| Here's a much better (if a bit scarey) informational URL. This one is much more comprehensive, but going along with what Heather said, it reckons that even people with advanced retinopathy can have up to 90% chance of restoring "useful" vision restored.

There's a ton of stuff on google on this. It's of particular interest to me cos my Dad has Glaucoma (which is inherited on the male side, I believe - could be wrong).
Is there anyone out there who has a personal experience of this, or treatment of the condition (at any stage) who would be willing to share?
