Have you ever looked in the mirror and noticed a bright red patch in the white of your eye?
This condition, known as a subconjunctival hemorrhage, may look alarming, but it’s usually harmless. Here’s what you need to know about it.

What Is a Subconjunctival Hemorrhage?

A subconjunctival hemorrhage occurs when a small blood vessel bursts under the conjunctiva, the thin, clear tissue covering the white of your eye. The blood is trapped beneath this layer, creating a red or bloodshot appearance.

Despite its striking look, it typically doesn’t cause pain, discharge, or vision problems.

Common Causes

Subconjunctival hemorrhages can happen for a variety of reasons, including:

• Sudden pressure changes: Sneezing, coughing, or straining.

• Eye trauma: Rubbing your eye or an accidental bump.

• Underlying health conditions: High blood pressure or blood-thinning medications.

• Spontaneous occurrence: Sometimes, they happen with no identifiable cause.

When to Seek Medical Attention

While most cases resolve on their own within one to two weeks, you should consult an optometrist if:

• The redness is accompanied by pain or vision changes.

• You experience recurrent subconjunctival hemorrhages.

• You have additional symptoms like swelling or discharge.

Preventing Subconjunctival Hemorrhages

To reduce your risk:

• Avoid excessive eye rubbing.

• Manage conditions like high blood pressure.

• Wear protective eyewear during activities that might lead to eye injuries.

Though a subconjunctival hemorrhage might look concerning, it’s typically a cosmetic issue rather than a medical emergency. However, regular eye exams are essential to maintaining overall eye health and catching any underlying issues early.
