So yea... A broken orbital socket and glaucoma have absolutely nothing to do with each other. Physical damage can not cause, not exacerbate, glaucoma.
But it can have an impact on the eye pressure which is a big issue if you're suffering from Glaucoma. I have a friend who had an accident involving the area around her eye and her eye pressure took months to go back to normal. So yes, it can have an effect on the nerve. Not saying it does in Bono's case, I hope it doesn't, but it's not that far fetched. Facial injuries are always tricky, especially if the area around your eye is involved.
