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.
Harsh lighting, long screen time, other visual strain, stress, dehydration, food additives, and other causes all may trigger an ocular migraine, a subtype that focuses in the eye and causes vision changes.
Ocular migraine, or migraine with aura, and stroke are two different conditions. Having an attack doesn't mean you're having a stroke or are about to have one. However, research has shown that people with migraine with aura are at an increased risk of stroke.
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.
Dehydration is one of several triggers that can exacerbate migraine headaches, including migraine variants like the one you are experiencing. Maintaining good hydration should help reduce the frequency of these visual migraines, which are also known as acephalgic migraine.
The most substantial evidence for magnesium's effectiveness is in patients who have or have had aura with their migraine. It is believed magnesium may prevent the wave of brain signaling, called cortical spreading depression, which produces the visual and sensory changes in the common forms of aura.
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.
Magnesium
A lack of magnesium has been linked to headaches and migraines. Comparatively, magnesium supplementation sometimes helps people treat visual disturbances, nausea, vomiting and other migraine symptoms. Research shows magnesium sometimes offers a preventative migraine treatment.
Common migraine “triggers” that can cause a susceptible person to have a migraine or ocular migraine attack include certain foods, such as red wine, alcohol, aged cheeses, caffeine, nitrates (often found in smoked or cured meats, hot dogs, and other processed foods), and chocolate.
Treatments for ocular migraine are best taken at the start of an attack. You can take over-the-counter painkillers such as paracetamol or ibuprofen for pain relief. Soluble painkillers such as aspirin can enter the bloodstream faster and may be a good choice if you're nauseous.
Sleep can also be very helpful during a migraine attack, and may often help stop the attack, particularly in children.
Vitamin B2 Deficiency
The B vitamins help to protect from headaches, according to the National Headache Foundation, but it is B2 (riboflavin) that really stands out and where a deficiency may lead to headaches.
Once the episode begins, try to find a place to relax, close your eyes and sleep if possible. Aspirin and Tylenol will help relieve inflammation in the body (and the brain) and will usually be effective, especially if a headache is present.
The visual disturbances may temporarily interfere with certain daily activities such as reading or driving, but the condition usually is not considered serious. It has been noted, however, that aura may be associated with a small increased risk of stroke (cerebral infarction) in women.
Silent migraine usually causes some of the visual symptoms of migraine but no head pain. Visual symptoms due to ocular migraine can be scary and disabling, but most are short lived. However, the nonvisual symptoms, such as intense pain, may last from several hours to a few days.
But during a migraine, these stimuli feel like an all-out assault. The result: The brain produces an outsize reaction to the trigger, its electrical system (mis)firing on all cylinders. This electrical activity causes a change in blood flow to the brain, which in turn affects the brain's nerves, causing pain.
People with ocular migraines can have a variety of visual symptoms. Typically you will see a small, enlarging blind spot (scotoma) in your central vision with bright, flickering lights (scintillations) or a shimmering zig-zag line (metamorphopsia) inside the blind spot.
People may use the terms ocular migraine and retinal migraine to mean the same thing, but there are some important differences. An ocular migraine generally occurs in both eyes. A retinal migraine is rare and tends to occur in just one eye, when vessels that supply the eye with blood narrow.
TIA appears more abruptly and is usually of shorter duration. Negativity is typical for it, i.e. part of the visual field, speech, eye movement, ability to swallow, sensation or muscle strength disappear without the above mentioned features of migraine.
Visual migraine
Not everyone experiences a headache relating to these symptoms. In rare cases, visual migraine can trigger a seizure. This is called migralepsy and usually causes a person to experience a seizure within 1 hour after noticing migraine symptoms. Read more on visual migraine here.
Retinal migraine is a rare type of migraine characterized by changes in vision that are monocular , or affect only one eye. Usually, these symptoms precede a headache, but not always.
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.
