I've had Optic Neuritis attacks twice now. The first time was the worst, the second wasn't as bad.

I went to an opthamologist who examined my eyes. She noted no damage to the optic nerve, however I did indeed have O.N. My neurologist confirmed it as such, and after a course of Solu Medrol and prednisone, it went away finally after about a month.

It was like a huge sun spot in my left eye, vision was reduced by 80%. I had pain when I attempted to look to the left. My eye felt dry/itchy constantly.

The blurry/ghosting thing - this I have regularly. Some days it's better than others. I have also had the hatched/cross hatched vision disturbance. Generally these visual oddities show up when I'm tired, stressed, the weather's gone wonky with pressure changes, etc.

The most baffling to me (other than the rest) is out of my middle left eye vision, I oftentimes see a bright blue dot randomly. I don't go a day now without seeing it. It will just flash for a split second, and vanish. Eye doc and neuro both don't think it's a big deal, neuro figures it's migraine doing it. Who knows!
