What is a visual migraine?
Visual migraine is a common cause of temporary vision problems that may or may not be accompanied by headaches. The episode occurs when small blood vessels that feed the retina reduce blood flow to the eye. In most cases, the visual migraine affects only one eye and takes less than 30 minutes. Visual migraines are usually harmless to human health, although an individual who is experiencing frequent or serious episodes should encounter a doctor to eliminate more serious problems and discuss ways of coping.
blood vessels can be caused by a number of different factors. Most episodes are related to seemingly harmless causes, such as getting up too quickly or engaging in a slight exercise. Hormonal imbalance, viral infections and blood disorders such as anemia of sickle cells can also cause visual migraines. Some people also experience symptoms that are triggered by undesirable prescription or over-the-counter drug reactions.

Dispant images can cause a person to become dizziness, nausea or lightened. The visual migraine usually takes less than five minutes, and problems rarely persist for more than half an hour. Eyes are returning rapidly, although symptoms of nausea or slight headaches may persist.
It is important that a person who experienced a visual migraine visits an emergency room or plan a meeting with an ophthalmologist for a thorough evaluation. The doctor may check the symptoms of eye disease, vascular disease or separate retina by performing diagnostic imaging scanning and carefully examining the eye. It can perform blood tests to look for toxins or signs of anemia.
The treatment of visual migraine depends on the basic cause. Patients who do not seem,They usually do not require medical care that they have health problems. They are simply sent home and instructed to return if the problems repeat for further analysis. If the reaction to the drug is responsible, the patient may need to switch medication.
Visual migraine, which affects both eyes at the same time, is probably a symptom of a more conventional definition of migraine. This phenomenon is called aura and usually prevents the onset of severe headaches. A person who is experiencing migraines with auras should look for immediate medical care to obtain a thorough neurological screening and learn about different medicines to reduce the pain and frequency of episodes.
