Thanks for posting your query.
Are you sure that you are suffering from ocular migraine?
Do you have retro-orbital pain and loss of vision in correct eye?
Do you have sudden or progressive loss of vision?
If AVM is present then it will cause progressive loss of vision.
You should consult with neurologist
and should go for MRI
brain with angiography
is present then you should go for clipping therapy. If AVM is not the cause then you should take treatment for migraine.
