Burst Blood Vessel in the Eye: When to Seek Medical Attention

Daily Health

17/03/2026

A burst blood vessel in the eye, often appearing as a bright red patch on the white of the eye, can be alarming. While frequently harmless and resolving on its own, understanding when it might signal a more serious underlying condition is crucial for maintaining eye health. This article explores the causes, symptoms, and when to consult a healthcare professional.

Key Takeaways

A subconjunctival hemorrhage is usually benign and resolves without treatment.
Risk factors include eye strain, coughing, sneezing, and certain medical conditions.
Seek immediate medical attention if you experience vision changes, pain, or trauma.

Understanding Subconjunctival Hemorrhage

A subconjunctival hemorrhage occurs when a tiny blood vessel breaks under the conjunctiva, the clear membrane covering the white part of the eye. This leads to blood pooling, creating a vivid red spot. It typically doesn't affect vision or cause discomfort, often being discovered incidentally.

Common Causes

Several everyday activities and conditions can contribute to a burst blood vessel in the eye:

Eye Strain: Prolonged reading, computer use, or focusing intensely can increase pressure.
Physical Exertion: Straining during bowel movements, heavy lifting, or intense exercise.
Sudden Pressure Changes: Forceful coughing, sneezing, or vomiting.
Minor Trauma: Rubbing the eyes too vigorously or a slight bump.
Medications: Blood thinners like aspirin or warfarin can increase the risk.
Underlying Medical Conditions: High blood pressure, diabetes, or bleeding disorders can sometimes be a factor.

When to Be Concerned

While most instances of a burst blood vessel are not serious, certain symptoms warrant immediate medical evaluation:

Vision Changes: Blurred vision, double vision, or loss of vision.
Eye Pain: Discomfort or pain in the affected eye.
Recent Trauma: If the hemorrhage occurred after a significant injury to the head or eye.
Recurrent Hemorrhages: Frequent occurrences may indicate an underlying health issue.
Other Symptoms: Such as discharge from the eye, redness spreading beyond the initial spot, or sensitivity to light.

Diagnosis and Treatment

In most cases, a visual examination is sufficient for diagnosis. If there are concerns about underlying causes or associated injuries, a doctor may perform further tests. Subconjunctival hemorrhages typically resolve on their own within one to two weeks, gradually fading in color. Artificial tears can be used for comfort if mild irritation occurs. However, if the cause is determined to be a medical condition, that condition will require appropriate treatment.
