Most ocular migraines last a relatively short amount of time, frequently less than an hour. In some cases, headache accompanies the loss of vision, while in others, the headache comes before or after the migraine. These are more frequent in women, people with a family or personal history of migraines or other types of headaches; people with lupus, atherosclerosis, depression, epilepsy or depression; as well as all people under the age of 40, notes WebMD.
The primary cause for an ocular migraine is a sudden constriction of blood vessels, cutting down on the flow of blood to the eye. After the migraine ends, vision generally returns to normal. These incidences are generally harmless, but they potentially cause damage to the retina and the blood vessels that lead to it. Because the symptoms resemble those of some more serious conditions, such as stroke or eye diseases, an individual who suffers from them needs to undergo a thorough medical evaluation to rule out more severe possibilities, reports WebMD.Learn more about Vision
