Risk factors

By Mayo Clinic staff

Risk factors for subconjunctival hemorrhage include:

  • Diabetes or high blood pressure (hypertension)
  • Illnesses that causes severe coughing or sneezing
  • Certain blood-thinning medications, such as warfarin (Coumadin) and aspirin
  • Herbal supplements, such as ginkgo, that increase the potential for bleeding in the eye

Subconjunctival hemorrhage can also occur among newborns, who may be subjected to pressure changes during delivery.
