Can you get an independent assessment of the problems you're aiming to treat? (I.e. an assessment not done by the very person who wants to sell you more expensive therapy?)

ADHD meds would probably have different effects than the vision therapy; not knowing your situation, I'm curious as to why they would be the next option. I think you'd have to clarify what the problem is, what your goal is, then decide what path is more likely to get you where you need to be.

Is there a doctor guiding the overall care?
