t might boost the capacity of healthy RGCs to form new connections within the optic nerve, to compensate for any damage that had already taken place.
However, nerve growth factor cannot rescue RGCs that have already died - in common with brain tissue, the optic nerve cannot regenerate.

I had to start taking drops in my eyes again to control the pressure. A year ago I had laser surgery and drops then I went off them them for almost a year. I went for an eye exam 3 months ago and the pressure was fine. Last week I went for a routine field vision and the pressure was through the roof. They said untreated I would have been blind within a year. Vision is so precious. Have your eyes tested.
