Let me tell you about second opinions... my Dad was diagnosed with macular degeneration in the 70s at Wills Eye Hospital in Philadelphia. He (stupidly) watched an solar eclipse when he was in the navy in the 60s. He has a black spot in the center of his vision. This usually points to macular degeneration. Well, the experts were wrong. He burned his retina, and stilll has the black spot in the center of his vision, but if it were macular degeneration, he'd be blind now, as it is progressive.
Hopefully, the diagnosis was as wrong as my Dad's.
However, if it isn't... contact your local Lions Club. Until I was a member of that organization, I'd have never believed the programs they have available for the blind and almost-blind. If the club is like mine, they will go out of their way to assist you in any way that they can, including helping you to pay for canes, leader dogs, etc.
One man that I know who lost his sight as an adult focused his efforts on bringing a young woman from the Ukraine to our area. She had received a full scholarship to a local university for her masters in sociology. She still needed to raise $13,000 before the INS would grant her a visa. Her family would not have been able to come up with that kind of money. He single-handedly raised the money... found a place for her to live... and helped her to get her student visa. Now that she's here, he's working on finding her an affordable car so she can get around better.
Blindness is not a life sentence, although it certainly sucks when you're used to having it. I wish him well in this new chapter of his life... and you as well. If you see him start slipping into a depression, make sure he gets some medicine from the dr so he can keep his head on straight.
