Understanding the Causes of a Burst Blood Vessel Eyelid and Eye

A burst blood vessel in the eye, known as a subconjunctival hemorrhage, can be scary. But knowing why it happens can help ease worries. We’ll look into the reasons behind this condition and what makes it happen.
The Mechanics of a Subconjunctival Hemorrhage
A subconjunctival hemorrhage occurs when a small blood vessel breaks under the eye’s clear surface. This is the conjunctiva. The breakage is often due to a sudden increase in pressure, from different causes.
The conjunctiva has many tiny blood vessels that can easily break. When they do, blood spills into the area, causing a red spot or patch. This is what we see with a subconjunctival hemorrhage.
Common Triggers for Popped Vessels
Many actions and conditions can cause a burst blood vessel in the eye. Coughing, sneezing, and heavy lifting are common causes because they increase pressure suddenly. Rubbing your eyes and eye trauma also stress the blood vessels, leading to a burst.
Medical conditions like high blood pressure, diabetes, and bleeding disorders raise the risk. Also, taking blood thinners can make blood vessels more likely to break.
- Coughing and sneezing
- Heavy lifting
- Eye rubbing
- Trauma to the eye
- High blood pressure
- Diabetes
- Bleeding disorders
- Blood thinning medications
