After completing this research, I am sure they must have encountered some of the same skepticism elicited by my colleague.

Their latest research article found in the journal of Optometry and Vision Science demonstrated that children with symptomatic Convergence Insufficiency showed significant improvements in reading comprehension after being treated with vision therapy. To see  the article click here.  Sounds like an academic performance link to me.   However, their research is by no means the only research out there.  I am happy to report I was able to send many other research articles as well to the practitioner in my area and have to say that she responded very favorably.  I am excited to share more of these research articles with you in the coming weeks.  Stay tuned…

Boy reading a book

I hope to be blogging here more often.  I want to give a shout out to all of the COVD blog authors who put in so much time to getting the word out about how vision can impact the lives of so many.  Especially a thank you to Dr. Rochelle Mozlin whose dedication to this blog has helped the lives of many seeking to learn more about these critical and often silent vision problems.
