SoulSource,
I am sorry to hear about your mother's eye condition. You may want to look into using EFT to help with her vision problem, epecially if a lot of it started with her emotional fear. I myself have not tried this program, but I listened to some of the audio transcipts on the website, about the research work on testing EFT with vision, and the author of the book had some very convincing results to report. I wish you and your mother the very best.
