I have a scheduled MRI next weekend which is 6 weeks after symptom onset. I attended the eye hospital with suspected retrobulbar neuritis which is optic neuritis behind the optic nerve. However when I returned for a 2 week check up, the Dr who examined me said my optic nerve appears to be firing- when he shone a light in my eye he could tell it was reactive. He suggested my symptoms were caused 'further back' meaning the brain. I am a little confused because all my symptoms were classical optic neuritis - pain on movement, blurred vision , changed colour and depth perception. I have so many questions! Have people had anything like this? Could I have inflammation/lesions which resulted in these symptoms but are not a type of neuritis?? I'm also worried that when I have the MRI, nothing will show up! What's the window of opportunity for relapse activity or damage to show on a MRI? I still can't see properly in my left eye... Thanks for listening to me! 🤯
