Rarelly: A migraine can cause blurriness or loss of vision in one area of the visual field usually not lasting over 20 minutes and is often followed by a headache..

If "classical": A migraine variant termed "classical" migraine does cause auras prior to the headache with sparkling lights, areas of decreased vision or even loss of vision over right or left half of visual field, followed by headache. Otherwise eye muscle control is maintained. In another case, horton's cephalgia, the eyelid may temporarily droop.

Rarely: There is a rare form of migraine in which the eye muscles do not work. It is called an ophthalmoplegic migraine.
