Yes...very common in brain injuries unfortunately. I have improved, including the photosensitivity. I need sunglasses outside always, but not so much indoors anymore. Progress! Prisms helped a huge amount. I still have lots of pain and pulling behind the eyes if I use them too much (ipad, etc.). Many things can recover with the vision - one thing that rarely does is the vertical heterophoria (not converging up and down).
One thing that my neuro-opth told me is that vision problems usually indicate a brain stem injury, which can require a much longer recovery time. Didn't want to believe it at first but I do now, especially since other parts of the injury are healing a bit better (headaches, etc. ). It takes quite a knock to get to the well-protected brain stem.
Having said all that, if that is true, we are then among the very lucky, because it could have been so much worse. I try to focus on that good luck, and not the bad luck that put me here in the first place
Re Dizzyness....vestibular and vision are intimately connected ...as in the vstibular occular reflex, etc. They all converge at the same place. So vestibular therapy goes hand in hand wi vision therapy!
Good luck...keep healing! You will feel better bit by bit, I am sure!
