What Are the Causes of Busted Blood Vessels in Eyes?

A burst blood vessel in the eye (subconjunctival hemorrhage) typically occurs near the border between the eye white and its clear surface (conjunctiva). There are several potential causes for this condition.

The Facts

• According to Medline Plus, subconjunctival hemorrhages typically appear as painless red patches on the white of the eye. They do not cause any changes in vision, and they usually disappear without treatment.

Potential Causes

• Potential causes of subconjunctival hemorrhage include lifting heavy objects, violent coughing or sneezing, and vomiting. Individuals who take blood thinners, use herbal supplements (such as ginkgo) or have high blood pressure may also be at risk, states Mayo Clinic.

Causes in Infants

• Systemwide pressure changes during childbirth may trigger the development of subconjunctival hemorrhages in newborn infants, offers Medline Plus.

Considerations

• Frequently, the cause of a subconjunctival hemorrhage cannot be determined, according to Mayo Clinic.

Recommendations

• A blood pressure check is called for in anyone with a subconjunctival hemorrhage.
