What is a subconjunctive hematoma?
Subconjunctival hematoma is a visible blood collection in the eye, which is the result of a broken blood vessel. Specifically, it occurs in the subconjunctival space along the white eye, under the conjunctiva layer. Most subconjunctive hematomas are painless and do not disturb vision. They usually leave in about two weeks without any special type of care of themselves or medical treatment. Hematoma, which persists for more than two weeks or is often repeated, can be a sign of a basic health problem and should be evaluated by a doctor.
blood vessels in the subconjunctival space are relatively delicate. They can break open and escape blood for many different reasons. Subconjunctive hematoma may occur after strong sneezing, coughing, attacking vomiting or slight eye injury. Sometimes it is enough to wipe the itchy eye to break the blood vessel. Other potential causes and risk factors include high blood pressure, diabetes, anemia and eye surgery.
If subconjunctive hematoma is not caused by eye damage, bude probably completely painless. A bright red spot appears on the white eye and spreads as more blood spills. Since the breaking of the blood vessels is under the outer membrane of the eye, the blood package cannot be rinsed with water or tissue.
Most hematomas grow in the first or two days and slowly shrink in one or two weeks. Stejně jako modřina kůže, subkonjunktivální hematom trvá jen tak dlouho, dokud podkladová tkáň absorbuje veškerou uniklou krev. The place usually becomes a lighter color during the therapeutic phase and changes from bright red to yellow orange. After two weeks, white eyes are usually back to normal.
It is important to see an eye physician if the subconjunctive hematoma is accompanied by visual disorders, pain or bleeding other parts of the body. Medical care is also necessary if hematomas appear in both eyes at a time or if the red spot fails to pdisappear about a few weeks. The ophthalmologist can explore the eye and perform other tests as needed to determine the basic cause. Patients with pain may be prescribed soothing artificial tears or anti -inflammatory drugs. Other problems such as high blood pressure and diabetes are adequately treated with drugs.
