Blood in the Eye: What is it? Symptoms, Subconjunctival Hemorrhage, Causes and Treatment

The white part of the Eye, known as the sclera, is covered by a thin, transparent tissue called the conjunctiva.

Bleeding inside the Eye can cause a small spot of redness or a large area of ​​red Blood. If you have ever experienced bleeding in one or both eyes, the condition can often be alarming.


The bleeding appears as a patch of bright red Blood on the white part of your Eye. While it can be frightening to wake up to what seems to be a bleeding eye, a bleeding look is usually harmless, with Blood visible due to a broken blood vessel.

The conjunctiva covers the inside of your eyelid, which houses a network of small, thin blood vessels.

These tiny blood vessels are pretty fragile and can explode or break easily; when they die, the Blood is filtered and installed between the conjunctiva and the sclera; if the leak is small, a part of your Eye may seem a little red.

It is not a reason to worry too much, but when combined with eye pain, abnormal drainage, or vision problems, this may indicate a severe medical problem.

However, if the leak is large enough, the entire white part of your Eye may appear completely red like Blood and, in some cases, may bulge outward.


You may have bleeding in your Eye if you see a bright red pool of Blood inside your Eye; the condition usually does not cause pain or changes in vision but occasionally causes mild itching in the Eye; sometimes, you may feel an itching sensation when you blink.

Subconjunctival hemorrhage

A subconjunctival hemorrhage is another term for bleeding from the Eye.

The conjunctiva contains many blood vessels and capillaries. These vessels may rupture and cause Blood to leak into the area between the conjunctiva and the Eye’s target.

When this happens, a small amount of blood accumulates under the conjunctiva. This small accumulation of Blood is called a subconjunctival hemorrhage. Minor bleeding under the Eye’s outer membrane causes bright red spots to appear on the white of the Eye.

Subconjunctival hemorrhages usually occur due to minor injury or trauma to the Eye. Even rubbing the Eye too hard can cause bleeding.

The most common causes of subconjunctival hemorrhages are coughing, sneezing, and straining. People who have diabetes, high blood pressure, or take certain medications may also have subconjunctival hemorrhages.

Subconjunctival hemorrhages occur on the surface of the Eye. As they do not affect the cornea or the inside of the Eye, the vision is not affected.

They are not painful and do not cause sensations or real symptoms other than red spots. Although red or Blood in the Eye may appear severe, most subconjunctival hemorrhages are usually harmless and go away on their own in a few days.

Generally, no treatment is necessary, but a doctor may recommend artificial tears if irritated.
