Subconjunctival Hemorrhage

A subconjunctival hemorrhage is a bright red patch on the white of the eye caused by a small broken blood vessel. It looks alarming but is usually harmless and clears on its own in one to two weeks.

Understanding Subconjunctival Hemorrhage

It can follow coughing, sneezing, straining, rubbing the eye, or minor injury, and is more common in people who take blood thinners or have high blood pressure. It typically causes no pain or vision change.

Common symptoms

  • A bright red patch on the white of the eye
  • No pain and no change in vision
