Causes eye bleeding?

Eye bleeding is also known as reddening of the eyes and most people are exposed to this condition once or several times in their lives. Eye bleeding may occur due to some habits brought about by the lifestyle. Many reasons such as disturbed sleep, focusing on a screen or a job for a long time, being exposed to high pressure cause this situation. In addition to these, it is a known fact that diseases such as seasonal allergies, eye pressure, dry eyes, eye inflammations, sty and eyelash inflammation cause eye bleeding. As can be seen, many diseases can cause eye bleeding or redness. Although it sometimes disappears spontaneously, in cases where it does not heal, the underlying cause of blood supply should be investigated and treated. Otherwise, serious eye problems are likely to occur. Especially high fever, pain, itching, watering and vision loss accompanying eye bleeding may be caused by the severity of the underlying disease. In such cases, treatments should be performed as soon as possible.


The white part of the eye known as the sclera is covered with a thin, clear tissue called the conjunctiva. This tissue contains small and thin blood vessels. These small and thin blood vessels in the conjunctiva are very sensitive due to their structure and can easily break or burst. As the vessels are damaged for any reason, blood leaks out and settles between the whites of the eyes and the conjunctiva. Depending on the size of the leak, a part of the eye may appear red, as the size of the bleeding increases, some parts of the eye may be partially red. As the severity of this condition increases, it may be possible to develop an outward swelling in some parts of the eye. Damage to a vessel is not necessarily the case in eye bleeding. Excessive blood accumulation in the capillaries and the expansion of the vessels due to this collection also causes eye bleeding. These capillaries, which are not normally visible, become visible with the condensation of blood and reveal a bloody appearance in the eye. Eye bleeding usually does not cause any pain or vision changes and heals spontaneously. In some cases, it may cause itching or burning.

• Redness in the white part of the eye,
• Irritation and itching in the eyes,
• Eye feeling fuller,
• Eye pain
• Bloody appearance in front of the iris, pupil, or both

• Sensitivity to light,
• Feeling of pressure in the eye and eye swelling.

What are the causes of eye bleeding?

The answers to the question of what causes eye bleeding are quite high. In fact, the cause of many bleeding is often unknown. Since the veins in the eyes are very sensitive and fragile, they are quite susceptible to injury. Eye bleeding may occur due to many conditions such as coughing, sneezing, vomiting, lifting heavy loads, blood pressure, wearing contact lenses, and allergic reactions. In fact, some studies have revealed that babies with asthma and pertussis have a higher risk of eye bleeding. Scratching or rubbing very hard eyes during eye itching can cause eye bleeding. In addition, traumas, injuries, or eye injuries also cause eye bleeding. Eye infections caused by herpes virus, abnormal blood vessels on the iris, blood clotting problems, complications after eye surgery and eye cancers are among the other causes of eye bleeding. It is also known that blood thinning drugs such as warfarin, dabigatran, rivaroxaban, heparin, aspirin, ibuprofen may cause eye bleeding. Eye bleeding may also occur due to diabetes, retinal tears, aneurysm, fluid accumulation behind the eye, and some age-related diseases.

What are the types of eye bleeding diseases?

There are several known types of eye bleeding. The most common of these are subconjunctival and hyphema hemorrhages. The most common bleeding type is subconjunctival hemorrhage. In general, it does not cause any harm and disappears spontaneously within a week. Redness in the white part of the eye is the most common symptom. Because the eye is irritated, such blood flow occurs and it manifests itself with the feeling of fullness in the eye. Hyphema is the blood on the iris and pupil. It usually occurs when there is an injury or tear in the iris or pupil. Although it is not a very common type, it can affect vision and is quite painful. If not treated, there is a possibility of permanent vision loss. Apart from the two types, there are vitreous hemorrhage in the eye fluid, subretinal hemorrhage under the retina and submacular hemorrhage under the macula, which is a part of the retina. Since these bleedings are in the deeper layer of the eye, they are not visible when viewed from the outside.

How is the diagnosis of eye bleeding?

Patients should be examined by an ophthalmologist for the diagnosis of eye bleeding. Often, physical examination is sufficient for diagnosis. However, in order to understand why the disease occurred, questions may be asked about the patient’s medical history. First of all, an examination is performed to make sure that there is no other injury to the eye and eye structure. Then, eye pressure is measured and whether the eyes are enlarged or not is determined. Thus, it is ensured that there is no trauma or bleeding in the depths of the eye. In some cases, blood tests are among the diagnostic methods used to determine whether there is a potentially serious bleeding disorder. In cases considered to be serious, an ultrasound scan can be performed to view the back of the eye. Visual acuity test can be applied to measure the eyesight. In patients of African descent, screening for sickle cell disease or thalassemia is among the diagnostic methods.


What are the treatment methods for eye bleeding?

The answer to the question of how eye bleeding goes depends on the underlying cause of the disease. Most patients’ eye bleeding improves spontaneously within a week. However, if there is an underlying cause other than this, treatment should be applied accordingly. For example, if eye bleeding occurs due to high blood pressure, high blood pressure should be treated. The medications required for this are prescribed by the doctor. Apart from this, more serious eye bleeding should be directly intervened. Eye drops may be recommended for treatment. Tear drops for dry eyes, steroid eye drops for swelling, pain relief eye drops for pain, antibiotic eye drops for bacterial infections, antiviral eye drops for viral infections may be prescribed to the patient. If serious injuries are detected in the blood vessels in the patient’s eye, laser surgery can be applied to treat it. Often, eye surgery is performed to drain the excess blood. Lacrimal duct surgery is also among the treatment methods applied. In order to protect the eye after all treatments, patients should use an eye patch for a while. Because an external factor may cause the treatment not to work or may cause the disease to worsen. After the treatment, it is important to comply with all the conditions specified by the doctor for the healing of eye bleeding.


If you also have persistent and recurrent eye bleeding, you should be examined as soon as possible. Because recurrent eye bleeding may be a symptom of a serious underlying disease and reduce your quality of life. To prevent this, you should start your treatments without wasting time.
