Hello Kathie,
I think we all need to remember and remind ourselves that neuropathy is a very weird condition and not too well known by medical providers. There are no concrete causes and definitely no treatment. Each person will have different symptoms. However, funny you should mention vision as I just saw my neurologist on May 1st for the second time and it's the second time she's telling me to go to an ophtalmologist. I'm in the midst of making an appointment and just waiting for the neurologist to put in a referral so I can get a sooner appointment than July.
As for hearing, I've had pulsatile tinnitis in my left ear for a number of years now. I have no idea if neuropathy exacerbate that. So far I have not looked into it.
Wishing you the best and take care,
gus
