Indications for lacrimal passage probing

Lacrimal duct probing is generally suitable for infants with lacrimal duct obstruction in clinical treatment, but it is generally not recommended to use lacrimal duct probing for adult patients. If the nasolacrimal duct of infants is blocked, the eyes are lacrimal for a long time and accompanied by secretions, at this time, it is generally observed for about six months to eight months before examination. At this time, if lacrimal duct is still blocked, it is recommended to perform lacrimal duct probing surgery.
