Blood in the Eye: Causes and When to Seek Help - Ophthalmology

More Info

---

Experiencing blood in the eye can be concerning, especially when it occurs frequently without any accompanying pain or discomfort. Based on your description, it sounds like you may be dealing with a condition known as subconjunctival hemorrhage, which is characterized by bleeding beneath the conjunctiva (the clear membrane covering the white part of the eye). This condition can lead to the appearance of blood in the eye, often resembling tears, and may cause the eye to feel sticky due to the blood mixing with tears and other secretions.


Possible Causes
1. Trauma or Injury: Even minor trauma that you may not recall can lead to subconjunctival hemorrhage. This can include rubbing your eyes or even a sudden increase in pressure, such as during coughing or sneezing.

2. Vascular Fragility: Some individuals have more fragile blood vessels, which can rupture easily, leading to bleeding. This can be exacerbated by factors such as high blood pressure or certain medical conditions.

3. Blood Disorders: Although you mentioned that your blood tests came back normal, conditions affecting blood clotting or platelet function can lead to recurrent bleeding. It's essential to consider that some disorders may not be immediately apparent in standard tests.

4. Medications: If you are taking any anticoagulant medications or supplements that affect blood clotting, this could increase the likelihood of bleeding.

5. Environmental Factors: Dry air, allergies, or irritants can cause eye strain and lead to increased susceptibility to bleeding.


When to Seek Medical Attention
While subconjunctival hemorrhage is often harmless and resolves on its own, there are specific situations where you should seek medical attention:
- Recurrent Episodes: If you are experiencing this bleeding frequently (as you mentioned, over ten times in the past year), it is advisable to consult a healthcare professional.


- Changes in Vision: If you notice any changes in your vision, such as blurriness or loss of vision, this warrants immediate medical evaluation.

- Pain or Discomfort: Although you currently do not have pain, any new symptoms such as discomfort, redness, or swelling should be evaluated.

- Associated Symptoms: If you experience headaches, dizziness, or other systemic symptoms, these could indicate a more serious underlying condition.


Recommended Specialists
Given your symptoms, it would be best to consult an ophthalmologist, a specialist in eye health. They can perform a thorough examination to determine the cause of the bleeding and rule out any serious conditions. If necessary, they may refer you to a hematologist if there are concerns about blood disorders.


Conclusion
In summary, while subconjunctival hemorrhage is usually benign, the frequency of your episodes and the associated symptoms suggest that further evaluation is warranted. An ophthalmologist will be able to provide you with a comprehensive assessment and appropriate management options. In the meantime, try to avoid any activities that may strain your eyes, such as prolonged screen time without breaks, and ensure that you are protecting your eyes from potential irritants.
