Can birth control pills cause subconjunctival hemorrhage?

Not that we're aware: Birth control pills are more commonly linked to clotting problems than blood thinning problems. Subconjunctival hemorrhages can occur in anybody, but occur more commonly in people on aspirin, Coumadin (warfarin) and other blood thinning medications.

No: Subconjunctival hemorrhages are typically related to dry eyes, blood thinners, coughing/constipation/ vomiting/ other causes of increased intrabdominal pressure, viral conjunctivitis, and eye rubbing or other trauma. Birth control pills do not increase the risk of sch.

Generally not: Medications can affect people in different ways. I'm not aware of this being a common side affect.

Occasionally: In some women, birth control pills cause some degree of a bleeding tendency. If the eyes are predisposed to have a subconjunctival hemorrhage, this can be worsened by the use of such pills. But they do not cause the initial bleeding which requires fragile vessels and some degree of trauma.
