I would keep her alive for sure, unless she becomes dangerous to herself or others.
My, much older, mare is nearly blind and she functions super well. She needs a little extra "help" at times, bells on pasturemates, etc, but she's ridden often and has no major life issues related to her sight loss. In a new large pasture, I have to section it off so she doesn't get too worked up about having a large new space but otherwise she does just fine in a 6 acre pasture.
I might put a small bell on mom - braid it into moms' mane or something, but just take it day by day.
I also wear my keys on a carabiner attached to a belt loop on my jeans, around my mare, (wearing a bell would work too) so she can keep track of me. I used to not do that and, while she did fine, there always seemed to be an element of stress about where I was for her. Now that I jingle, she's A LOT more relaxed around me.
I really love that my mare is nearly blind. I would obviously love it if she were fully seeing but blindness is not nearly the death sentence most think of it as. She does take a bit more care than the average horse but that's ok for me since I like feeling needed and she definitely needs me! haha
ETA- I totally second SR and getting a full exam to make sure nothing else is wrong. For sure.
