I was diagnosed with ON right eye in 2006 vision never returned and no treatment. ON has now occurred in left eye I was given IV steroids with no change. I'm now on cartia 100mg and they are saying ischemic neuropathy maybe. It's been a month of testing and prodding and I feel I've been put in the too hard basket. I have cut out all inflammatory foods and taking various supplements to reduce the inflammation. I don't know where to turn for help.
