Bleeding from the eye can be caused by a variety of factors, including trauma to the eye or inflammatory diseases of the eye surface. The surface of the eye is rich in blood vessels and bleeding can easily result in eyelid hematomas and subconjunctival hemorrhagic spots. Therefore, if there is trauma to the eye, it may directly cause lacerations to the skin of the eyelid or conjunctival trauma, both of which can cause small superficial blood vessels to rupture and bleed. In addition, inflammatory diseases may also cause bleeding, such as severe acute conjunctivitis, or blepharitis in which the pus is mature and breaks on its own, resulting in simultaneous bleeding. If the bleeding is caused by trauma to the eye, local pressure should be considered to stop the bleeding, and then the patient should be taken to the hospital for symptomatic treatment. If it is a superficial rupture of a small blood vessel, the bleeding can usually be temporarily stopped on its own by applying pressure, but if the bleeding is obvious, it needs to be cleaned and sutured. If it is caused by inflammation, the amount of bleeding is usually very small and may be manifested as blood mixed in the discharge, so the treatment still needs to be treated with antibiotic eye drops, as well as antibiotic eye ointment.
