Subconjunctival Hemorrhage: Causes and Treatment Options - Ophthalmology

More Info

---

Subconjunctival hemorrhage, commonly known as "red eye," occurs when small blood vessels in the conjunctiva (the clear membrane covering the white part of the eye) break, leading to bleeding under the conjunctiva. This condition can be alarming, especially when it causes noticeable redness in the eye, but it is often harmless and resolves on its own without treatment.


Causes of Subconjunctival Hemorrhage
There are several potential causes for subconjunctival hemorrhage, including:
1. Trauma: A direct injury to the eye can cause blood vessels to rupture.

2. Increased Pressure: Activities that increase pressure in the blood vessels, such as heavy lifting, straining during bowel movements, or even violent coughing or sneezing, can lead to this condition.

3. Medical Conditions: Certain medical conditions, such as hypertension (high blood pressure) or blood clotting disorders, can predispose individuals to subconjunctival hemorrhage.

4. Medications: Blood thinners (anticoagulants) can increase the risk of bleeding, including in the eye.

5. Dry Eyes: As you mentioned, you have dry eye syndrome, which can contribute to irritation and potential bleeding.


Treatment Options
In most cases, treatment for subconjunctival hemorrhage is not necessary, as the condition typically resolves on its own within one to two weeks. However, here are some management strategies:
1. Artificial Tears: Using lubricating eye drops can help alleviate discomfort associated with dry eyes and promote healing.

2. Cold Compress: Applying a cold compress can help reduce any swelling or discomfort.

3. Avoid Contact Lenses: It is advisable to avoid wearing contact lenses until the redness resolves completely, as they can exacerbate irritation.

4. Monitor Symptoms: Keep an eye on any changes in your symptoms. If the redness persists, worsens, or is accompanied by pain, vision changes, or discharge, it is essential to seek further medical evaluation.


When to Seek Further Medical Attention
If you notice that the redness returns after a period of improvement, it may be worth consulting with an eye care professional. While subconjunctival hemorrhage is usually benign, recurrent episodes could indicate an underlying issue that needs to be addressed. Additionally, if you experience any of the following, you should seek immediate medical attention:
- Significant pain in the eye
- Changes in vision (blurriness, loss of vision)
- Persistent redness that does not improve
- Discharge from the eye

Considerations for Your Situation
Given that you are currently studying abroad and have experienced a recurrence of redness after wearing contact lenses, it may be wise to consult with a local eye care professional for a thorough examination. They can assess whether the redness is indeed due to subconjunctival hemorrhage or if there is another underlying issue, such as an infection or exacerbation of dry eye syndrome.

If you are considering returning to Taiwan for medical care, ensure that you have a clear understanding of your symptoms and any treatments you have received so far. This information will be helpful for the healthcare providers in Taiwan to make informed decisions about your care.

In summary, while subconjunctival hemorrhage is often harmless, it is essential to monitor your symptoms and seek medical advice if you have concerns. Your eye health is important, and addressing any issues promptly can help prevent complications.
