Causes

By Mayo Clinic staff

The cause of subconjunctival hemorrhage is usually unknown. However, the following actions may be enough to cause a small blood vessel to rupture in your eye:

  • Violent coughing
  • Powerful sneezing
  • Heavy lifting
  • Vomiting

In some cases, subconjunctival hemorrhage may result from an eye injury, such as from:

  • Roughly rubbing your eye
  • Severe eye infection
  • Eye or eyelid surgery
