A Common Vision Problem
I finally managed to put together a Page discussing the Convergence Insufficiency Study that was published in January of 2005.
There you will find a link to the complete article describing the study, as well as a link to a very useful questionnaire used to determine if your child has the symptoms of convergence insufficiency. I’ve also linked to the three charts of results that were obtained in the study so you don’t have to plow through the whole thing yourself.
The study appears to have been well designed and is, I believe, part of a larger study being done at several locations to determine whether convergence insufficiency is best treated by vision therapy. What is particularly impressive is that the article was published in the Archives of Ophthalmology in spite of the Academy of Ophthalmology’s longstanding policy statement opposing vision therapy as a viable treatment. This is, in some sense, progress. Maybe someday everybody will get on the same page with all this and we can start to catch all the children that are currently being missed.
Again, the study is discussed on the Page Convergence Insufficiency Study
