Causes of retinal migraine Retinal migraine is caused by the blood vessels to the eye suddenly narrowing (constricting), reducing the bloodflow to the eye. It may be triggered by: stress. smoking.
Retinal migraines are thought to happen when the blood vessels in your eye suddenly narrow, restricting the blood flow. Things that can cause them include: stress. caffeine and alcohol.
If you have visual symptoms that have not previously been evaluated by a health care provider, you should see a provider if you have any of the following: Visual changes in only one eye. Visual changes that last less than five minutes and more than 60 minutes. Visual changes without a headache.
Episodes of migrainous visual symptoms in mid or late life are not rare and occur in 1.33% of women and 1.08% of men. These episodes may occur for the first time after age 50 years, in the absence of headache, and a history of recurrent headaches may not be present.
Ocular migraines and stroke are two conditions that share similar symptoms and can often be confused. Although an ocular migraine alone does not indicate a stroke, studies show that those who suffer from ocular migraines may be at a higher risk of experiencing a stroke.
Usually, brain tumor headaches are described as headaches with features more similar to ten- sion-type headaches than to migraines. therefore, it is strongly suggestive that the mechanism of spreading depression can initiate the symptoms of visual aura even in occipital brain tumors.
Retinal migraines are more likely to be triggered by other factors: intense exercise, dehydration, low blood sugar, high blood pressure, hot temperatures, and tobacco use. Certain foods can trigger both types of visual migraines: Red wine or other alcohol.
Ocular Migraine Treatment
The visual portion of an ocular migraine usually lasts less than 60 minutes, so most people don't need treatment. It's best to stop what you're doing and rest your eyes until your vision goes back to normal. If you have a headache, take a pain reliever that your doctor recommends.
Dehydration. Though often overlooked, dehydration is one of the most common causes of migraine headaches—and thus, of visual and ocular migraines. For some especially migraine-sensitive folks, even mild dehydration can trigger a migraine event.
Stress is a common trigger of migraine headaches, including ocular migraine headaches. Since anxiety causes stress, anxiety is a common cause of migraine headaches, including ocular migraine headaches.
Some options for relief without drugs can include resting your eyes, removing yourself from bright sunlight or other harsh lighting, and taking a break from looking at a screen.
Diagnosing an Ocular Migraine
If you are experiencing any kind of impairment to your vision similar to the symptoms above, it is always important to discuss those with your doctor. A neurologist can help a patient distinguish between whether they are experiencing migraine aura or more serious retinal migraines.
A study found that vitamin D deficiency can trigger migraine-related headaches. Vitamin D is essential for your body to fight inflammation and nerve health. When suddenly you become vitamin D deficient, you become more prone to inflammation and nerve pain that influence the development and progression of migraine.
Ocular migraine usually isn't dangerous, but frequent episodes can disrupt your routine. If you experience sudden vision changes with a migraine, it's important to see a healthcare provider. They'll need to make sure it's not a more serious underlying condition causing your symptoms.
A visual migraine is a temporary visual distortion that often begins with a small sparkling, shimmering area that slowly expands outward. The growing spot often has jagged, zig-zag edges. The visual symptoms typically last approximately 20-30 minutes and then completely resolve.
If the vision problem is just in one eye, then it is an ocular migraine. If it is in both eyes, then it is a visual migraine. The most common symptom associated with ocular migraines is a gradual appearance of a blind spot that affects your field of vision.
LACK OF SLEEP
Sleep disturbance is one of the most common factors linked to ocular migraine. Excessive sleep is a less common trigger as well. Sudden changes in your sleep schedule, jet lags, and insomnia can also cause migraines.
A retinal migraine a rare phenomenon that usually affects monocular vision transiently. Duration of symptoms on average is 5 to 20 minutes. The prognosis for an ocular migraine is good. The frequency and intensity of the headache typically decrease.
For migraine relief, the most important pressure point to know to relieve headache pain is the space between the base of your thumb and your index finger. For those who want to be acupressure experts, it's called LI-4 (a.k.a. Hegu).
To deal with head pain and other symptoms that follow the visual disturbances of retinal migraine, you can turn to pain relievers, including Tylenol (acetaminophen) and non-steroidal anti-inflammatory drugs (NSAIDs) such as Advil (ibuprofen).
Some experts think that during a migraine with a visual aura, blood flow to one small area of the brain declines for a while, which can lead to inflammation in blood vessels. Other doctors think the same genes that make people likely to get migraines also raise their chances of heart disease.
Some people get retinal migraine every few months, although the frequency can vary. Retinal migraine is a separate condition. It shouldn't be confused with headache-type migraine or migraine with aura, which usually affects the vision of both eyes.
Migraines are a condition suffered by around 39 million people in the United States, and studies suggest that migraines are linked to heart disease; specifically ocular migraines.
