I have a dd who had severe vision challenges related to convergence and tracking when she was in early elementary. I can't help you with an analysis of the scores as I'm not familiar with the DAS II - although I wonder if there are subtest scores provided ever for the DAS II? The subtest scores on the WISC were helpful in identifying my dd as having vision-related impacts on scores.
Are you planning to pursue vision therapy? Are you comfortable with the vision diagnosis? VT and convergence issues diagnoses are sometimes a bit controversial, but for our dd VT was extremely helpful. If you have any specific questions about VT or convergence issues etc, let us know - there are several of us on the board who've had children with vision issues.
Did the psych who diagnosed him with ADHD utilize any behavior surveys or other means of diagnosing the ADHD? If the diagnosis was made on observations during the evaluation only, I'd be somewhat unsure of the diagnosis - the vision challenges our dd had at the same age made her appear to have ADHD, but those symptoms disappeared when her vision challenge was remediated.
Best wishes,
