I assume that you are referring to ischemia in your brain (white matter disease). I have the same thing. Balance is definitely a possible symptom, as it is in my case. Sometimes I am wobbly (my wife's technical term!) and light headed and as a result have had a couple of falls. My wife won't let me on a ladder without supervision. As far as vision, I have noticed a similar degradation but can't distinguish if it is from the ischemia or the normal aging process.

At my last neurologist appointment as he put me through the normal tests I joked that I hope that the police don't pull me over for anything because I wouldn't be able to pass the field sobriety tests even if I haven't had a drink for a week!

Good luck and hope that your disease progresses slowly.
