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.

What Can Cause Kaleidoscope Vision

The most common cause of kaleidoscope vision is an ocular migraine, which is a migraine accompanied by visual symptoms. About 20% of people who suffer from migraines experience some type of aura, also known as a sensory disturbance. Other forms of auras include tingling in the hands or face, muscle weakness, and difficulty speaking.

Migraine Triggers: Eye Conditions That Are Responsible For Blurred Vision And Migraines

Dizziness Nausea Headache Blurred Vision
  • Improper focusing or improper alignment of the eyes causes eye strain. Eye conditions such as farsighted, nearsighted or
  • cause vision changes that are responsible for eye strain.
  • Migraine due to eye strain starts after using your eyes for a long time to do a variety of tasks. Activities such as reading, looking at the computer for long periods and sewing can trigger a migraine.

    If you indulge in activities that require you to use your eyes for long periods of time, make sure you get prescription glasses. The eye strain will reduce and also your migraine.

  • Inflammation of your eyes
  • Eye inflammation may cause blurry vision and migraine. Other symptoms of eye inflammation may include as follows:

  • Swelling and redness of the eyes and eyelids
  • Eye pain when you move your eyes
  • Extreme sensitivity to light
  • It is important to visit an ophthalmologist to examine your inflamed eyes. The eye doctor may use the slit lamp method to see if there is evidence of tumor inside or behind the eye.

    If a tumor is present behind the eye, it is usually accompanied with a lot of eye pain as it will cause the eyes to bulge out. A tumor in the eye can also cause loss of vision or defect in the peripheral vision.

  • Glaucoma attack
  • Most people suffer from open angle glaucoma, which is usually painless. However, an angle closure glaucoma can be painful.

  • Optic nerve conditions
  • Temporary visual loss, lasting for a few seconds

    What Is Visual Disturbance

    Visual disturbance is when you experience a short spell of flashing or shimmering of light in your sight. The symptoms normally last around twenty minutes before your sight returns to normal. Usually, there is no headache during the visual disturbance. A visual disturbance should not be confused with a retinal or ocular migraine where there is a partial or total loss of vision in one eye, normally with a headache.

    Are There Different Types Of Migraine Attacks

    There are several other types of migraine that involve neurological symptoms besides pain, such as:

    • Migraine with brain stem aura. A rare type of migraine in which aura symptoms originate in the brain stem. Symptoms can include vertigo, ringing in the ears, and speech problems.
    • Hemiplegic migraine. A migraine that occurs with an aura that includes one-sided weakness as well as numbness and tingling. It can occur with or without migraine pain.
    • Vestibular migraine. A condition that includes sudden onset of vertigo, disorientation, and balance issues. Many people who experience vestibular migraine have no history of headaches.
    • Retinal migraine. A type of migraine in which the aura causes you to lose vision in one eye.

    You may also be diagnosed with chronic migraine if you experience migraine symptoms that occur 15 or more days in a month.

    What Are The Visual Changes Of Migraine

    Changes in sight usually occur in both eyes, but sometimes in only part of the visual field.1 There are three general types of visual changes with migraine:1

    • Positive symptoms: This describes seeing something that is not really there, like shimmery zig-zag lines, sparkles, dots, or flashes.
    • Negative symptoms: This describes blind spots or tunnel vision.
    • Distorted or altered visual symptoms: This describes a sense of looking through water or colorful, cracked glass. Objects may appear too big or too small.

    Ocular migraine is a medical term for a migraine that includes visual distortions.2 Ocular means connected to the eye. An ocular migraine may be classed as migraine with aura or retinal migraine. In retinal migraine, changes in vision only happen in 1 eye before or during the painful part of a migraine attack.2

    What Are The Symptoms Of An Ocular Migraine

    Blurry vision, brain fog, and increased ocular pressure, due to Intracranial Hypertension

    The most common ocular migraine symptom is a small blind spot that impairs your central vision in one eye.

    This blind spot expands, making it difficult to drive safely or read using the affected eye.

    In addition to the flickering blind spot, other migraine symptoms include:

    • A colorful light ring that is wavy or zigzag and surrounds a central blind spot
    • A blind spot that slowly migrates across your field of vision
    • A migraine lasting between 4 and 42 hours
    • Nausea and vomiting
    • A headache that feels worse when you move your head

    If you have blind spots or other visual symptoms and arent sure whether its an ocular migraine or a visual migraine, cover one eye at a time and observe your sense of sight. If the visual disturbance affects one eye only, it is most likely an ocular migraine.

    What Causes An Ocular Migraine

    It is difficult to pinpoint the exact cause of ocular migraines, but research suggests that structural abnormalities of the visual cortex could play a role.

    Another possible trigger of ocular migraines is visual dysfunction. There are several types of visual dysfunction that can trigger migraines, but a common one is binocular visual dysfunction . A binocular vision problem refers to a misalignment of the eyes.

    Ordinarily, our brain receives an image from each eye and unifies those images to make one clear picture. This can only occur efficiently when the eyes are properly aligned. With BVD, the eyes and brain struggle to form a clear and unified image, which can cause the eyes to become overworked and strained. This high amount of ocular stress can produce painful physical symptoms, like a migraine with aura.

    Reducing the amount of stress your eyes endure can lessen the frequency or intensity of migraines, visual auras, and their debilitating symptoms.

    Why Is My Vision Blurry Here Are 6 Possible Reasons

    According to most sources, blurry, unclear vision is the most common eyesight problem in children and adults. Sudden changes in eye sight can be alarming. Luckily, its usually nothing to worry about. Though, that isnt to say that it cant cause some concern. In this blog post we talk about the major causes of blurry vision. If you or someone you love is worried about their blurred vision, hopefully this can provide some helpful answers!

    1. You might need glasses, or you might need a new prescription.

    Sometimes the curve of the eye disturbs the angle at which light hits the retina, and this produces a blurry picture. We call this issue myopia, or nearsightedness. It can also be a sign of hyperopia, or farsightedness. Astigmatisms are another common refractive error. These conditions can be remedied with corrective glasses or contacts, or an update to your prescription. For some people, LASIK surgery also proves to be a good solution.

    2. You might have conjunctivitis.

    3. You might have presbyopia.

    4. You might have slept with your contacts in.

    Contact lenses move across the eye with every blink, creating tiny scratches. Normally the body has no issue immediately repairing these microscratches, but with your eyes rapid movement while dreaming and the extended period of the contacts being in, the damage can be enough to allow microorganisms in and get into the scratches, causing infection.

    5. You might be developing cataracts.

A person experiencing kaleidoscope vision may perceive their visual field to be fractured, vividly colored, or scrambled similar to looking through a kaleidoscope.

    Visual symptoms like kaleidoscope vision can affect one or both eyes and can occur with or without a headache. In many cases, visual auras precede headaches and migraines.

    Episodes of kaleidoscope vision usually last between 10-30 minutes, but can persist up to an hour.

    What Are Ocular Migraines

    An ocular migraine can cause vision loss or blindness for a short time — less than an hour. This happens before or along with a migraine headache.

    It’s rare. Some research suggests that in many cases, the symptoms are due to other problems.

    Other migraine attacks can also cause vision problems. An aura migraine can involve flashing lights and blind spots. These symptoms usually happen in both eyes.

    Can Poor Eyesight Trigger Migraines

    Headache Eyes Hurt

    Poor eyesight is not commonly a trigger for migraine. Although it can cause eyestrain and headaches in some people. Poor eyesight isnt even in the top 10 most common causes of headaches!

    Refractive errors, like astigmatism, myopia, hyperopia or presbyopia when uncorrected or under corrected can cause muscle tension. If you squint to see better, you are tensing the muscles in your forehead and around your eyes. Or you may find you lean closer to your computer screen, or lift your chin to try and see through the bottom of your spectacles. These changes to posture and muscle tension around the head, neck and shoulders is a very common cause of headaches. So, having up to date and properly fitting spectacles can actually reduce your muscle tension.

    Despite this, when looking for the underlying cause of your headaches or migraines, having a full and thorough eye examination is still high on the list of priorities. Refractive errors may not be a common cause of headache or migraine, but they can contribute to the frequency and intensity of the head pain. There are also other eye related conditions that can cause visual disturbances or headaches such as Angle Closure Glaucoma and Age Related Macular Degeneration.

    If you experience migraine headaches, we recommend consulting your doctor and/or eye care professional. They can help you get to the cause and come up with a treatment plan.
