Causes, Symptoms, Management, and Prevention of Burst Eye Blood Vessels image 1

When you sometimes look in the mirror and notice a burst blood vessel in your eye, it is only natural to be surprised. Eye capillaries can burst for various reasons.

When an eye capillary bursts, blood pools beneath the conjunctiva and becomes visible. In many cases, it improves naturally over time.

Let’s look at what causes burst eye blood vessels, how to manage them when an eye capillary bursts, and how to prevent them.

The symptom of a burst eye blood vessel is also called subconjunctival hemorrhage. It refers to a symptom in which blood pools under the conjunctiva due to bleeding from conjunctival blood vessels, making the eye appear red.

This is a symptom in which blood collects under the conjunctiva, similar to a bruise on the skin. Unlike bloodshot eyes, it is caused by burst capillaries spreading across the white part of the eye and turning it red.

A burst eye blood vessel can occur for various reasons, and one possible cause is conjunctivitis.

Conjunctivitis is inflammation of the conjunctiva. It can be broadly divided into infectious conjunctivitis, which is caused by infection from pathogens such as viruses, and allergic conjunctivitis, which occurs as an allergic reaction.

If conjunctivitis develops, symptoms of burst eye blood vessels may occur along with pain, eye discharge, and a foreign-body sensation.

This symptom can also occur due to stress. When stress raises intraocular pressure, eye capillaries may burst.

In addition, external impact can also cause a burst blood vessel in the eye. Rubbing your eyes too hard can put pressure on them and cause eye capillaries to burst.

A similar symptom can occur when wearing contact lenses. In some cases, impact during the process of inserting or removing lenses can cause a burst blood vessel in the eye.

This symptom can also appear when the eyes are dry. When the eyes become dry, friction occurs every time you move your eyes, which can cause weak blood vessels to burst.

As such, burst eye blood vessels can occur for various reasons, so it is important to manage and prevent the symptoms properly.

If an eye capillary bursts, it usually recovers naturally over time, but if you feel discomfort, applying a cold compress may help.

Also, rubbing your eyes can easily cause blood vessels in the eye to burst, so correcting the habit of rubbing your eyes can help prevent the symptom.

If you usually wear contact lenses, it is best to clean and disinfect them regularly so that foreign substances do not get in.

Also, when exercising or doing work or activities that may irritate the eyes, it is best to protect your eyes by wearing protective equipment.
