It usually interferes or obscure vision. The seemingly hallucination episode usually lasts for 15-20 minutes and may or may not be followed by a headache. You might think that you are seeing things or getting insane. This condition is known as visual migraine. Migraine is thought to occur when dilation and constriction of the arteries in the head lead to an extremely painful headache. Visual migraine, on the other hand, is a condition believed to be of the same cause as of migraine but instead of the spasm affecting the surface of the brain, it affects the ocular blood supply resulting to vasospasm, a spasm of arteries behind the eye, which shuts off blood flow to the optic nerve.
Visual migraine is like a temporary loss of vision associated with bright flashing lights and jagged geometric lines. It is not a blacking out of vision or a total blindness. A visual hallucination is actually a visual perception that does not involve the external stimuli. Thus, the person’s frequent jagged geometric auras qualify as visual hallucination.
More often than not, visual disturbance in visual migraine usually starts in the peripheral vision consisting of almost circular, jagged, shimmering spot which enlarges and moves to the center area which usually obscure the vision. The light is described to be of pale pastel shade. This episode disappears after 15-20 minutes and a mild headache may or may not occur. Although there is no known causes of migraine, it is believe that stress can trigger migraine. Eye-related headaches occur after extended periods of reading, watching television, computer work, or anything that requires intense concentration. Any stimulus that produces a reaction is called a Trigger.
Usually, this condition resolves even without treatment and many people never have another episode. Some people may continue to have them. An examination of the eye is important to rule out any other causes for these symptoms. In very rare situations that these symptoms continue to recur on a regular basis and interfere with one’s quality of life, then treatment is available with pills that both decrease the frequency of attacks as well its severity. Treatment usually begins upon consultation with an family physician or neurologist. There are several over-the-counter and prescription medicines that can provide migraine remedies or aid in relieving symptoms of attacks when they happen. For most people, treatments to relieve stress prove to be equally helpful as migraine remedies.
