    Yes, you can get pupils dilate because of a migraine. Migraine is a chronic disorder characterized with a moderate to severe headache due to the constriction and expansion of blood vessels in the brain. Ophthalmoplegic migraine can cause abnormal paralysis of the motor nerves of the eye and dilated pupils.

    Generally speaking, it is possible for migraine to cause dilated pupil. Migraine is commonly associated with headaches, described as an intense pain of one temple. There are plenty of nerves and vessels in our brain, which is very complicated combination. Some study on migraine said the dilated pupil is caused by Postganglionic sympathetic nerve spasms during migraine. But the dilated pupil is only a temporary symptom, which can disappear without treatment. Actually we know that dilated pupil is related to nervous system. Once nervous system is sitmulated, it is easy to get pupil dilation.
