What causes blood spots behind the eyes?
Blood spots behind the eyes, also known as subconjunctival hemorrhages, are a common occurrence that can cause concern for many individuals. These spots appear as red or purple patches on the white part of the eye, known as the sclera. While they can be alarming, it’s important to understand the various causes behind these blood spots and when to seek medical attention.
Causes of Blood Spots Behind the Eyes
1. Trauma: One of the most common causes of blood spots behind the eyes is trauma. This can include being hit in the eye, rubbing the eye too hard, or even a minor injury to the face or head. The force of the trauma can cause blood vessels in the eye to burst, leading to the formation of blood spots.
2. Straining or Eye Strain: Straining the eyes, such as during prolonged reading, screen time, or heavy lifting, can also cause blood spots. This is often due to increased pressure within the eye, which can lead to the bursting of blood vessels.
3. High Blood Pressure: Individuals with high blood pressure are at a higher risk of developing blood spots behind the eyes. The increased pressure in the blood vessels can cause them to burst, leading to the formation of blood spots.
4. Vitamin Deficiencies: Deficiencies in vitamins, particularly vitamin K, can lead to blood spots behind the eyes. Vitamin K is essential for blood clotting, and a deficiency can weaken the blood vessels, making them more prone to bursting.
5. Allergies: Allergies, such as hay fever or pollen allergies, can cause blood spots behind the eyes. The inflammation and irritation caused by allergies can lead to the bursting of blood vessels.
6. Aging: As we age, the blood vessels in the eyes become more fragile, increasing the risk of blood spots. This is why they are more common in older adults.
7. Other Medical Conditions: Certain medical conditions, such as diabetes, leukemia, and blood disorders, can also increase the risk of blood spots behind the eyes. These conditions can affect the health of the blood vessels, making them more susceptible to bursting.
When to Seek Medical Attention
While most blood spots behind the eyes are harmless and resolve on their own, there are certain situations where medical attention is necessary. If you experience any of the following symptoms along with blood spots, it’s important to seek medical advice:
– Sudden, severe pain in the eye
– Vision changes or loss
– Swelling or redness around the eye
– Light sensitivity
– Nausea or vomiting
In most cases, blood spots behind the eyes are a temporary and non-serious condition. However, understanding the causes and knowing when to seek medical attention can help ensure your eye health remains in good condition.
