A blocked tear duct, also known as nasolacrimal duct obstruction, occurs when the tear ducts, responsible for draining tears from the eye into the nasal cavity, become obstructed. This blockage can lead to symptoms such as excessive tearing, frequent eye infections, and discharge. Blocked tear ducts can affect individuals of all ages but are particularly common in infants and older adults. In infants, the condition often resolves spontaneously as the duct matures, but in adults, it may be caused by infections, inflammation, or structural abnormalities.
Diagnosis involves a thorough eye examination, including tests to evaluate tear drainage and duct patency. In some cases, imaging studies such as dacryocystography (a type of X-ray) may be used to determine the extent of the blockage. Treatment options for a blocked tear duct vary based on the severity and underlying cause. They may include conservative measures such as warm compresses and gentle massage, medical treatments like antibiotic eye drops, or surgical interventions to clear the obstruction and restore normal tear drainage. Addressing a blocked tear duct is essential to prevent complications and improve eye comfort and function.
