What is a subconjunctival hemorrhage?

A subconjunctival hemorrhage is when blood collects under the conjunctiva in your eye. The conjunctiva is the clear lining that covers the white part of your eye. The blood comes from broken blood vessels under the conjunctiva.

What causes a subconjunctival hemorrhage?

The exact cause of your subconjunctival hemorrhage may not be known. The following are common causes:

  • An accident or injury to the eye
  • Hard coughs or sneezes
  • Medical conditions, such as high blood pressure, diabetes, or a bleeding disorder
  • Strain, such as when you lift a heavy object or have a bowel movement
  • Blood thinning medicines
  • Vomiting

What are the signs and symptoms of a subconjunctival hemorrhage?

The most common sign is a red patch on the white part of your eye. The redness may be present for 2 to 3 weeks. You may have mild pain when you move your eye.

How is a subconjunctival hemorrhage diagnosed?

Your healthcare provider will examine your eye and check your vision. You may need tests to check for an underlying medical condition.

How is a subconjunctival hemorrhage treated?

A subconjunctival hemorrhage usually goes away on its own. You may need any of the following to help manage your symptoms:

  • Cold or warm compress: Use a cold pack during the first 24 hours. Ask how often to apply it and for how long each time. After the first 24 hours, apply a warm pack on your eye. Do this 3 times each day for about 10 to 15 minutes each time.
  • Eyedrops: You may need artificial tears to keep your eye moist. Use the drops as directed.
