What happens when there is blood on your eye?

Blood in the eye, also known as a subconjunctival hemorrhage, occurs when a small blood vessel in the white part of the eye (conjunctiva) bursts and bleeds. This can happen due to a variety of reasons, such as:

- Trauma: A blow to the eye, such as from a sports injury or car accident, can cause blood vessels in the conjunctiva to break.

- Sudden strain:用力,如咳嗽、打喷嚏或举重,也可导致血管破裂.

- Medical conditions: Certain medical conditions, such as high blood pressure, diabetes, and blood clotting disorders, can increase the risk of subconjunctival hemorrhages.

- Medications: Some medications, such as blood thinners and aspirin, can also cause increased risk of bleeding in the eye.

Symptoms of a subconjunctival hemorrhage include:

- A red or purple spot on the white part of the eye.

- Blurred vision.

- Eye pain.

- Swelling or itching of the eye.

In most cases, subconjunctival hemorrhages are not serious and will resolve on their own within a few weeks. However, it's important to see a doctor if you experience any of these症状.

Treatment for a subconjunctival hemorrhage typically involves:

- Cold compresses: Applying cold compresses to the eye can help to reduce swelling and pain.

- Artificial tears: Artificial tears can help to keep the eye moist and prevent irritation.

- Pain relievers: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help to relieve pain.

In some cases, surgery may be necessary to remove the blood if it does not resolve on its own.

Prevention of subconjunctival hemorrhages:

- Use caution when participating in sports or activities that carry a risk of eye injury.

- Wear protective eyewear, such as goggles or safety glasses, when working with tools or chemicals.

- Control your blood pressure and diabetes if you have these conditions.

- Talk to your doctor about your risk of subconjunctival hemorrhages if you are taking blood thinners or aspirin.
