Our first vision therapist told us that eye muscles continue to improve for a period of time after the exercises are stopped, which it did for my son. So it might not hurt to give it a rest especially if it's adding stress.
What we did was stop for a period of 3mths after which DS went for an assessment which showed improvement. But he still had some problems with near-far tracking. We found a second vision therapist who addressed this condition (he prescribed daily home exercises on a computer program - a lot cheaper). When we went for an independent review 6mths later, his situation improved further.
