From what I read when googling ,there is no albinism in danes (though there are in some animal species). I do not think this girl was blind, she watched us very intently, and when they passed us on the trail the dane kept looking back at my dogs with interest. I didn't chat with the owner so I do not know if she was deaf but from what I read the deafness that is common in whites and double merles is caused by lack of pigmentation in the inner ear which causes the hair follicles that conduct sound waves to fall out and thus result in deafness.
