The lacrimal system is responsible for producing and draining tears, which keep the eyes moist and protected. Disorders of this system can lead to excessive tearing, known as epiphora, or insufficient tear production, resulting in dry eyes, or keratoconjunctivitis sicca. These conditions can cause discomfort and may affect vision. Common causes of lacrimal system disorders include blockages in the tear ducts, inflammation, or infections. Treatment options vary depending on the specific disorder and may include medications, punctal plugs, or surgical interventions to restore normal tear flow and alleviate symptoms.
