Hm.
First, even if she had one litter, that most likely wasn't recently but when she was young. No way to tell if there was one at all.
That means she went a very long time without litters. Lots of time for things to get stiff and rusty, and for fat to accumulate in the wrong places. Living in a cage isn't an active lifestyle.
So, even if you can get her pregnant, which may proof difficult, the risk that something goes wrong (like, a lot of suffering and dying) is rather high under this circumstances.
Second, that runny eyes. That might be something benign or not, or it might be diet related (like blocked tear duct from overgrowing teeth roots due to being fed hard stuff like grains), or it's genetic, at least the disposition to get it.
I wouldn't breed a rabbit with an obvious health problem, except for meat.
It's not unheard of that does at such a high age had successful accidential litters, but if she wasn't bred at least once a year until now I wouldn't try it on purpose, unless maybe some rare, very desireable genetic traits were at stake that were worth a shot to save.
