I learned about vision therapy here from Eowyn's posts and got evaluated and then paid out of pocket for therapy sessions for several months. It helped a little.

But the hormone replacement therapy for the deficiencies that the concussion caused has significantly improved my vision.

My vision improved so much that only a few weeks after taking them, the neuro-optometrist that I was seeing for the vision therapy told me it was a rapid improvement (he was very surprised!) and that I didn't need the therapy any more. He was even more surprised to learn that my vision had even improved more after our 6 month follow up visit and I hadn't been practicing at all - the hormones just fixed the way my brain was seeing the visual data.
