A member asked:

Ive had one ocular migraine previously which permanently reduced the vision in the corner of my left eye. will this show on a brain mri and if so how?

Need sub-specialists: A migraine should not leave a permanent blank spot in vision. Have you had both a Neuro-ophthalmologist and a Retinologist examine you?

This is rare: A "migraine" that results in a permanent deficit would be extremely rare. You need to be evaluated with formal visual fields by an ophthalmologist to make sure what's going on here. Migraine would not show up on MRI but something like a stroke would. Get checked out.
