Hi. I'm online and happy to answer your question today.
in addition to the optometrist is your son being treated/seen by an ophthalmologist?
I see that you are offline. We can use the Q&A system to 'text message' each other. An email will be sent to each of us every time something is posted to this thread.
I am a teacher of students with visual impairments. Student has not seen opthalmolgist in two years, but that is the source of the diagnostic info I provided. Optometrist's report did not address these issuses. Also, might add that noted a reference in that ophthalmolgy report to V-pattern strabismus (distance)
