Subconjunctival hemorrhage
Subconjunctival hemorrhage is a condition characterized by the rupture of small blood vessels in the eye, leading to bleeding underneath the conjunctiva. The conjunctiva is a clear membrane that covers the white part of the eye (the sclera) and the inner surface of the eyelids.
Causes[edit | edit source]
Subconjunctival hemorrhage can occur due to a variety of reasons. Some of the common causes include:
- Physical exertion: Activities that increase pressure in the veins, such as lifting heavy objects, coughing, sneezing, or straining during bowel movements, can cause a subconjunctival hemorrhage.
- Injury: Any trauma to the eye can result in a subconjunctival hemorrhage.
- Medical conditions: Certain medical conditions, such as high blood pressure, diabetes, and blood clotting disorders, can increase the risk of developing a subconjunctival hemorrhage.
- Medications: Some medications, such as blood thinners and non-steroidal anti-inflammatory drugs (NSAIDs), can increase the risk of bleeding, including subconjunctival hemorrhage.
Symptoms[edit | edit source]
The most noticeable symptom of a subconjunctival hemorrhage is a bright red patch on the white part of the eye. Other symptoms may include:
- Mild irritation in the eye
- A feeling of fullness under the lid or a mild sensation of the eye
- No changes in vision
Treatment[edit | edit source]
In most cases, a subconjunctival hemorrhage does not require treatment as it usually heals on its own within two weeks. However, if the hemorrhage is caused by an injury or if it is associated with high blood pressure or a bleeding disorder, treatment for the underlying condition may be necessary.
