Are Red Spots in the Eye a Sign of High Blood Pressure?

High blood pressure or hypertension is a leading problem in the world and many people suffer from this issue. It is a condition when the force of the blood against the artery walls becomes too high. Since high blood pressure puts huge strain on your organs and leads to an increased risk of heart stroke, heart attack, and kidney disease, one must monitor the blood pressure from time to time and also pay attention to every single symptom that might be associated with high blood pressure. One of the symptoms of high blood pressure could be detected in the eyes. It is believed that red spots on the eye could be a sign of high blood pressure. Let us take a look on this matter as we proceed on with the article further.

Are Red Spots In The Eye A Sign Of High Blood Pressure?

Are Red Spots In The Eye A Sign Of High Blood Pressure?

A red spot on the eye is generally a small blood vessel that gets burst during the night.(1) This is called a subconjunctival hemorrhage. However, can the appearance of red spots in the eye be a sign of high blood pressure?

Might Be A Direct Sign

A red spot on the eye generally appears when blood starts leaking between layers of the eye. This often causes bright red patches on the white part of the eye. According to the American Heart Association, red spots or blood spots in the eyes might be an alarming sign of high blood pressure.(2)  If you notice such red spots or blood spots in your eyes, you should get your eyes checked at the earliest. This is because high blood pressure could be dangerous and if the red spots appear because of hypertension then it can also lead to other complications with vision and overall health.

Might Not Be A Direct Sign

We would also state that high blood pressure itself is a rare cause of red spots in the eye. This might look alarming, but probably it is not as serious as it looks. As mentioned earlier, red spots in the eyes might occur if your blood vessels in the eye have broken and leaked, and this can happen even after sneezing or coughing.

So, coughing, sneezing, and a few other similar actions can cause subconjunctival hemorrhages and this might be because they increase the blood pressure slightly in your veins. This quick rise in blood pressure can cause the capillaries to break.(3)


A red spot in your eye is generally harmless and clears up without treatment. However, it is always better to consult with your doctor if the red spots in the eye remain for more than a few days or if you experience any other symptoms that might be alarming for an increased blood pressure.
