Sub Conjunctival Hemorrhage
A subconjunctival hemorrhage is a bleed underneath the conjunctiva- the transparent layer which lies over the white of the eye (the sclera). This bleeding is caused by the leaking of a blood vessel in the conjunctiva.
Causes
Subconjunctival hemorrhages are very common because the blood vessels in the conjunctiva are very fragile and can easily bleed a little. In most cases, there is no specific cause but the following are associated with the condition:
- Strenuous activities
- Coughing and sneezing
- Vomiting
- High blood pressure and taking blood-thinning medications such as aspirin or warfarin
- Other potential causes include injury to the eye or rubbing the eye forcefully.
- A subconjunctival hemorrhage can also happen following an eye operation.
Treatment
This condition usually does not require any treatment and will settle by itself within a week or two. If your eye is uncomfortable, lubricating eye drops may be recommended.
