Hi! I don't have blindness per se, but I was unable to close my AN-side eye for almost a year after surgery. So I had to keep the eye heavily lubed during that time, which was pretty much like looking through Vaseline. And during that time, I was adjusting to the hearing and vestibular loss. Even now, 2+ years later, that eye does not tear and drain normally, and I often have blurry vision from excess tearing. I have definitely noticed that my balance is at its worst on the blurry days.
I have found that exercise helps. My physical therapist started me on core / abdominal strengthening, and after I was discharged from PT, I continued with Pilates, working with a personal trainer. As the core muscles get stronger, they are better able to help me compensate for the vision and vestibular deficits. Walking helps, too -- just not on a treadmill, at least not yet! And my balance has greatly improved from those first days when I was using a walker. But some days are better than others. Fatigue is definitely a factor. Even the weather seems to affect it -- my ENT believes it is related to changes in atmospheric pressure disrupting the inner ear. I'm like a walking barometer -- I know when a front's approaching Atlanta before the meteorologists do.
It sounds like you've been through a lot. I do think you will continue to see improvement in your balance. It just takes time. I'm past the two year point and still improving, even on blurry- eyed days. I've even started to jog, sort of
. Ever see the movie, Seabiscuit, about the race horse? True story. The scene where his owners first see him run, and ask the trainer, "Is he fast?" "Yeah, in every direction." Some days, that pretty much sums it up. But it's way better than a walker! Time and exercise -- they are your friends. I try to make the most of the things I can control -- exercise and getting enough rest. Can't do much about the weather.
Hope this helps. Hang in there! And if you're looking for a good movie, check out Seabiscuit! I will warn you, it's NOT a comedy. But talk about overcoming adversity? Wow, just wow. Not just the horse, either. You'll see what I mean
