Blood vessels in the eye can burst during migraines, but it’s rare and usually harmless, often caused by increased pressure or strain.
Understanding the Connection Between Migraines and Eye Blood Vessels
Migraines are more than just headaches—they’re complex neurological events that can affect various parts of the body, including the eyes. Many people experience visual disturbances, such as aura or sensitivity to light, during migraine episodes. But can migraines cause blood vessels to burst in the eye? This question often arises because some migraine sufferers notice sudden redness or spots in their eyes.
Burst blood vessels in the eye, medically known as subconjunctival hemorrhages, occur when tiny capillaries rupture beneath the clear surface of the eye (conjunctiva). This results in a bright red patch appearing on the white of the eye. While it may look alarming, it’s typically painless and harmless.
The relationship between migraines and these ruptures isn’t straightforward. Migraines themselves do not directly cause blood vessels to burst; however, certain factors associated with migraines may increase the risk of such an event. For example, intense straining during a migraine attack—due to vomiting or coughing—can elevate pressure in blood vessels around the eyes, potentially causing them to rupture.
How Migraines Affect Blood Vessels
Migraines involve complex vascular changes in the brain. Initially, blood vessels constrict (vasoconstriction), followed by dilation (vasodilation), which contributes to pain and other symptoms. These vascular shifts primarily affect cerebral vessels but can have systemic effects.
Although cerebral blood vessels are mainly involved, peripheral blood vessels—including those around the eyes—may also react to these changes indirectly. The autonomic nervous system plays a role here by regulating vascular tone throughout the body. During a migraine attack, fluctuations in this system might cause temporary instability in small blood vessels.
Moreover, migraine sufferers sometimes experience increased blood pressure spikes due to stress or pain intensity. Sudden surges in blood pressure can lead to fragile capillaries bursting more easily than usual. This phenomenon explains why some individuals notice red eyes or subconjunctival hemorrhages coinciding with their migraine episodes.
The Role of Physical Strain During Migraines
Vomiting and severe coughing are common symptoms accompanying migraines for many people. Both actions significantly raise intrathoracic pressure and consequently venous pressure in head and neck veins. This sudden increase can cause delicate ocular capillaries to rupture.
This mechanism is similar to how heavy lifting or intense sneezing might cause a burst vessel in the eye. So while migraines don’t directly damage eye vessels, associated symptoms do create conditions conducive for such occurrences.
Symptoms Indicating a Burst Blood Vessel During a Migraine
Identifying whether a burst vessel has occurred during a migraine is important for proper care and peace of mind. Here are common signs:
- Bright red patch: A sharply defined red area on the white part of your eye that does not move with blinking.
- No pain: Usually painless or mild irritation rather than sharp discomfort.
- No vision changes: Blurred vision or vision loss is uncommon unless another underlying condition exists.
- Mild irritation or scratchy sensation: Some people feel slight discomfort but no severe pain.
- No discharge: Unlike infections, there’s no pus or sticky discharge accompanying this redness.
If any vision changes occur or if pain is severe, immediate medical evaluation is necessary since these could indicate more serious issues like retinal detachment or glaucoma.
Differentiating Burst Vessels from Other Eye Conditions
Redness from burst vessels looks distinct compared to other causes like conjunctivitis (pink eye) or uveitis (inflammation inside the eye). Conjunctivitis often includes itchiness, discharge, and swelling along with redness. Uveitis causes deep eye pain and light sensitivity alongside redness.
Subconjunctival hemorrhage appears as a flat red patch without swelling or discharge and typically clears up within two weeks without treatment.
Risk Factors Increasing Likelihood of Eye Vessel Rupture During Migraines
Certain factors make some individuals more prone to experiencing ocular vessel ruptures during migraine attacks:
| Risk Factor | Description | Relation to Migraine |
|---|---|---|
| High Blood Pressure | Elevated arterial pressure stresses small vessels. | Migraine-related stress may spike BP temporarily. |
| Frequent Vomiting/Coughing | Increases venous pressure around eyes. | Migraine nausea often triggers vomiting episodes. |
| Blood Thinners/Anticoagulants | Impair clotting; easier bleeding from minor trauma. | Migraine patients on meds may bleed more easily. |
| Aging & Fragile Capillaries | Blood vessel walls weaken over time. | Migraines persist at any age; older adults at higher risk. |
Understanding these risks helps patients manage symptoms better during migraine attacks and consult healthcare providers about preventive strategies.
Treatment and Care for Burst Blood Vessels During Migraines
A subconjunctival hemorrhage caused by strain during migraines generally requires no specific treatment beyond reassurance and symptomatic care. The red patch usually resolves within one to two weeks without complications.
Here’s what helps:
- Avoid rubbing your eyes: This prevents additional irritation or injury.
- Use artificial tears: Lubricating eye drops relieve dryness or scratchiness.
- Avoid heavy lifting/straining: Reduces risk of further ruptures during recovery.
- Manage migraine symptoms effectively: Controlling nausea/vomiting lowers strain on ocular vessels.
- If pain develops: Consult an ophthalmologist promptly for evaluation.
In rare cases where bleeding is recurrent or accompanied by other symptoms like vision loss, further investigation is warranted to rule out underlying systemic diseases such as hypertension or bleeding disorders.
The Importance of Medical Evaluation During Migraines With Eye Symptoms
While most bursts are harmless, sudden vision changes during migraines should never be ignored. Conditions like retinal artery occlusion or optic neuritis can mimic some migraine visual symptoms but require urgent treatment.
If you notice:
- Sustained blurry vision or blind spots
- Painful red eyes with swelling
- Bursting sensations beyond superficial redness
- Migraine headaches accompanied by neurological deficits (weakness/numbness)
Seek emergency care immediately. Early diagnosis improves outcomes significantly.
The Science Behind Can Migraines Cause Blood Vessels To Burst In The Eye?
Scientific literature provides limited direct evidence linking migraines as a primary cause for ocular blood vessel rupture. However, several studies highlight indirect mechanisms:
- A study published in Cephalalgia noted that increased vascular fragility combined with sudden rises in venous pressure—common during vomiting episodes linked with migraines—can precipitate subconjunctival hemorrhage.
- Research into autonomic dysfunction in migraineurs shows altered control over peripheral vasculature tone that may predispose small capillaries to rupture under stress.
- Case reports describe patients experiencing repeated subconjunctival hemorrhages coinciding temporally with severe migraine attacks involving intense vomiting and coughing spells.
These findings suggest that while migraines themselves don’t directly cause vessel rupture, associated physiological responses play critical roles.
A Closer Look at Vascular Changes During Migraines
Migraines involve neurovascular dysregulation characterized by phases of constriction followed by dilation of cerebral arteries. Neurogenic inflammation also contributes by releasing substances that affect vessel permeability and tone.
This cascade might extend subtle effects systemically:
- Increased fragility of microvessels
- Heightened susceptibility to mechanical stress
- Temporary blood flow alterations affecting ocular circulation
Such factors collectively raise vulnerability but still require additional triggers like physical strain for actual bleeding events.
Taking Preventive Steps if You’re Prone to Eye Vessel Bursts With Migraines
If you’ve noticed burst blood vessels coincide with your migraines before, consider these proactive measures:
- Migraine management: Work with your doctor on effective preventive medications reducing frequency/severity of attacks.
- Nausea control: Use antiemetics early during attacks to minimize vomiting-induced strain.
- Avoid activities increasing venous pressure: Limit heavy lifting/sneezing/coughing when possible during migraines.
- Regular check-ups: Monitor blood pressure closely since hypertension worsens risks significantly.
- Avoid medications thinning blood unnecessarily: Unless prescribed specifically; discuss alternatives if concerned about bleeding risk.
- Lifestyle adjustments: Maintain hydration, balanced diet, adequate sleep—all proven benefits against frequent migraines and vascular health deterioration.
These steps reduce chances not only for ocular hemorrhage but also improve overall quality of life amid recurrent headaches.

Frequently Asked Questions
Can Migraines Cause Blood Vessels To Burst In The Eye?
Migraines themselves do not directly cause blood vessels to burst in the eye. However, intense straining during a migraine, such as vomiting or coughing, can increase pressure in the eye’s blood vessels, potentially causing them to rupture. This is usually harmless and temporary.
Why Do Blood Vessels Burst In The Eye During Migraines?
Burst blood vessels in the eye during migraines often result from increased pressure caused by physical strain like vomiting or coughing. These actions can cause tiny capillaries beneath the eye’s surface to rupture, leading to a bright red patch known as a subconjunctival hemorrhage.
Are Burst Blood Vessels In The Eye Common In Migraine Sufferers?
Burst blood vessels in the eye are rare among migraine sufferers. While migraines affect vascular function, the occurrence of ruptured eye vessels is uncommon and usually related to secondary factors like sudden pressure changes rather than the migraine itself.
Is It Dangerous If Migraines Cause Blood Vessels To Burst In The Eye?
Blood vessels bursting in the eye due to migraines is generally harmless and painless. Although it may look alarming, these ruptures typically resolve on their own without treatment and do not cause lasting damage or vision problems.
How Can I Prevent Blood Vessels From Bursting In The Eye During Migraines?
To reduce the risk of burst blood vessels during migraines, try to minimize physical strain like severe coughing or vomiting. Managing migraine symptoms early and controlling blood pressure spikes may also help prevent increased pressure on delicate eye capillaries.
The Bottom Line – Can Migraines Cause Blood Vessels To Burst In The Eye?
Bursting blood vessels in the eye aren’t a direct consequence of migraines themselves but result from secondary effects linked with migraine symptoms such as vomiting-induced strain or sudden spikes in blood pressure. These fragile capillaries sometimes give way under increased venous pressure triggered by intense physical reactions accompanying severe headaches.
Most cases resolve spontaneously without lasting harm yet warrant attention if accompanied by visual disturbances or persistent pain. Understanding this nuanced connection helps patients remain calm when spotting scary red patches after an attack while encouraging timely medical consultation when necessary.
Effective migraine control combined with attention toward preventing physical strain reduces risks substantially. So yes—the answer is cautiously affirmative: migraines can indirectly cause blood vessels to burst in the eye, primarily through associated physiological stresses rather than direct vascular damage from headache pathology itself.
