Ego and Intraocular Pressure in Glaucoma (was Timeline for reversing glaucoma damage?)

I've never really heard anybody give an educated guess on when we may really have the ability to reverse the damage done by glaucoma.. Whether through stem cells or any other medical advancement ... can anybody reasonably predict a timetable on being able to repair the damaged nerves?

I'm especially interested in this because - at 55, and in good health otherwise - I have pretty bad glaucoma. I lost 90% of the vision in my right eye, and maybe 50% in my left before I even noticed any problems.  I sure wish I'd been paying attention ...
