I'd use a pee pad upstairs and let him take his time learning to use the stairs. His vision might even get worse over time, so having him pee pad trained may come in handy. I wouldn't push him, even gently. He's needs to learn to do it on his own, pushing might even make him more scared. Train him by tempting him with a treat, like a tiny piece of boiled chicken. Just a couple of steps at a time and give him a treat with lots of verbal praise. Make sure the steps are well lighted, and I agree with Yorkiemom, tell the breeder about this.
