What's wrong with bleeding eyes?

Subconjunctival hemorrhage was caused by the rupture of small conjunctival blood vessels, and suddenly painless red eyes were found. It is a common disease in ophthalmology clinics, and it is more frequent, especially in the elderly. The incidence rate gradually increases with age.

It is generally believed that the cause of subconjunctival hemorrhage: hypertensive patients lead to vascular sclerosis and increased fragility of blood vessels. When blood vessels are poorly controlled and blood pressure rises, blood vessel walls are likely to rupture and bleed, so close observation and control of blood pressure and blood lipids are required. Especially for patients with repeated bleeding, check blood pressure, and go to the cardiovascular medical department if necessary. Diabetics, patients with high viscosity, easy to form local small blood clots, leading to blood vessel leakage or rupture bleeding. Young people under heavy social pressure and busy work are also prone to subconjunctival bleeding, especially when they wake up in the morning. For people taking oral aspirin and other anticoagulants, when subconjunctival hemorrhage occurs, the coagulation function of the patient should be tested, and if necessary, go to the medical department to evaluate the dosage of anticoagulant.

Other causes: such as eye trauma patients; young patients with contact lenses; dry eye patients, dry superficial conjunctiva, ruptured blood vessels; severe coughing caused increased abdominal pressure and rupture of the conjunctiva; seasonal changes, especially in autumn and winter, dry and cold air, Vascular constriction, causing subconjunctival hemorrhage; in other patients, unexplained conjunctival hemorrhage, etc.

Subconjunctival hemorrhage generally does not require special treatment and is usually absorbed within 2-3 weeks after bleeding. Although some patients with subconjunctival hemorrhage may not find any reason, for patients who can determine the cause, targeted treatment needs to be conducted for the cause.
