Subconjunctival
hemorrhage, also known as subconjunctival hemorrhage, refers to a disease of subconjunctival hematoma on the surface of the eyeball. This condition is usually caused by a broken or injured blood vessel on the surface of the eyeball, but it can also be caused by certain systemic diseases or eye diseases.
Next, the causes, symptoms, diagnosis and treatment of subconjunctival hemorrhage are introduced.
First, the cause of disease
1. Rupture of blood vessels on the surface of the eyeball: This is the most common cause of subconjunctival hemorrhage. When the eyeball is impacted, rubbed or coughed or sneezed violently, the blood vessels on the surface of the eyeball may rupture, causing blood to infiltrate into the subconjunctival hematoma.
2. Hypertension: In patients with long-term hypertension, the blood vessel wall is easily damaged and the risk of blood vessel rupture is higher, so subconjunctival hemorrhage is more likely to occur.
3. Hematological diseases: such as thrombocytopenic purpura, hemophilia and other hematological diseases, the coagulation function of patients is impaired, which can easily lead to vascular rupture and bleeding.
4. Eye diseases, such as glaucoma, high intraocular pressure, eye infection and other diseases, may lead to rupture of blood vessels on the surface of the eyeball, thus causing subconjunctival hemorrhage.
5. Drug factors: Some anticoagulants and antiplatelet drugs may affect blood coagulation function and increase the risk of bleeding.
2. Symptoms The main symptoms of subconjunctival hemorrhage are hematoma on the surface of the eyeball. Hematomas are usually round or oval in shape, bright red or dark red in color, and vary in size. The location of the hematoma is usually below the eyeball, near the limbus. The patient may experience the following symptoms:
1. Vision loss: As the hematoma blocks part of the vision, the patient may suffer from vision loss.
2. Eye pain: Patients may feel pain when they touch the surface of the eyeball.
3. Foreign body sensation: Patients may feel that there is a foreign body on the surface of the eyeball, and the discomfort is strong.
4. Tears: Some patients may have tears, especially in the case of increased intraocular pressure.
3. The diagnosis of subconjunctival hemorrhage mainly depends on the clinical examination of ophthalmologists. Doctors will use slit lamp and other equipment to examine the patient’s eyeball in detail, observe the location, size and color of hematoma, and whether it is accompanied by other eye lesions. In addition, doctors need to know the patient’s medical history, including whether there are systemic diseases such as hypertension, blood system diseases, and whether anticoagulants and other drugs are being used.
4. Treatment of subconjunctival hemorrhage depends mainly on the cause and severity of hemorrhage. Here are some common treatments:
1. Observation and waiting: For mild subconjunctival hemorrhage, there is usually no need for special treatment, just observation and waiting, and the hematoma will absorb itself within 1-2 weeks.
2. Drug therapy: For subconjunctival hemorrhage caused by hypertension and hematological diseases, targeted treatment is needed, such as lowering blood pressure and supplementing platelets.
3. Surgical treatment: For severe subconjunctival hemorrhage, such as affecting vision and increasing intraocular pressure, surgical treatment may be required, such as intraocular injection of anti-angiogenic drugs, vitrectomy, etc.
4. Preventive measure: For high-risk groups such as hypertension and hematological diseases, we should actively control the condition and conduct regular ophthalmic examinations to avoid eye injuries. At the same time, use drugs according to medical supervision and pay attention to drug safety.
In conclusion, subconjunctival hemorrhage is a common ocular disorder with diverse causes and obvious symptoms. Patients should see a doctor in time and receive targeted treatment according to the doctor’s advice. At the same time, we should strengthen daily health care to prevent the occurrence of eye diseases.
