Helping a parent process through what the eye doctor said

Last week I received a call from a home-schooler who found my Eye Can Too! Read website and wanted to know which book she should order for her son. She recently took him to a developmental optometrist who diagnosed a cluster of visual diagnoses which do indicate a need for vision therapy. But the mother had not been given enough information to understand what had been found or what the therapy would accomplish. We talked for more than an hour. While the doctor did not use any of the normed diagnostic tools with which I am familiar, I could tell by the description of her assessment activities what she had done. The therapy assignment for the first several weeks was to use a Marsden Ball to introduce appropriate control of Pursuits, one of the two ocular motility skills we address in therapy. The therapy is only done at home facilitated by the parent - the mother was instructed to swing the ball three times in each direction for each eye once per day. She was to do nothing more for now. We concluded that her son would benefit from using either the Purple Book or the Yellow Book and since the activities are academic in nature, designed with home-schoolers in mind, they could be used without compromising the therapy prescribed by the doctor.
