Subconjunctival hemorrhageDefinition: Red eye is a bright red or crimson patch appearing in the white of the eye.
Alternative Names: Red eye
Causes, incidence, and risk factors: Subconjunctival hemorrhages are bright red patches on the white of the eye (bulbar conjunctiva ) that occur when a small blood vessel near the surface breaks open and bleeds. They�may happen without injury, and� are often first noticed when one awakens and looks in the bathroom mirror. Sudden increases in pressure such as violent sneezing or coughing can produce subconjunctival hemorrhages. These hemorrhages�may also occur in people with high blood pressure or in those who take blood thinners. These hemorrhages are common in newborn infants, and they often appear as a bright red sickle-shaped hemorrhage on the white of the eye. They are thought to be caused by the relatively violent pressure changes across the length of the infant's body during delivery.
Symptoms: - A bright red patch appearing on the white of the eye
- Painless and no discharge from eye
Signs and tests: Subconjunctival hemorrhages are diagnosed by direct examination. Blood pressure should be tested. If other areas of bruising or bleeding are present, more specific tests may be needed.
Treatment: No treatment is needed. However, routine blood pressure monitoring is advised.
Expectations (prognosis): Subconjunctival hemorrhages are self-limiting and resolve over a period of one week.
Complications: There are usually no complications.
Calling your health care provider: Call your health care provider if a bright red patch appears on the white of your child's eye. Contact your health care provider if you take blood thinners or have bleeding or bruising in other areas.
