Subconjunctival hemorrhage is a bright red patch appearing in the white of the eye. This condition is one of several disorders called red eye.
The white of the eye (sclera) is covered with a thin layer of clear tissue called the bulbar conjunctiva. A subconjunctival hemorrhage occurs when a small blood vessel breaks open and bleeds within the conjunctiva. The blood is often very visible, but since it is confined within the conjunctiva, it does not move and cannot be wiped away. The problem may occur without injury. It is often first noticed when you wake up and look in a mirror.
Some things that may cause a subconjunctival hemorrhage include:
A subconjunctival hemorrhage is common in newborn infants. In this case, the condition is thought to be caused by the pressure changes across the infant's body during childbirth.
A bright red patch appears on the white of the eye. The patch does not cause pain and there is no discharge from the eye. Vision does not change.
No treatment is needed. You should have your blood pressure checked regularly.
