Why Does My Vision Go Blurry Before A Migraine

Visual Symptoms Of A Migraine

Why does my vision go blurry before a migraine ? | Protect your health – Health Channel

Kaleidoscope vision is a component of only one type of visual aura. Understanding the other types of visual disturbances that may accompany a migraine can provide more clarity.

The 3 types of visual auras are:

Positive Visual Aura

This is when a person sees something that isnt actually there. For example, a person experiencing a positive aura may see zig-zag or squiggly lines, flashes, stars, or dots. These perceived shapes may be colorful and move around the visual field or grow larger. A visual hallucination is also considered a positive aura.

Negative Visual Aura

This is characterized by any loss of vision during a migraine, whether partial or total. With negative auras, one may experience blind spots, loss of peripheral vision, or a brief period of total vision loss.

Altered Visual Aura

This type of aura distorts what you see without adding or subtracting anything. For example, one may perceive a straight line as wavy or blurred. Kaleidoscope vision is considered an altered aura.

Other forms of altered aura include misperceiving the size of an object , distorted distance perception, and distorted or absence of color.

If you experience any of the above symptoms with a migraine, seek medical attention to rule out more serious conditions, like retinal tearing or stroke.

Can Poor Eyesight Trigger Migraines

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.

What about in children?

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.

Diseases Associated With Blurred Vision

Head injury: Any injury to the head is considered to be a medical emergency and can range from a bump or bruise to a traumatic injury. Head injuries can be open or closed, and treatment will depend on the location and severity of the injury. Concussions can interfere with vision, and damage or swelling near the optical nerves will also cause blurred vision.

Low blood sugar: Hypoglycemia is potentially dangerous, and is common among people with diabetes. While high blood sugar can cause swelling in the eye, low blood sugar causes blurred vision or double vision. This can be avoided by monitoring and controlling blood sugar levels.

Cataracts: This is a condition where the lens of the eye becomes cloudy and occurs with aging. As a result, vision becomes foggy and blurred like looking through a frosted window. Cataract surgery is the best treatment option to restore clear vision.

Macular degeneration: Blurred vision is one of the first symptoms of this eye disease. There is no cure, but there are treatment options such as medications and laser surgery available to help correct vision.

Glaucoma: This is an eye disorder associated with increased pressure inside the eye. The first sign is blurred or double vision, and if left untreated, this can develop into peripheral vision loss and blindness. Glaucoma can be treated with eye drops as well as surgical methods.

Visual Disturbance Of Migraine Is Short

The visual disturbances of migraine generally last less than an hour, most commonly 10-30 minutes. Sometimes they only last seconds. They may or may not be associated with a headache, and some individuals only experience the visual symptoms without headaches. The visual symptoms usually start before the headache but may occur during the headache.

To complicate the issue, migraine may change throughout life. The character of the headache may change, and the visual symptoms may change. The most common pattern is for the headaches to become less severe or even go away, with episodes of visual aura persisting. Some people only experience migraine-related visual symptoms, often without headache, starting at age 50 or later.

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.

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
