Recognizing An Ocular Migraine
A migraine aura can often begin before the actual headache or head pain sets in however, it can occur at the same time as well. An ocular migraine typically impacts both eyes simultaneously, though it can affect only one eye and not the other.
Symptoms of a migraine aura can be both positive or negative in nature. Positive symptoms include things that you can see, whereas negative symptoms involve missing portions of vision.
Positive symptoms include:
- Tunnel vision
- Vision loss in one or both eye
Other signs of an ocular migraine, or migraine aura, can include changes or loss of color vision, blurred vision, a kaleidoscope-like fracturing of images, heat waves, distortion in objects , or an appearance of seeing things as if one were looking through water. Numbness or tingling in the hands or feet, nausea, dizziness, sensitivity to light and sound, weakness, and head pain are additional possible effects of an ocular migraine.
The National Headache Foundation publishes that visual auras typically precede an actual headache or migraine by about 20 minutes to an hour, although the symptoms can persist with the headache itself. Visual impairments that accompany an ocular migraine can make it difficult to function normally and do things like drive safely or read.
Should I Worry About Ocular Migraines
A retinal migraine unlike a migraine aura will affect only one eye, not both. But usually, loss of vision in one eye isnt related to migraine. Its generally caused by some other more serious condition. So if you experience visual loss in one eye, be sure to see a doctor right away for prompt treatment.
Treating And Preventing Migraine With Aura Or Retinal Migraine
For infrequent attacks, medications that target symptoms can be effective, from NSAIDs for pain to anti-nausea medications. Preventative therapies including calcium channel blockers, antiepileptic or tricyclic medications. Quitting smoking is recommended and cessation of oral contraceptives may be advised in certain circumstances. 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. As with all types of migraine, try to avoid triggers like stress, dehydration, high altitude, low blood sugar, excessive heat and extensive time spent staring at a screen.
While the symptoms can be disorienting and distressing, they are often short-lived, and almost always reversible. Take some time away from triggers and wait for the symptoms to fade.

Strategies For Coping With Migraines
As anyone who has ever experienced a migraine knows all too well, once that initial wave hits, the migraine symptoms will only progress over the following minutes and hours, if not days. Fortunately, there are many strategies available to help patients cope with these debilitating episodes.
Stress is one of the main causes of many migraines, therefore, attempts to minimize stress and general anxiety are sound initial steps for many individuals. However, relaxation can mean very different things to different individuals, so each migraineur must devise a relaxation regimen based on his or her preferences. Trigger coping mechanisms might involve measures as basic as taking a nap, reading a book, or soaking in a warm bath.
If these preliminary steps have failed to minimize migraine frequency or offer adequate relief for your migraine symptoms, it may be time to discuss options with your doctor. In fact, many individuals who suffer from migraines are prescribed medication to manage their symptoms. If you are prescribed a migraine medication, you should take your prescribed dose at the first sign of a headache.
Kaleidoscope Vision And Anxiety
When kaleidoscope vision is caused by anxiety, being anxious activates the bodys survival mechanism, also called the stress response or the fight or flight response.
The stress response causes many body-wide changes that give the body a boost of energy and resources when danger is detected.
Visit our Stress Response article for more information about how stress hormones affect the body.
Stress responses have a dramatic effect on the nervous system, as well as the bodys sensory organs, including the eyes and visual system.
When stress responses occur infrequently, the body has sufficient time to recover from the many body-wide changes.
When stress responses occur too frequently, however, such as from overly apprehensive behavior, the body can remain in a state of semi stress response readiness. We call this state stress-response hyperstimulation since stress hormones are stimulants.
Hyperstimulation is also often referred to as hyperarousal,HPA axis dysfunction, or nervous system dysregulation.
Hyperstimulation can cause the changes of an active stress response even though a stress response hasnt been activated. Experiencing kaleidoscope vision, and all of the symptoms associated with it is a common symptom of hyperstimulation.
Visit our Hyperstimulation article for more information about the many physiological, psychological, and emotional changes caused by hyperstimulation.

Migraine Aura With Visual Disturbances
Migraine is a neurological condition that often causes severe headaches. Migraines tend to run in families.
A migraine aura is experienced by approximately 25 percent of people with a migraine, either before or at the same time as a migraine episode.
Typically, people with migraines with aura do not experience all of their migraine episodes, only some of them.
An aura is a temporary visual, auditory, motor, or other sensory change. Visual disturbances can be:
Of the people who experience an aura, about 99 percent have at least one visual symptom with some of their auras.
Some people with a history of migraines report worsening migraine episodes during COVID-19. Some people without a history of migraines report having migraine-like headaches.
A 2020 study found that of 47 people with COVID-19 who reported having a headache, 24 people reported having migraine-like headaches, while 40 percent had symptoms of a tension headache.
Before the development of COVID-19, only 12 of the study participants had previously experienced migraine episodes.
According to a June 2020 research report, the most commonly reported neurological symptoms of COVID-19 are headache and loss of smell.
Serious neurological complications such as stroke or seizures have also been reported, although these are not common with COVID-19.
The most common eye symptoms were:
- dry eyes or a foreign body sensation
- Eye pain
Retinal Migraine Occurs In One Eye
Retinal migraine usually occurs in one eye, and there may be an abnormal spread of electrical activity in the retina. The migraine may also be caused by the sudden constriction or blockage behind, or in, an eye. It may occur with, or without, a throbbing headache at the side of the head. The patient may also simultaneously experience sensitivity to light or nausea. The temporary loss or distortion of vision in one eye makes it difficult to conduct close visual work and makes it dangerous to drive. This type of migraine is generally of short duration, an hour or less, and then vision returns to normal. However, some researchers have found that irreversible vision loss is also possible.
Retinal migraine, as defined by the International Headache Society, is actually fairly uncommon. Most cases are diagnosed as ophthalmic migraine.

How Long Does Retinal Migraine Last
The visual effects of a retinal migraine usually last no more than an hour.
Not all retinal migraine attacks come with a headache or nausea, but such symptoms may last longer potentially for more than a day.
Both children and adults of any age can experience retinal migraine. These tend to be more common in the following groups:
- people under 40 years old
- people with a family history of retinal migraine or headaches
- people with a personal history of migraine or headaches
People with certain illnesses that impact the blood vessels and eyes may also be at risk. These illnesses include:

How Long Do Retinal Migraine Headaches Last
The headache phase of a retinal migraine begins during or within 60 minutes of the visual symptoms.
People suspected of having retinal migraine should be carefully assessed by their doctor for an underlying cause. As well, they should be evaluated to make sure that they do not have a different primary headache disorder that can mimic retinal migraine. Other primary headache disorders that mimic retinal migraine include migraine with typical aura.
In retinal migraine the visual symptoms should only be present when looking through one eye. For example if you look through the right eye and close the left eye, you see twinkling lights but when you look through the left eye and close the right eye your vision is normal. In migraine with typical aura, when you alternate which eye you look through the visual disturbance will be seen with either eye but possibly more prominent with one eye or the other. This is because in retinal migraine the vision symptoms are coming from the eye , while in migraine with typical aura the vision symptoms are coming from the brain . The distinction between retinal migraine and migraine with typical aura is important for treatment considerations and counselling regarding future outcomes. Irreversible visual loss may be a complication of retinal migraine but not migraine with typical aura. It is unclear how often permanent vision loss occurs with retinal migraine and there are no identified predictors for this currently.
How Can I Treat Migraines Without Using Medicines
It is very important to remember that many of the most effective preventive treatments for migraines do not require any medications. Frequent aerobic exercise is an excellent example of an effective way to improve headaches. Other strategies may include better sleep habits, stress reduction, massage, yoga, and acupuncture.

Ocular Migraine And Visual Migraine Symptoms
Ocular migraine symptoms generally include a small blind spot that affects your central vision in one eye. This blind spot gets larger, making it impossible for you to drive safely or read with the affected eye.
In some cases, the entire visual field of one eye may be affected. Generally, the episode lasts less than an hour.
Visual migraine symptoms can vary, and may include:
Visual migraines often appear suddenly and may create the sensation of looking through a cracked window. The visual migraine aura usually moves across your field of view and disappears within 30 minutes.
A flickering blind spot in the center or near the center of your field of view
A wavy or zigzag ring of colored light surrounding a central blind spot
A blind spot that slowly migrates across your visual field
The symptoms of a visual migraine typically affect both eyes and last less than 30 minutes. A migraine headache may occur shortly after the symptoms of a visual migraine subside or no headache may occur.
If you’re experiencing a blind spot or other visual disturbance and you’re not sure if it’s an ocular migraine or a visual migraine , cover one eye at a time. If the visual disturbance affects just one eye, it’s probably an ocular migraine. If it affects both eyes, it’s likely a visual migraine.
What Are The ‘red Flags’ That My Visual Symptoms Are Not Due To Migraine
The typical symptoms of a visual migraine are positive, meaning that there is something shimmering or sparkling that is disrupting the vision. Migraines are less likely to cause “negative” symptoms of pure visual darkness. An episode of visual darkness typically requires additional evaluation for other conditions, including a mini-stroke .

Ocular Migraines And Stroke
Henry HoffmanThursday, September 27th, 2018
Today, migraines are considered the most common neurological disorder according to the Journal of Stroke, and, in the United States alone, about30 million people suffer from these debilitating headaches. Research has determined that all migraineurs are at a higher risk of suffering a stroke, and this risk factor is potentiallydoubled or tripled for individuals who suffer from migraines with visual disturbances collectively known as aura.
Unfortunately, migraines with aura exhibit similar symptoms to those associated with certain life-threatening conditions, namelytransient ischemic attacks and strokes. For this reason, many migraineurs may mistake early stroke warning signs for classic migraine symptoms. Telling the difference and recognizing a medical emergency for what it is can be difficult, but isnt impossible.

What Causes A Migraine
Although migraines are extremely common, their exact cause remains unknown. It appears likely that the visual aura relates to a phenomenon called cortical spreading depression which temporarily affects electrical impulses in the brain. The pain of a migraine headache probably relates to spasm or irritability of blood vessels in the brain, which are sensitive to pain . Beyond these hypotheses, however, the exact mechanism that triggers a migraine remains unknown.
It is often possible to identify certain risk factors that increase the chance of having migraines. A positive family history is very common, so the doctor will often ask about headaches in ones parents or siblings. Overall, migraines are more common in women than in men. In addition, a persons hormonal status can affect the pattern of migraines they experience therefore, it is natural for a woman to notice a change in headaches and other migraine symptoms in adolescence or around the time of menopause.
Many individuals can identify specific triggers for their migraines. These triggers include fatigue, skipping a meal, caffeine withdrawal, stress, and certain foods . For many patients with isolated visual migraines, however, the events can be very infrequent and no definite trigger can be determined.
