A possible cure for macular degeneration

Weekly competition brief: a good news story.
Well, yesterday, I saw on the news a story about two people, who had their eyes injected with stemcells. It is hoped that, in due time and after lots more tests, this will cure age related macular degeneration, where the cells in centre of the retina die off and cause blindness in the form of a growing blind spot.
This is how sufferers see the world, so wouldn't it be nice if it were possible to cure it?
