It is a nice thought, but, no, my sight is permanently going black. It was diagnosed in 2007 and has just continuously, gradually gotten worse. All of the different specialist doctors I have been to have all said the same thing, "it will either stay where it is or it will gradually get worse." It has taken a long time for me to get to this point which I am thankful for because I have been able to slowly adjust. Thank you for your kind thoughts.
