Ocular Migraine
The cause of the migraine is thought to begin with arteries in the brain which spasm, precipitated by stress, hormonal fluctuations, certain medications, foods containing tyramine or phenylalanine (e.g., cheese, chocolate), fatigue, and alcohol. The result is reduction in blood flow in that artery, followed by blood vessel dilation over-filling of those vessels, causing the severe throbbing or "pounding" headache.
Migraines are also known as vascular headaches. The exact cause of a migraine is unknown, although evidence suggests involvement of the blood vessels of your head. They usually begin in the early morning or during the day with intense, gripping pain on one side of the head that may gradually spread. It reaches the peak of severity in minutes to an hour or two, and lasts for hours to days, unless it treated. It is often terminated by sleep.
