Nasolacrimal Duct Obstruction in Adults

Nasolacrimal duct obstruction is commonly seen in adults and often occurs spontaneously without a specific cause. In some cases, it may result from trauma that damages or blocks the tear drainage system. The most common symptom is excessive tearing (epiphora), with some patients experiencing constant tearing throughout the day, requiring tissue paper to frequently wipe away tears.

This persistent tearing can cause inconvenience and negatively impact one's appearance and quality of life, especially during social interactions, activities, or driving. Moreover, blocked tear ducts hinder the proper drainage of tears, causing debris and bacteria to accumulate on the eye surface, which can lead to various eye problems such as:

- Chronic allergic conjunctivitis

- Blepharitis (inflammation of the eyelids)

- Dry eye syndrome

- Eye infections

Understanding the Tear Drainage System

The tear drainage system can be compared to the drainage system in a house. Normally, when the drainage system works properly, wastewater flows out smoothly, keeping the area clean. However, when the drainage system is blocked, waste and dirty water accumulate, causing inflammation and contamination.

Similarly, when the nasolacrimal duct is obstructed, tears mixed with debris cannot drain properly, leading to persistent irritation and inflammation of the eyes. This condition is akin to a clogged drainage system in a house that has not been repaired, causing continuous problems until proper treatment is administered.
