Wow, I'm sure you're feeling a dozen or more different things after finding out about the strabismus - I remember when we found out about our dd's vision challenges that I sooo so wished we'd known years earlier! II hope that your ds has as much success as our dd did with vision therapy - it really was amazing what a difference it made for her - not just in academics (reading in particular, but writing and other areas as well), but also in her daily life.
We didn't seek any further testing for LD at the time we found out about dd's vision challenges, but instead focused on her vision therapy. However, we made that decision because she'd been through a full neuropsych exam that included testing that would have given us clues re dyslexia or other typical learning challenges were present and there weren't indications of anything else that our neuropsych felt were potential challenges. If I were in your shoes today, I'd probably pass on further testing until you've had a chance to see if vision therapy works - *unless* you see something else in the previous testing that you wonder about. I took a quick look, and there are two subtests that I can't remember anything about off the top of my head, so I'm not sure if the scores for them would be impacted by vision or not (digit span and letter-number sequencing). The other subtests that your ds had low scores were tests that use vision; if you look up a test description and find that they don't rely on vision, I would at least ask the psych who did the testing if he/she feels there is something going on there, and possibly pursue some follow-up testing. I wouldn't worry too much about any of the achievement test scores - I'm guessing the lower scores there have an impact from vision challenges.
I also disagree with the therapist who feels that testing again next year isn't warranted. Vision challenges are huge! And you'll probably find yourself wondering, after your ds has been through vision therapy, if it's made a difference in any of these scores. We didn't pursue retesting right away, but our dd did go through a follow-up educational eval again this spring. It wasn't a full neuropsych workup, but instead ability+achievement testing and a bit of extra testing to determine whether or not she had any LD related to math ability because she struggles quite a bit in math. The ability test she was given this time around was the WJ-III Test of Cognitive Abilities, so I don't have any direct subtest score comparisons with her WISC - but - her scores across subtests were all fairly consistent, including the tests that had a vision component, so I"m guessing if she was given the WISC again her previously low subtest scores would no longer be low. She had WJ-III achievement tests both times and dang it, I was so focused on figuring out what was going on with her math that I didn't think to compare the achievement test scores from before and after VT - I'll have to do that when I have a bit of free time!
What were you told about how to proceed for the strabismus? All vision therapy? Any kind of corrective lens? Our dd hasn't used any kind of lenses, but I have a niece who is in her mid-20s who has all-the-time strabismus (sorry I don't know the technical term for "all-the-time" lol)... she wears contacts that correct her eye position, but she has had trouble with reading throughout her life in spite of having the strabismus successfully. There is dyslexia/dysgraphia sprinkled throughout my dh's family, and we all suspect she has some type of reading challenge that is unrelated to the strabismus but went undetected because everyone in her academic life assumed her reading challenges were all due to vision issues.
Good luck - I'll be interested in hearing how VT goes for your ds - and I'll be cheering him on!
