Risk factorsBy 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.
