When your nasal passageways are unable to drain tear liquid from your eyes, you have a blocked tear duct. A blocked tear duct is a full or partial blockage in the nasal passageways that drain tears. This condition is known as Nasolacrimal Duct Obstruction (NLDO).
In such cases, a Dacryocystorhinostomy (DCR) surgery is performed to create a new path for tears to drain between your eyes and your nose. To bypass the blocked tear drain, a new tear drain is constructed between the eye and nose during DCR.
Symptoms of a Blocked Tear Duct:
If your tear ducts are obstructed, you may notice these symptoms in one or both eyes.
- Discharge from the eyes
- Eye irritation
- Excessive tearing (Epiphora)
- Painful swelling in the inner corner of the eye
- Inflammation of the eye
The occurrence of these symptoms may be related to congenital or acquired causes. In children, the majority of Nasolacrimal duct obstruction is congenital and present at birth
A DCR surgery will help alleviate these symptoms. This treatment can be performed either externally (through the skin) or endoscopically (through the nose).
