Ocular migraine is an uncommon name for a chronic disease, individuals are used to hearing scientific terms when referring to a medical disease. Accordingly, the different terms of the migraine forms give a clue to the believed source, cause or nature.
Ocular migraine is also known as visual migraine, acephalgic migraine, silent migraine and eye migraine. Physicians, however, refer to it as migraine without a headache pain. To better know it, one have to know the phases of the simple migraine. The first stage of the simple migraine is the prodrome. It is the time when the symptoms of the ocular migraine symptoms start to occur, such diarrhea, confusion and irritability, thirst and food cravings. The next phase is this migraine aura and visual disturbances, a time when the visual symptoms are felt. During this stage, other manifestations may also arise. There are many physical symptoms of the ocular migraine such as: difficulty in moving, numbness, slurred speech and tingling sensations. The head pain then proceeds after this aura phase, which may last up to four days. When it is over, the sufferer may feel tired for two days. Note that: not all the sufferer of the migraine goes through all these stages during the migraine symptoms. Migraine can occur without auras or headaches ( which is what occurred with this migraine ).
Like other migraine types, this migraine has its own episodes set consisting of feeling of confusions, euphoria, irritability, chills, fatigue, increased urination, food cravings, thirst, nausea, vomiting, diarrhea and appetite loss.
The most obvious symptom of the ocular migraine is the aura, which is a visual disturbance that are felt by the sufferers. The visual symptoms of the ocular migraine are seeing the following: wavy lines, flashing lights, blind spots, dots and jagged lines. The patients may go through distortions in smell or taste, numbness sensation and tingling in other parts of the body.
Doctors believe that it is resulted from the abnormal process of the brain nerve cells. Migraine visual disturbances result from the conversion of the activities from the overstimulation to the depression of these nerve cells. The reduction of the activities spreads across the brain, starting from the brain vision center to the sensation center. This reaction is started by many factors called ocular migraine triggers. The aura reasons are: bright lights, certain foods, weather changes, loud noises, caffeine, hormonal changes, stress, inadequate sleep, alcohol and skipped meals.
