If the attacks continue and over the counter medications do not help, a prescribed medication from a general practitioner or neurologist may be needed. Once a stroke is ruled out, educating the patient about an ocular migraine and how to help avoid them will help calm the patient. It is a must to bring these patients in quickly to make sure that they are not having a stroke due to the similarity in symptoms. Can you have kaleidoscope vision but no headache Short answer: Yes. Doing this can help avoid the migraine attacks. If a patient can figure out their trigger, they can try to avoid them as much as possible. With migraines there are often triggers bright lights, flashing lights, eye strain, spending extended periods in poor lighting situations, driving for prolonged periods. This can be due to a reduction of blood flow to the retina. Retinal migraines are the same type of visual disturbance but happen in the back of the eye. The abnormal activity spreads across the cortex at a slow rate of about 3 mm per minute and this spread is responsible for the growth and movement of the visual disturbance over the period that the aura lasts, which ranges from 20-60 minutes. Auras are the result of abnormal electrical activity involving regions of the cortex of the brain. The cortex is divided into four lobes, the frontal, parietal, temporal, and occipital, which are each responsible for processing diverse types of sensory information. It is responsible for the higher thought processes including speech and decision making. The cerebral cortex is made up of tightly packed neurons and is the wrinkly, outermost layer that surrounds the brain. These auras happen in the cortex of the brain. Many patients will see flashes of lights, decreased vision, or even temporary blindness.Ī migraine aura can be overwhelming and nauseating. Retinal migraine symptoms are much more intrusive. A retinal migraine is a visual disturbance that can occur in one eye before or during a migraine attack. The second type of ocular migraine is a retinal migraine. This happens to approximately 20% of patients who suffer from ocular migraines. The auras can cause head pain or headache, but the duration of the headache is usually short. These auras can also affect other senses and can interfere with a patient’s speech, motor skills, and other central nervous symptoms. But these impairments only last a brief period, 15 minutes to 60 minutes is very normal. This type of migraine will include the visual disturbances, such as the blind spots, flashes of light, and odd patterns. There are two main types of ocular migraines, one is Migraine with Aura. In some people, fear produces excessive sweating, trembling, and nausea which can also cause a headache or migraine attack. Fear causes increased stress which usually leads to an attack of headache or migraine. These ocular migraines can also be followed by head pain, but in some instances, it is only the distorted vision. Fear is another common cause of headaches and migraine. The disturbances can be blind spots in vision, zig zag lines, flashes or pulsating lights, neon shapes, or kaleidoscope-like images may appear. ![]() Postictal headache, often severe and indistinguishable from migraine, occurred in two thirds of the patients, even after brief visual seizures without convulsions. One patient had ictal vomiting as an occasional symptom. These are migraines that cause some type of visual disturbance. Ictal blindness ab initio occurred in 2 and ictal, mainly orbital headache in another 2 patients. There are many types of migraines, including different ocular migraines. In most cases, the cause of the vision loss can be something as simple as a migraine, but any patient with sudden vision loss must be referred to the doctor. For severe or frequent headaches or migraine attacks, essential oils may work best as a complementary treatment to prescription medications. Many patients fear that they are having a stroke. One of the most concerning calls we receive is from patients who have sudden vision loss. It is up to a well-educated and well-trained staff to triage those calls. Receiving phone calls from scared patients happens daily. ![]()
