Subconjunctival HemorrhageSubconjunctival hemorrhage occurs when a small blood vessel under the conjunctiva breaks and bleeds. It may occur spontaneously or from coughing, heavy lifting, or vomiting. In some cases, it may develop following eye surgery or trauma. Subconjunctival hemorrhage tends to be more common among those with diabetes and hypertension.
