I probably not "adding" much more, but here's a couple thoughts.
(And my son is hg+, so not same. How're ever, stronger in VCI then PRI)
My ds7 was tested 1 year ago as a k student, WJ showed reading at 3rd grade, math 2nd grade. Tester said she expected to increase with exposure (I was providing no math and limited reading.) It was also recommended to us to see a developmental optometrist. This vision therapy has changed my son. He is able to read and do work much easier with great endurance.
I am so happy we had evaluated as I'm sure it must have been very stressful to not be able to see well. He never voiced a problem, but I'm sure when you've always had a problem, it seems normal.
