apoptosis

Question from a FitEyes member: Hello. I am impressed with the enormous amount of knowledge some of you have about glaucoma. You can teach the doctors a few things. I was diagnosed with glaucoma two years ago and as all of you am looking for ways to get better.
Can anyone tell me what happens to dead optic nerve cells? Does the body flush them away or do they remain in their shriveled state?
There also must be millions of stunted, dormant," hibernating" optic nerve cells, for otherwise how can microcurrent bring them partly back to life? This procedure is available in Germany but is expensive and seems to last less than a year.
I would like to believe in resurrection for the only alternative is stem cell therapy which is probably a dozen years away. I would appreciate any information.
