My Mom had Peripheral vision problems in her left eye. Tests were done to see if she had a stroke, she didn't. It was determined it was the Denentia. When she walked, she went off to the left.

Strokes can effect vision too.

I think interesting in terms of research, but because a lot of eye exams are subjective, and those with dementia cannot participate in subjective stuff, I think will take some time to research. They do say there is a way to assure that you "may" be more prone to dementias, and closer to death. And that's balance. Lower brain control. And seems a bad indicator. Sorry to say my balance sucks, but at 81 if I got today no one will say "Oh, dear. The poor thing died so YOUNGGGGG".

Ummm...Everyone older than 81 would say "Oh, dear, the poor thing died soooo young." 🤣

Interesting article.
What might also be happening is that the information that eye takes in may take a while for the brain to interpret. So What I see now might not "register" for 30 to 60 seconds. If that is the case then it is easy to miss a step, a turn, or who that person was that just said Hi.
And as the article mentions other health related factors enter into the equation.

I don't know about dementia causing blindness, but it can cause a variety of eye issues as discussed in the article linked above.

Good luck to you.
