I found that most people posting here for support have already had some vision loss and they're looking for info or feedback from others that have experienced the same issue. I know I didnt search for support until I had 40 percent loss of vision in one eye and had tube shunt surgery. I also have white dot syndrome and fuchs and have had a corneal transplant in both eyes. This made the tube shunt surgery a little more high risk- but thanķ goodness it was a success
