Hi Dufferooni and welcome to NeuroTalk.

I know you have not been diagnosed with Multiple Sclerosis but many on the MS forum have dealt with Optic Neuritis (ON) and could be of help in answering your questions.

I have MS but I have never had ON.

My sister as well as 2 of my friends have had ON but do not have MS. My sister's ON cleared up on it's own in 3 weeks and she has never had another episode of ON.

I hope you were put on IV steroids? Oral steroids are not recommended for treating ON.

Anytime there is an issue with your vision please see an Optometrist or Ophthalmologist as Primary Care Physicians really are not very good at diagnosing vision problems. It is unfortunate that your Primary Care Physician did not refer you directly to an Ophthalmologist at your first visit
