Not sure if this will work for you, but I played with a blind person before and the person with them would whisper what the cards were. Then the blind player would announce their action and the other person made the bets/folded the cards.
So if you have someone that's coming with you I think you'll be fine. As others said, casinos try to be very accommodating.
I don't believe they'll let the dealer be the person that handles your stack though. Maybe if you explain the situation to the pit they'll make an exception, but that would very likely be an exception.
