About the symptom

This can happen when the eye is inflamed or irritated, such as when you have allergies or an eye infection. Excess tears are the body's attempt to wash away whatever is irritating the eye.

Possible causes

  • Cluster headache

    This condition presents with repetitive brief headaches that occur as episodes of severe pain (characteristically on one side of the head) associated with possible eye redness/tearing or runny nose, occurring in bouts or "clusters" of several per day, possibly lasting for weeks or even months in a row. The pain can be disabling, interfering greatly with daily life.

  • Intraocular foreign body

    Intraocular foreign bodies are unintentional projectiles that retained in the eye which require urgent diagnosis. If left unattended, it may lead to vision loss and blindness.
