I was first diagnosed when I went to ER with Optic Neuritis. MRI showed a lot of lesions. Neuro and Opthalmologist called in to ER said it WAS Optic Neuritis even tho I had blood inside eye and sudden loss of vision in right eye. Follow up Retina Specialist diagnosed Optic Neuritis with possible ischemic vascular changes. Still have vision issues. Went to see Top Neuro Opthalmologist. She said it could have been Optic Neuritis but she doubts it because typically you don’t have blood in eye with Optic Neuritis. So I’m confused if I did or did not have ON.
