Blood Spot in the Eye: Subconjunctival Hemorrhage Awareness in Canada

Blood Spot in the Eye: Subconjunctival Hemorrhage Awareness in Canada

A blood spot in the eye is most commonly caused by a subconjunctival hemorrhage, which occurs when a small blood vessel breaks beneath the clear surface of the eye (the conjunctiva). This results in a bright red patch on the white part of the eye.

Although it can look alarming, many cases are harmless and resolve on their own. However, eye redness should always be assessed carefully, especially if it follows an injury or affects vision.

Common Causes

A subconjunctival hemorrhage may occur due to:

• Minor eye trauma or rubbing
• Sudden increases in pressure from coughing, sneezing, or straining
• High blood pressure
• Use of blood-thinning medications
• Eye strain or irritation

In some cases, no clear cause is identified.

Common Signs and Symptoms

Most people experience:

• A painless red patch on the white of the eye
• No change in vision

Less common symptoms that require attention include:

• Eye pain
• Blurred or reduced vision
• Sensation of pressure or fullness in the eye
• Recurrent bleeding or redness

Any vision changes or pain should be evaluated promptly.

First Aid Awareness: What to Do

First aid does not treat eye bleeding, but awareness helps determine when care is needed.

If a blood spot appears in the eye:

• Avoid rubbing the eye
• Monitor for changes in vision or discomfort

Seek medical assessment if:

• The redness follows an eye injury
• Vision is blurred or altered
• Pain or swelling develops
• The condition does not improve over time
• Eye redness occurs repeatedly

Call emergency services if there is sudden vision loss, severe pain, or significant trauma to the eye.
