The cornea is devoid of blood vessels, so there is no such thing as a corneal hemorrhage, which is often referred to clinically as a subconjunctival hemorrhage in the eye. The causes of subconjunctival hemorrhage include trauma, inflammation, spontaneous hemorrhage, or patients with systemic diseases. 1. Localized trauma to the eye may cause rupture of the conjunctival blood vessels, manifesting as subconjunctival hemorrhage. 2. Localized inflammation of the eye, such as acute conjunctival inflammation, may cause embolism of tiny blood vessels leading to hemorrhage. 3. Elderly people often experience spontaneous hemorrhage, such as when nausea and vomiting, sneezing, violent coughing or constipation, lifting heavy objects, which may lead to rupture of small blood vessels in the conjunctiva hemorrhage. 4. If the patient has systemic diseases, such as hypertension, arteriosclerosis, diabetes mellitus and blood diseases, the blood vessels of the conjunctiva tend to have increased brittleness and abnormal coagulation function, leading to recurrent hemorrhage under the bulbar conjunctiva. If corneal hemorrhage is accompanied by abnormal vision or eye pain, increased secretion and other discomforts, it is recommended that the patient consult a doctor in a timely manner to clarify the cause of the disease, and intervene in accordance with the doctor’s instructions if necessary.
