Could migraine headaches make someone permanently blind?

Accurate Diagnosis: A migraine headache should not cause a permanent loss of vision. However, other types of headaches could be associated with permanent visual loss so a proper diagnosis is crucial.

Beware of this: The crucial head pain which can lead to blindness is giant cell or temporal arteritis, which can be recognized by blood testing for sed rate and c-reactive protein, which may lead to temporal artery biopsy for confirmation. Steroid treatments can prevent blindness. Headaches may also accompany cerebrovascular disease, and a stoke could cause loss of vision.
