Lacrimal duct obstruction, also known as nasolacrimal duct obstruction, is a medical condition characterized by the blockage or narrowing of the lacrimal ducts. The lacrimal ducts are small channels that carry tears from the surface of the eye to the nasal cavity. When these ducts become obstructed, the tears are not able to drain properly, resulting in excessive tearing and possible inflammation or infection of the eyes.
There are various causes of lacrimal duct obstruction, including congenital abnormalities, trauma to the nose or face, infections, and age-related changes. Infants are especially susceptible to this condition, as their lacrimal ducts may not be fully developed at birth. In most cases, the obstruction occurs in one eye, but it can affect both eyes as well.
Symptoms of lacrimal duct obstruction may include excessive tearing, eye redness, eye discharge, swelling around the eyes, and recurring eye infections. Diagnosis of this condition is typically made through a physical examination and an evaluation of the patient's medical history.
Treatment options for lacrimal duct obstruction depend on the severity and cause of the obstruction. Mild cases may resolve spontaneously over time, while more persistent cases may require interventions such as massage of the lacrimal sac, antibiotic eye drops, or surgical procedures to establish proper tear drainage.
Overall, lacrimal duct obstruction is a condition characterized by the blockage or narrowing of the tear ducts, leading to excessive tearing and potential eye infections. Prompt diagnosis and appropriate treatment can help alleviate symptoms and improve eye health.
