The doctor explained to Mr. Zhang that this was a subconjunctival hemorrhage. What is subconjunctival hemorrhage? The surface of the white of the eye is a thin membrane called the bulbar conjunctiva. If the blood vessels in the bulbar conjunctiva rupture, it can cause subconjunctival hemorrhage. Since the subconjunctival tissue is loose, blood can easily accumulate into flakes after bleeding, which looks like bright red flakes of blood, and when there is a lot of bleeding, the entire white of the eye turns bright red. The bleeding can gradually change from bright red to brown, and the color slowly becomes lighter, usually absorbing on its own within 1 to 2 weeks. Why does subconjunctival hemorrhage occur? The exact cause of subconjunctival hemorrhage can rarely be found. Possible related factors are: 1) constipation; 2) violent cough; 3) violent vomiting; 4) heavy lifting; 5) trauma; 6) hypertension; 7) arteriosclerosis; 8) nephritis; 9) blood disorders; 10) some infectious diseases (sepsis, typhoid, etc.); 11) conjunctivitis. How to treat subconjunctival hemorrhage 1. First of all, look for the cause of the bleeding and treat the cause. If subconjunctival hemorrhage occurs repeatedly, systemic systemic diseases should be investigated. 2, early bleeding can be eye cold compress, bleeding two days after the change to hot compress, 2 to 3 times a day, to help the absorption of bleeding.
