Recurrent Subconjunctival Hemorrhage: Causes and Tests - Ophthalmology

More Info

---

Recurrent subconjunctival hemorrhage, characterized by the sudden appearance of blood in the conjunctiva, can be alarming but is often benign. Understanding its causes and the necessary tests can help in managing this condition effectively.


Causes of Recurrent Subconjunctival Hemorrhage
1. Trauma or Injury: Minor trauma to the eye, such as rubbing or bumping, can lead to bleeding beneath the conjunctiva.

2. Vascular Fragility: Conditions that affect the blood vessels, such as hypertension or diabetes, can make them more prone to rupture. However, since you mentioned you do not have these conditions, this may not apply to you.

3. Blood Disorders: Conditions like thrombocytopenia (low platelet count) or coagulopathy (issues with blood clotting) can lead to increased bleeding tendencies.

4. Medications: Use of anticoagulants or antiplatelet medications can increase the risk of bleeding.

5. Environmental Factors: Dry eyes or irritants can lead to increased eye rubbing, which may contribute to subconjunctival hemorrhage.

6. Systemic Conditions: Conditions such as allergies or infections can cause inflammation and lead to subconjunctival bleeding.


Recommended Tests
Given your recurrent symptoms and the absence of common risk factors like hypertension or diabetes, your doctor may recommend several blood tests to rule out underlying conditions:
1. Complete Blood Count (CBC): This test will help assess your overall health and detect a variety of disorders, including anemia and infections. It will also check your platelet count, which is crucial in evaluating bleeding risks.

2. Coagulation Profile: Tests such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) can help assess your blood's ability to clot properly.

3. Liver Function Tests: Since the liver produces many of the proteins involved in blood clotting, checking liver function can be important if there are concerns about coagulopathy.

4. Thyroid Function Tests: Thyroid disorders can sometimes contribute to vascular issues, so it may be worth checking.

5. Blood Sugar Levels: While you mentioned not having diabetes, a fasting blood sugar test can help rule out any glucose metabolism issues.


Where to Get Tested
You can choose to go to either a general clinic or a larger hospital for these tests. However, if your symptoms are persistent or worsening, it may be beneficial to visit a larger hospital or a specialized eye clinic where they can provide comprehensive care and possibly refer you to a hematologist if necessary.


Conclusion
Recurrent subconjunctival hemorrhage can be distressing, but understanding its potential causes and the appropriate tests can help you manage the condition better. It’s essential to follow up with your healthcare provider, who can guide you through the testing process and interpret the results accurately. If any abnormalities are found in your blood tests, your doctor will discuss the next steps and possible treatments to address the underlying issues. Always keep an open line of communication with your healthcare provider regarding any new symptoms or concerns.
