Thank you for the replies.

Mark - this is a workman's comp case - which is a total disaster as you know, so I highly doubt they will pay for anything. I may have to go a different route and have my current work insurance (which is a cadillac policy) pay for it as you suggest.
My thing with getting this sort of therapy is that it would likely wipe me out (Physically) and because I travel for work ( and work from home when not traveling), I don't know that I can make this sort of commitment. Thus - why I asked if it was reasonable to believe the vestibular issues would correct themselves over time - without therapy?!?!
I am probably asking a question that only God knows!

The Dr made the comment that this sort of eye issue needed to be addressed before an 18-24 month time period AFTER the incident occurred, which makes me think it wouldn't resolve by itself. There is obviously something to the vision therapy, but it seems like its similar to a back surgery where the Dr only gives you a 60% chance of it actually helping.
