The Mystery Behind Ocular Migraine Causes
Most scientists believe that the causes of Ocular Migraines are quite similar to those of a traditional migraine. The only difference is the change in the area impacted by the blood supply. Traditional migraines usually generate from the surface area of the brain, but the cause of ocular migraines is the reduction in the blood supply to the vision center of the brain.
Some of the main causes of ocular migraine include anxiety, chocolates, travel, lack of sleep, bright lights, and artificial sweeteners. Another interesting facts is that sever ocular migraines have been shown to be triggered by caffeine, more specifically highly sweetened coffee. In fact, a more common ocular migraine cause is a food or environmental trigger – so it’s best to try to identify and avoid them. Seasonal allergies can also act as triggers. Additional ocular Migraine Causes are certain foods, alcohol consumption, medications, or changes in hormone levels due to menstruation.
So Do You Know If You Have Ocular Migraines?
Saddly enough about 28 million Americans each year suffer from migraines every year according to statistics. Some of the most common symptoms of traditional migraines include having sensitivity to light, nausea and terrible head pains. But did you know that there are 150 diagnostic headache categories? Ocular migraines are only one type of migraine that involves the eyes, with or without an accompanying headache. Image distortion generally begins in the center of the image and then moves to one side. Images "grey out" or look wavy, and sight may be temporarily lost. This type of migraine usually starts with the small blind spot within the peripheral vision, and the spot increases gradually over five to ten minutes to encompass the full peripheral portion of the vision, resulting in object fuzziness or complete blindness.
Ways To Avoid Ocular Migraines
Make sure that you eat regular small meals as hunger can sometimes trigger the ocular episode. Stress is one of the leading causes of ocular migraine, so learn different ways to relax such as yoga, meditation or tai chi.
At the onset of ocular migraine, it can be very disturbing to become slowly blind in one eye, but the key is to keep calm. Find a quiet and dark place, and rest for 20 to 30 minutes. If you suffer from frequent ocular migraines, consult your doctor to identify and then eliminate the causes of ocular migraine. A simple analgesic such as aspirin may provide the immediate relief. Cafergot is the combination of caffeine and tartrate, and is usually quite helpful. Ergotamine is a useful migraine medication, and is helpful in treating the headaches and other associated side effects such as vomiting, nausea, tingling sensation and cramps.

There are some problems here.
First, there are now nearly 37 million Migraineurs in the US.
Secondly, the term ocular Migraine is used by different people to mean different things. Most people, to avoid confusion, follow the gold standard for headache disorder, classification, the International Headache Society’s International Classification of Headache Disorders, 2nd Edition. Under their classification system, there is no “ocular Migraine.” Many forms of Migraine can have visual symptoms — Migraine with aura, Hemiplegic Migraine, Basilar-Type Migraine, and Retinal Migraine.
It’s good that more information is becoming available about Migraine disease and the forms of Migraine, but it is more helpful when the information is accurate.
