I'm so sorry for your loss. I lost vision in my left from NAION and last eye visit has me at 20/200 vision in that eye. So far good vision in the fellow eye. This is the worst disease with no options for treatment. I've been to two neuro-ophthalmologists and they confirmed the diagnosis and wished me well (they were kind, but couldn't do anymore than diagnosis the condition). Stem cell surgery might be an option at some point in the future; however, research costs money and this condition is fairly rare so I'm guessing the money is just not there. It's shocking to go to bed with good health and wait up to no/limited vision. It's been a year and I still feel like I should be in a better place to accept this, but still not there. The fear of losing my vision in the other eye is a daily fear. There is nothing I can really do health-wise to alleviate the anxiety since I don't have any of the risk factors. Sometimes I feel like a sitting duck...just waiting.
