Eye Redness: Causes, Symptoms, and Remedies

Subconjunctival hemorrhage

Hello doctor, I have some spots on the sclera of my eyes, and occasionally there are slight blood vessels.
This started at the beginning of this month.
In the lower part of the sclera of my right eye, there has been a significant amount of blood vessels appearing, which lasts for about two days before disappearing (this has happened around three times).
However, the day before yesterday, that area appeared again, but this time it looked like a large pool of blood.
On the first day, it was in the lower area, and the next morning, almost the entire sclera of my right eye was red.
My vision is unaffected, but I do experience some fatigue and occasional tightness, with no other discomfort.
I do not have diabetes, but my liver function is not very good.
Due to my work, I have to face the computer for long periods.
What could this situation be? Are there any medications available at the pharmacy? Or is there anything I should pay attention to in my daily life? Thank you.
^^

Based on your description, it seems to be what is known as "subconjunctival hemorrhage." In addition to environmental factors (such as dry and cold conditions), individual predispositions (like dry eye syndrome or allergies) can also contribute to its occurrence.
If this phenomenon happens frequently, it is important to check for underlying health issues such as hypertension or diabetes, and sometimes a consultation with an internist may be necessary.
In daily life, try to avoid staying up late and prolonged near-vision activities.
You are welcome to visit the outpatient clinic for a detailed examination.
Thank you.

More Info

Eye redness can be a concerning symptom, and understanding its causes, symptoms, and remedies is essential for maintaining eye health. Based on your description, it seems you are experiencing recurrent episodes of redness in the sclera (the white part of the eye), particularly with the appearance of blood vessels or blood spots. This condition can be attributed to several factors, and I will elaborate on them below.

Causes of Eye Redness
1. Conjunctival Hyperemia: This is the most common cause of eye redness, where the blood vessels in the conjunctiva (the membrane covering the white part of the eye) become dilated due to irritation or inflammation. This can happen due to prolonged screen time, allergies, or environmental irritants.

2. Subconjunctival Hemorrhage: This occurs when a small blood vessel breaks beneath the conjunctiva, leading to a bright red patch on the white of the eye. It can happen spontaneously or due to straining, coughing, or trauma. While it looks alarming, it usually resolves on its own without treatment.

3. Dry Eye Syndrome: Prolonged exposure to screens can lead to reduced blinking, resulting in dry eyes. This can cause redness, discomfort, and a feeling of fatigue in the eyes.

4. Allergic Reactions: Allergies to pollen, dust, or pet dander can cause redness and irritation in the eyes, often accompanied by itching and tearing.

5. Infections or Inflammation: Conditions such as conjunctivitis (pink eye) or uveitis can cause significant redness and may require medical treatment.

Symptoms to Monitor
While you mentioned that your vision remains unaffected and you experience only mild fatigue and a feeling of tightness, it is essential to monitor for any additional symptoms, such as:
- Increased pain or discomfort
- Changes in vision (blurriness, light sensitivity)
- Discharge from the eye
- Swelling around the eye

Remedies and Lifestyle Adjustments
1. Artificial Tears: Over-the-counter lubricating eye drops can help alleviate dryness and irritation. They are safe to use and can provide relief from symptoms associated with prolonged screen time.

2. Screen Time Management: Implement the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. This helps reduce eye strain.

3. Proper Lighting: Ensure that your workspace is well-lit to reduce glare on your computer screen, which can contribute to eye fatigue.

4. Allergy Management: If you suspect allergies, consider using antihistamine eye drops or oral antihistamines after consulting with a healthcare provider.

5. Regular Eye Exams: Given your history of liver function issues and prolonged computer use, regular check-ups with an eye care professional are crucial. They can assess your eye health and recommend appropriate treatments.

6. Healthy Lifestyle: Staying hydrated, maintaining a balanced diet rich in omega-3 fatty acids, and getting adequate sleep can support overall eye health.

When to Seek Medical Attention
If the redness persists, worsens, or is accompanied by other concerning symptoms, it is advisable to seek medical attention. An eye care professional can perform a thorough examination to rule out any underlying conditions that may require treatment.

In summary, while your symptoms may be benign, it is essential to take proactive steps in managing your eye health, especially given your work environment and existing health conditions. Over-the-counter remedies can provide temporary relief, but ongoing issues warrant a professional evaluation to ensure your eyes remain healthy.
