I was 34 with my first bout with optic neuritis (now 43). I'm not sure I really missed anything in the 9 years as I don't have any significant symptoms and sure hope it stays that way as I hear some are symptom free for very long stretches. The things the neurologist asked was any feeling of pins and needles, lack of balance/coordination, any bladder control issues. I guess I do occasionally have the pins and needles in my feet but it's certainly not noteworthy and I've never noted any big issues with balance/coordination other than normal clumsiness. I assume you had an MRI when you had optic neuritis? I wouldn't stress about it as I'm pretty darn convinced that stress is a huge trigger in auto-immune diseases and both episodes of optic neuritis were following stressful time periods for me. Did your vision return after the optic neuritis? My left eye was impacted the 1st time and it took several months but went back to normal. My right eye was impacted this time and it's still not 100% back but holding out hope that it will improve more over time.
