If you or someone you love experiences visual symptoms during migraine attacks, the term “ocular migraine” may be something you’re familiar with.

The challenge is that “ocular migraine” is used inconsistently. Some sources use it to describe the visual symptoms of migraine with aura, while others use it to refer specifically to retinal migraine, a much rarer condition. This can make researching symptoms confusing and, in some cases, more alarming than necessary.

In this article, we’ll dive deeper into what ocular migraine means and where confusion can arise. We’ll explore the conditions and common visual symptoms it encapsulates and what you can do to manage it.

A note on terminology: “Ocular migraine” is not a formal medical diagnosis. To make things simple, in this article, we’ll use the term to refer generally to migraine with visual symptoms.

What is an ocular migraine?

Ocular migraine is not an official medical diagnosis. It’s a largely patient-coined umbrella term that refers to the visual symptoms of migraine. It’s common to hear it used to describe:

• The visual symptoms of migraine with aura, which include flashing lights, blind spots, or zig-zag patterns in both eyes.

• Retinal migraine, a rare type of migraine that causes visual disturbances in one eye.

While doctors and headache specialists tend to use more specific terms, “ocular migraine” is still commonly used to describe general visual migraine symptoms. This can make it quite confusing to understand.

Migraine with aura

Aura is the second stage of migraine after prodrome. Only 25–30% of people with migraine experience aura as part of their condition.

People who experience migraine with aura can notice symptoms anywhere from 5 to 60 minutes before the headache phase. In some people, aura symptoms continue into the headache phase.

In very rare cases, aura symptoms can occur without a headache at all.

Aura symptoms fall into six categories: visual, sensory, speech and language, motor, brainstem, and retinal symptoms.

Visual symptoms, which prompt people to use the term “ocular migraine,” are by far the most common.

Retinal migraine

Retinal migraine is a rare type of migraine with aura

It causes temporary visual disturbances in one eye, followed by pulsating one-sided head pain within 60 minutes.

In most cases, all visual disruptions resolve after the episode is complete. But, in rare cases, retinal migraine can be associated with permanent vision loss or lasting changes to eyesight.

If you suspect that you or someone you love may be experiencing retinal migraine, speak to your doctor to explore your options. Early diagnosis is the best way to offset the potential risk of long-term vision changes.

Symptoms of ocular migraine

Visual disturbances are the primary symptom of migraine with aura, occurring in 98–99% of cases. Symptoms range in severity, duration, and type from person to person and attack to attack.

Examples include:

• Flashing bright lights
• Foggy or blurred vision
• Zig-zag of jagged lines
• Blind spots
• Black dots
• Flickering lights
• Visual snow
• Tunnel vision

Doctors can generally tell retinal migraine from typical migraine with aura as symptoms only occur in one eye.

Retinal migraine: Possible complications

In very rare cases, retinal migraine can cause damage to blood vessels in the retina. This puts you at risk for potentially serious complications that can permanently impact your vision.

While it’s important to note that retinal migraine is rare and complications are even rarer, it helps to understand the risks. They include:

• Reversible or irreversible central retinal artery occlusion (CRAO): Caused by a loss of vision due to the sudden blockage of the central retinal artery. Also known as an eye stroke.

• Branch retinal artery occlusion (BRAO): Caused by a sudden blockage of smaller branches in the retinal artery. A serious medical emergency.

• Retinal hemorrhages: Cause vision loss due to bleeding in the retina, which can lead to swelling and damage to retinal tissues.

• Dilatation of retinal veins: Causes visual changes and increases your risk of retinal hemorrhage.

• Ischemic optic neuropathy: Causes vision loss due to the sudden loss of blood flow to the optic nerve.

• Vitreous hemorrhage: Causes vision loss due to the sudden leakage of the gel-like substance inside the eye.

• Retinal pigmentary changes: Causes abnormal deposits of pigment on the retina that can cause permanent visual changes.

Important note: If you or someone you love has visual symptoms during migraine episodes and notices vision changes that don’t ease after the attack, seek medical advice urgently.

When to see a doctor about your ocular migraine symptoms

Visual disturbances of any kind can be scary and confusing, especially if you are still figuring out how your migraine episodes typically progress.

Every migraine attack is different, so it can be hard to know what is typical and what might be concerning. As a general guideline, speak to your doctor about your visual symptoms if:

• It’s your first time experiencing them.
• They feel different than your usual symptoms.
• They are lasting longer than usual.
• They don’t completely resolve after your migraine episode.
• You have one-sided muscle weakness, speech changes, or visual changes that concern you.

Diagnosing ocular migraine

You cannot be diagnosed with ocular migraine as it is not a formal medical diagnosis. Instead, your doctor or specialist will assess whether your symptoms are more consistent with migraine with aura, retinal migraine, or another condition affecting the eyes or nervous system.

Diagnosis is usually based on a detailed discussion of your symptoms, including:

• What you saw
• Whether one or both eyes were affected
• How long symptoms lasted
• Whether they were followed by or occurred alongside head pain

In some cases, you may also be referred for neurological or eye examinations to rule out other causes.

Because diagnosis relies heavily on symptom history, keeping a record of your visual symptoms, their duration, and any accompanying migraine symptoms can be extremely helpful.

Treatment options for ocular migraine

There is no cure for ocular migraine symptoms. Instead, treatment primarily focuses on reducing your likelihood of experiencing an episode.

Managing any type of migraine, including ocular migraine, often involves making lifestyle changes and using medications, depending on your medical history.

Lifestyle changes

Triggers are different for everyone, and avoiding them isn’t a foolproof way to prevent migraine attacks.

If you suspect certain factors may be contributing to your episodes, tracking the circumstances surrounding each attack can help you identify patterns over time. For instance, you could monitor sleep, stress levels, hydration, meals, hormonal changes, exercise, weather, or any other factors that occurred before symptoms began.

Medications

Currently, there’s no specific medication to stop visual aura symptoms once they begin. Instead, treatment focuses on reducing the frequency of migraine attacks and managing associated symptoms such as head pain and nausea.

Make sense of your visual migraine symptoms

The term “ocular migraine” covers a range of visual migraine symptoms and conditions, which can make research complicated and confusing.

As you try to understand your symptoms, the best way to supplement your search is to collect data on your own situation and share it with your doctor.

Using the Human Health app makes it easy to log your symptoms daily, including what visual symptoms you had, how long the episode lasted, and what came before or after.

Frequently asked questions

Is ocular migraine the same as migraine with aura?

Ocular migraine is not an officially recognized medical diagnosis. Instead, it’s an umbrella term commonly used to describe migraine-related visual symptoms. Visual symptoms are very common in people who experience auras as part of their migraine episodes.

Can you have an ocular migraine without a headache?

In rare cases, it’s possible to experience visual aura symptoms without head pain. This is known as silent migraine.

Is retinal migraine dangerous?

Retinal migraine is usually temporary, and most people recover fully after an episode. However, because it causes vision changes in one eye, it should always be assessed by a doctor.

In rare cases, retinal migraine can be associated with lasting vision loss, and other serious eye conditions can cause similar symptoms.
