Disappointment / irritation

Hi everyone! I just came back from my eye specialist. And it was the follow-up from when he diagnosed me with optic Neurosis back in february. And all the appointment was is that they did vision test on the screen in front of me and when he came in he said you know everything's pretty much the same so no more follow-ups like that's it. And I need to know or if anyone can help me is optic neurosis permanent if it doesn't dealership any Improvement after 12 weeks? And is nystagmus permanent? Because he was very just nonchalant about the whole thing and told me this is it and just deal with it basically. So if anyone knows I would greatly appreciate it. Thank you!
