Dacryocystorhinostomy (DCR) is a surgical procedure used to treat a blocked tear duct, particularly when tears cannot drain normally from the eye into the nose. This can cause persistent watering, discharge, irritation, or recurrent infections around the tear drainage system.
During DCR surgery, the surgeon creates a new drainage pathway between the tear sac and the nasal cavity, allowing tears to drain more normally. Depending on the patient's condition, DCR may be performed through a small incision near the nose (external DCR) or through the nasal passage using an endoscope (endoscopic DCR).
When Is DCR Recommended?
DCR may be considered for people with persistent watery eyes (epiphora) caused by nasolacrimal duct obstruction, recurrent tear-sac infections, or significant blockage of the tear drainage system. An eye specialist evaluates the symptoms and drainage pathway before recommending surgery.
Benefits of DCR
The procedure is intended to improve tear drainage and may help reduce excessive watering, discharge, and recurrent infections associated with tear duct blockage. The appropriate surgical approach depends on the location and cause of the obstruction.
Recovery After DCR
Recovery varies depending on the surgical technique and individual health. Patients may experience temporary swelling, nasal congestion, or mild discomfort after surgery. Follow-up appointments are important to assess healing and ensure the new drainage pathway remains open.
Is DCR Right for You?
If you have persistent blocked tear duct symptoms, frequent watering of the eyes, or recurrent tear-sac infections, an ophthalmologist can assess whether DCR surgery is appropriate for you.
