Congenital Stenosis and Stricture of Lacrimal Duct: Understanding the Condition

Congenital stenosis and stricture of the lacrimal duct, also known as congenital nasolacrimal duct obstruction (CNLDO), is a common condition in newborns. It occurs when the tear duct, which is responsible for draining tears from the eye into the nose, is partially or completely blocked.

Signs of congenital stenosis and stricture of the lacrimal duct may include excessive tearing, discharge from the eye, and occasionally, a swollen and red eye. This condition can affect one or both eyes, and it typically becomes apparent within the first few weeks after birth.

While the exact cause of CNLDO is still not fully understood, it is believed to be due to a failure of the nasolacrimal duct to open properly during fetal development. This can result in the accumulation of tears, leading to discomfort and potential infection.

Diagnosing congenital stenosis and stricture of the lacrimal duct involves a thorough examination of the eye and tear duct system. An ophthalmologist or pediatrician may perform a dye disappearance test or use a special instrument to evaluate the drainage of tears from the eye.

1. Massage: For mild cases, gentle massage over the tear duct area can help open the blocked duct. Parents are often advised to perform this massage technique several times a day to promote tear drainage.
2. Warm compresses: Applying warm compresses to the affected eye can help relieve symptoms and encourage the opening of the blocked duct.
3. Antibiotic eye drops: In some cases, antibiotic eye drops may be prescribed to prevent infection resulting from the accumulation of tears.

In most cases, congenital stenosis and stricture of the lacrimal duct resolves on its own within the first year of life. However, if the condition persists beyond this period or causes recurrent infections, a consultation with an ophthalmologist may be necessary to explore further treatment options.
