Broken Blood Vessels in Eyes Symptoms

Broken blood vessels in the eyes (subconjunctival hemorrhages) refer to tiny blood vessel breaking beneath the clear surface of your eye (conjunctiva). The condition, commonly referred to as "red eye," may appear alarming, but it's usually a harmless and painless condition that goes away on its own. You may even be unaware that you have a subconjunctival hemorrhage until you look in the mirror.

Causes

• The cause of subconjunctival hemorrhage is generally unknown. However, the Mayo Clinic says forceful actions such as aggressive coughing, vigorous sneezing and even exertion from vomiting may cause a small blood vessel to break in your eye.

Who's at Risk?

• Anyone can experience a broken blood vessel in the eye, but those who take blood thinners or have high blood pressure may be more prone to a subconjunctival hemorrhage. The National Institutes of Health says newborn infants are also vulnerable to the condition as a result of the demanding pressure changes that take place across an infant's body during childbirth.

Symptoms

• A subconjunctival hemorrhage appears as a bright red patch on the white (sclera) of the eye. Although the eye may appear irritated and sore, the patch is painless and will not exude any discharge. The only discomfort may be a slightly rough feeling on the surface of the eye, but it does not impair vision.

Diagnosis

• Contact your doctor if you notice a bright red patch on your eye to rule out a more serious problem. The NIH says your doctor will look at your eyes and conduct a physical examination, including checking your blood pressure. Additional tests may be necessary if you are experiencing other areas of bleeding or bruising.

Treatment

• A subconjunctival hemorrhage does not require any special treatment. You can use eye drops to relieve the scratchy feeling in your eye but otherwise must wait for the blood in your eye to absorb, which typically takes between one and two weeks.
