I am so happy to see there is a group who is experiencing non-arteritic ischemic optic neuropathy. It is such a rare happening and most people don't know anything about it. Mine happened to me over night in 2011 in my right eye. It just happened again in my left eye but has been a slow process. From everything I have read it is a wait and see what happens. I was scheduled for cataract surgery when this happened and am hoping for clearer vision after the surgery.
