Oogmigraine (Ophtalmic migraine)
Oogziekten.info
The term "migraine" usually brings to mind a severe type of headache. But visual disturbances with or without headache pain also can accompany migraine processes thought to be related to changes in blood flow in the brain. These visual problems associated with migraines technically are known as ophthalmic migraines, but are much more commonly (though incorrectly) called ocular migraines. Because most lay people better understand the term, this article refers to the condition as "ocular migraine."
Migraines can be produced by the body's neurological responses to certain triggers such as hormonal changes, flashing lights, or chemicals in foods or medications. One result of these triggers may be an intense headache that, if untreated, can last for hours or even days. During migraine processes, changes also may take place in blood flow to the area of the brain responsible for vision (visual cortex or occipital lobe). Resulting ophthalmic or ocular migraines commonly can produce visual symptoms even without a headache.
