Knowing Ocular Migraines

Causes

Ocular migraines are believed to be caused by blood vessels constricting and reducing blood flow to the eye. If a patient is able to get to the doctor when experiencing one of these migraines, they will be able to detect if there’s decreased blood flow to the eye. Some reports indicate there is a potential cause of ocular migraines in abnormal serotonin levels, which can influence the constriction of blood vessels and decrease oxygen to the brain.
