Tears normally drain through the lacrimal puncta towards the nose, via the nasolacrimal duct. With age, this duct can narrow and then block (stenosis): tears overflow and the eye waters constantly. It is the leading cause of chronic watery eyes in adults.
The signs
Constant watering, worse in cold and wind, overflowing onto the cheek; repeated discharge, and sometimes episodes of lacrimal sac infection (dacryocystitis).
The diagnosis
The examination includes probing and irrigation of the tear ducts at the practice — a quick, only mildly uncomfortable procedure that locates the obstruction precisely. A dacryo-CT scan may complete the work-up in selected cases.
The treatment
When the duct is blocked, treatment is surgical: dacryocystorhinostomy (DCR) creates a direct passage between the lacrimal sac and the nose, with an excellent success rate. Partial stenoses may be managed with dilation or intubation.
Frequently asked questions
Can simple irrigation be enough?
Probing and irrigation are primarily diagnostic. In some partial stenoses, dilation or temporary intubation can improve drainage; in complete obstruction, only surgery is effective.
