What Are the Complications of a Broken Blood Vessel in the Eye?

Complications of a subconjunctival hemorrhage, or broken blood vessel in eye, are rare, according to Mayo Clinic. If the condition is due to eye trauma, a doctor may evaluate the eye to ensure the patient does not have other eye complications or injury.

A subconjunctival hemorrhage often occurs without any obvious harm to the eye, explains Mayo Clinic. The most common sign of this condition is a bright red patch on the sclera, or the white part of the eye. This type of hemorrhage occurs when a tiny blood vessel breaks just underneath the clear surface of the conjunctiva, sometimes as the result of a strong sneeze or cough that caused a blood vessel to break. A sunconjunctival hemorrage may also occur as a result of roughly rubbing the eye, severe eye infection or trauma, such as a foreign object injuring the eye.

Despite its bloody appearance, a subconjunctival hemorrhage should cause no change in vision, no eye discharge and no pain, notes Mayo Clinic. However, there may be a scratchy feeling on the surface of the eye. The condition is usually harmless, and any eye redness should disappear on its own within one or two weeks, without any additional medical treatment.

If there are multiple occurrences of subconjunctival hemorrhages, it is important to consult with a doctor.
