Key points
Nasolacrimal duct obstruction can cause watering; congenital and acquired causes differ.
Acute dacryocystitis: local red hot painful swelling needs prompt care — do not squeeze hard yourself.
Infant watering and adult acquired blockage are assessed differently by specialists.
No booking or surgical success-rate comparison on this page.
Tears cannot drain. Infants often improve in the first year; probing is a later option if a doctor advises. Adults may have inflammation or stone. Surgery classes include DCR. This page lists no branded tubes and no success rates.
This is general medical information, not a diagnosis, and cannot replace an in-person consultation with a registered ophthalmologist, refraction, or a dilated fundus exam. It is not advice to use any medicine or undergo any procedure. Medicines (including off-label use), laser or surgery must be decided by a registered doctor after examination, according to indications and Hong Kong registration. Figures from the literature are published averages, not any clinic’s results. This site does not book, prescribe or refer. Do not change treatment on your own.
