What is a subconjunctival hemorrhage?
A subconjunctival hemorrhage is when one or more spots of blood appear on the white of your eye. The conjunctiva is the thin membrane (tissue) that covers the white of your eye. It helps protect your eye and keep it moist. The conjunctiva has many tiny blood vessels. When these break, blood appears on the white of your eye.
What causes a subconjunctival hemorrhage?
The subconjunctival hemorrhage may appear on its own. The following are also common causes:
- Hard coughs or sneezes, or vomiting
- Strain, such as when you lift a heavy object or have a bowel movement
- An accident or injury to the eye
- Rubbing your eye roughly
- Wearing contact lenses
What other signs or symptoms might I have?
There are usually no other signs or symptoms. You may have mild irritation. A subconjunctival hemorrhage does not affect your vision.
How is a subconjunctival hemorrhage diagnosed?
Your healthcare provider will examine your eye and check your vision. You may need other tests to check for an underlying medical condition.
How is a subconjunctival hemorrhage treated?
The blood spot usually goes away on its own without treatment. This may take a few days or up to 3 weeks depending on how large the spot is. Artificial tears may help decrease mild irritation and keep your eye moist. Use the drops as directed.
The following list of medications are in some way related to or used in the treatment of this condition.
