I'd make an appointment with the right kind of optometrist right away. To find one that deals with this sort of thing (tracking, etc.), go to www.covd.org . We've been through vision therapy for eye tracking issues and were very pleased with the results.

The other thing that comes to mind is that sometimes visual-spatial learners have trouble with spelling (so it is said; so far my two vsl's seem to be rather anal about spelling lol). See http://www.visualspatial.org/what_is_a_vsl.htm . For VSL spelling tips, see http://www.visualspatial.org/Articles/app2spell.pdf

Good luck!!
