Ocular migraine occurs in the same way that a normal migraine does: by a sudden tightening of the blood vessels. However, these blood vessels are found in the retina.
Ocular migraine can cause temporary blindness, flashing lights, or a visual disturbance in your field of vision. Unlike migraines with aura however, the vision problems is only experienced in one eye. Being struck with ocular migraines can be frightening but it is not something to be alarmed about. Your vision usually returns to normal after 20 to 30 minutes even without medication. However, this is followed by a throbbing headache which is felt only on one side of the head.
Ocular migraine is a rare disorder, but some of the visual problems linked to migraines are not. It is best to know the other eye-related problems that can result to headaches to be able to prevent or treat them.
