Massive bleeding from the white of the eye is called subconjunctival hemorrhage. There are many causes of subconjunctival hemorrhage, such as violent coughing after a cold, vomiting after drinking, straining during dry stools, as well as trauma, hypertension, arteriosclerosis, and blood disorders that can cause massive subconjunctival hemorrhage. The initial bleeding is bright red and later turns black, and is usually absorbed in 7-12 days. However, many people do not pay attention to the bleeding afterwards and rubbing their eyes hard can increase the bleeding. It is important to find the cause of the bleeding and to treat the cause. In the early stage of bleeding, local cold compresses should be applied, and after 2 days, hot compresses should be applied, and oral medications should be taken to stop bleeding and eliminate stasis, such as blood stasis and bright eye tablets, and blood bright eye tablets.
