What causes eye bleeding?
Eye bleeding is most often caused by injury to the eye, such as blunt trauma or penetration of something sharp into the eye. Other causes of eye bleeding include malformations of the blood vessels in the eye, cancer in the eye, or severe inflammation of the inner portions of the eye.
Common causes of subconjunctival hemorrhage
Subconjunctival hemorrhages that appear as red spots on the whites of the eyes may appear for no apparent reason and are typically not a serious problem. Certain factors can cause subconjunctival hemorrhages including:
- Blood thinner medications
- Hypertension (high blood pressure)
- Sneezing or coughing, especially if prolonged or violent
Common causes of hyphema
Eye bleeding may be the result of a variety of causes including:
- Blunt trauma to the eye, such as such as being hit in the eye by a baseball or being injured in a car accident
- Penetrating trauma to the eye, such broken glass or a nail sticking into your eye
Rare causes of eye bleeding
Eye bleeding can also rarely be caused by:
- Cancer of the eye
- Iritis (inflammation of the iris, the colored part of the eye)
Serious or life-threatening causes of eye bleeding
Because any injury to the eye can result in a permanent loss of vision, eye bleeding from any cause should be considered serious until proven otherwise and should be examined immediately by a physician.
Questions for diagnosing the cause of eye bleeding
To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your eye bleeding including:
- When did you first notice blood in your eye?
- Did anything happen that could have caused blood in your eye?
- Is your eye painful?
- Did the bleeding occur suddenly or slowly?
- Do you have any other symptoms?
- Do you notice that your vision is affected?
- Have you noticed any changes in your vision before the eye bleeding began?
- Are you taking any medications?
What are the potential complications of eye bleeding?
Depending on the cause of eye bleeding, complications can vary from almost none to permanent loss of vision. Even scarring of the eye can alter your vision, so it is important to have your eye bleeding examined promptly.
Because eye bleeding can be due to serious injury or disease, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:
- Impaired vision
- Loss of vision and blindness
- Loss of your eye
