I have a 6 year old sow, and I've noticed that she has been following her nose more than she used to. It's hard to explain what she is doing, but she seems more cautious than she used to be, and often misses hay or a piece of vegetable on the first try. It looks like she is feeling/sniffing around for it. Other than that, it doesn't seem to be bothering her at all. She's still acting normally, eating, drinking, and lounging around.
If it makes a difference, she has pink eyes.
