Have you ever suddenly lost vision in one eye, felt a black spot in front of your eye, or felt like flashes of light, and had a throbbing headache? You might have been scared. If you have had this experience, it could be due to a condition called `(Ocular Migraine)` or `(Retinal Migraine)`. Let's talk about this in more detail today.
What is this `(Ocular Migraine)`? To put it very simply...
Ocular migraine is a condition in which you experience temporary changes in your vision, affecting only one eye , and are accompanied (or followed by) a throbbing headache. How do these vision changes occur?
- Scotoma: This can feel like something is in front of your eyes, blocking your vision. This is sometimes called an aura.
- Scintillating scotoma: Some people may see a wave-like pattern of light and dark in front of their eyes, or something that shimmers and dances.
- These are temporary: Most of the time, these vision problems get better after a while, and your vision returns to normal.
However, in very rare cases , some people may experience permanent vision problems. Therefore, it is important to seek medical advice if you experience this. The frequency of `(Ocular Migraine)` varies from person to person. However, people who have it usually experience this at least once in their lives. Although it can start as young as 7 years old, most people first experience it in their 20s. The condition peaks around the age of 40.
What is the difference between `(Ocular Migraine)` and `(Migraine with Aura)`?
Now you might be thinking, "So what's the difference between a regular migraine with an `(Aura)' and this one?" That's a very important question.
`(Retinal Migraine)` or `(Ocular Migraine)` is actually a type of `(Migraine Aura)`, which is a warning sign that occurs before a migraine. But the main difference is that in `(Ocular Migraine)`, the vision changes only occur in one of your eyes. The other eye remains normal. But in `(Migraine with Aura)`, these visual changes affect both of your eyes.
Another thing is that the visual symptoms that occur in `(Ocular Migraine)` usually do not last as long as in `(Migraine with Aura)`. Also, in `(Ocular Migraine)` the headache starts behind the affected eye. In other types of migraine, the headache may spread a little more.
How common is this `(Ocular Migraine)`?
Ocular migraine is actually very rare. But it's hard for researchers to say exactly how rare it is, because many people don't report it. In general, about 18% of women and 6.5% of men have migraines. But not everyone who has migraines gets ocular migraine.
What are the symptoms of an Ocular Migraine?
The symptoms of this condition can vary slightly from person to person, but the main ones are visual impairment in only one eye and a throbbing headache.
These may temporarily occur as visible symptoms:
- Dark spots that partially or completely obscure vision.
- Zigzag patterns.
- A flashing or dancing light.
- Floating lines.
These symptoms usually last for about 10 to 20 minutes . After that, your vision gradually returns to normal. Most of the time, these `(Ocular Migraine)` attacks affect only one eye each time.
Headaches can occur before, during, or within an hour of these visual changes. Symptoms of a migraine headache include:
- A moderate to severe headache. It can feel like a throbbing, throbbing, or dull ache. The pain often comes from behind the affected eye.
- Sensitivity to light, noise, and certain smells.
- Nausea and vomiting.
- The food is tasteless.
- Feeling very hot (sweating) or cold (shivering).
- Paleness of the skin (pallor).
- Feeling tired.
How long have you had an `(Ocular Migraine)`?
The visual problems that occur during an `(Ocular Migraine)` can usually last from 5 minutes to 60 minutes (one hour) . However, the headache, if left untreated, can last from 4 hours to 72 hours (3 days). Imagine how difficult that is!
What are the causes of Ocular Migraine?
Researchers still don't know exactly what causes an ocular migraine. But they have some theories. One theory is that it's caused by a problem with the blood vessels that supply blood to your eyes, or the blood flow . This change in blood flow is what causes the vision symptoms. When the blood vessels relax again, blood flows normally and vision returns to normal.
Researchers also believe that there is a genetic influence , as 50% of people who experience this condition have a family history of migraines.
What are the triggers for this `(Ocular Migraine)`?
The triggers for an Ocular Migraine are generally the same as those for a migraine with an Aura. Common triggers include:
- Stress.
- Smoking.
- High blood pressure (Hypertension).
- Birth control pills containing hormones.
- Exercise (for some).
- Bending forward.
- Going to places much higher than sea level.
- Dehydration.
- Low blood sugar levels (Hypoglycemia).
- Hyperthermia.
- Alcohol and caffeine.
If you have something like this, it's very important to be aware of these `(triggers)`.
What are the possible complications of Ocular Migraine?
Most of the time, this is not dangerous. However, very rarely , `(Ocular Migraine)` can cause serious complications related to the blood vessels and blood flow in and around the eye. These include:
- Central retinal artery occlusion (CRAO). This is also called an ``eye stroke`` .
- Branch retinal artery occlusion (BRAO) / retinal infarction.
- Central retinal vein occlusion.
- Retinal hemorrhages. This can cause swelling (edema) of the retina and optic nerve root.
- Ischemia is a condition in which the blood supply to the eye is restricted. This can affect either the choroid or the optic nerve.
- Vitreous hemorrhage.
Important: Some medications can increase the risk of these complications. So if you are taking any medications, starting a new one, or stopping them, be sure to talk to your doctor.
How to diagnose `(Ocular Migraine)`?
If you can see a doctor right away when you have an ocular migraine, they may be able to use an instrument called an ophthalmoscope to look at your eye to see if there is reduced blood flow to it. This can help confirm the condition.
But because these attacks are often short-lived, doctors conclude that this is an ``Ocular Migraine'' based on your symptoms, medical history, and family history.
Your doctor may refer you to an eye specialist (ophthalmologist) to make sure there is no other serious underlying eye disease.
What are the treatments for Ocular Migraine?
If an ocular migraine occurs very infrequently, like once a month, doctors usually do not recommend treatment.
But if you have frequent ocular migraines, the main goal of treatment is to reduce the frequency of these attacks. Treatment options include:
- Avoiding triggers: It is helpful to know what triggers your ocular migraines. Keeping a diary of when and how your migraines occur can help. Lifestyle changes such as making dietary changes, controlling stressors such as high blood pressure, and quitting smoking can help reduce the number of attacks.
- Medication: If lifestyle changes do not help, the next step is to use medications to help prevent the occurrence of `(Ocular Migraine)` (`prophylaxis therapy`). `Calcium channel blockers` (e.g. `nifedipine`, `verapamil`) are the main drugs used for this. `Aspirin` and some `antiepileptic drugs` may also help.
Again, a reminder: All of these medications should be taken only under medical advice. Taking medications at your own discretion will only lead to more problems.
What is the prognosis of Ocular Migraine?
The outlook for ocular migraine is generally good. Although these attacks can cause pain and vision problems, doctors consider them to be a benign condition.
However, as mentioned earlier, very rarely , these attacks can cause permanent vision problems.
How to prevent Ocular Migraine?
You may not always be able to prevent an Ocular Migraine. However, avoiding the triggers that cause it can help. Try to keep a record of what you were doing (activities, what you ate, how you felt, etc.) before you had an Ocular Migraine. It will take some time to figure out what triggers your migraines.
When should you see a doctor about `(Ocular Migraine)`?
If you experience an ocular migraine for the first time in your life , it is important to see a doctor to make sure that this is not due to a more serious eye or brain condition.
If you are already known to have Ocular Migraine, be sure to talk to your doctor if your symptoms change or get worse .
Is an Ocular Migraine a Small Stroke?
No, an Ocular Migraine is not a small stroke. They are two different conditions. However, a stroke can cause vision problems similar to an Ocular Migraine. This is why it is important to seek medical advice if you experience sudden changes in your vision.
Other symptoms of a `(Stroke)` are:
- Weakness or numbness on one side of the body.
- Difficulty or inability to speak (Aphasia).
- Stuttering or slurred speech (Dysarthria).
- Loss of muscle control on one side of the face.
- The sudden partial or complete loss of one or more of the senses of sight, hearing, smell, taste, or touch.
- Loss of balance or difficulty walking (Ataxia).
- Dizziness or Vertigo.
- Nausea and vomiting.
- Stiff neck.
Attention: If you or someone you know has these symptoms, seek medical help immediately!
Although ocular migraines are not usually dangerous, frequent occurrences can interfere with your daily activities. If you experience sudden vision changes along with a migraine, it is important to see a doctor. They can make sure that the symptoms are not caused by a serious underlying condition. They can also advise you on treatment options to better manage your ocular migraines.
