Congenital nasolacrimal duct obstruction (CNLDO) is a common ophthalmic condition in children, presenting with tearing and pus overflow, with a prevalence of 5%-20% within 1 year of age. Although most cases resolve spontaneously within 1 year of age, some children require treatment. Lacrimal sac massage is a non-invasive, easy and cost-effective conservative treatment that helps to unblock the obstruction by increasing the pressure in the tear duct. Studies have shown that massage has a 93% cure rate in children under 8 months of age. In contrast, tear duct probing is effective but invasive and risky. In recent years, with the development of minimally invasive techniques, lacrimal sac massage has received renewed attention, and studies have shown its efficacy to be comparable to probing. However, there are problems of non-standardized massage timing and techniques in clinical practice, which affects the therapeutic efficacy. This study aims to assess whether the efficacy of standardized dacryocystic massage is not inferior to that of dacryocystorhinostomy through a randomized controlled trial, providing a reference for the treatment of CNLDO.

In-office tear duct exploratory surgery was performed on the study participants, and the children were closely monitored for healing after the procedure. The children were closely monitored for healing afterward, and the patients were also examined at 1 week, 1 month, and 2 months after the start of treatment.
At the time of the visit, the patient's parents (one of them) were given Standardized tear duct massage (Crigler massage)Teaching and hands-on practice were performed, with the researcher confirming the standardization of movements.Subsequent massages were performed by the family member who received the training, and the child's family swiped the card to access the program.completed by the family member of the child, who scanned the code to enter the small program punch card group, according to the standardized process of massage (the frequency of massage was not less than 3 times/day, each time no less than 4 eight beats)And complete the punch card on time (each punch card interval should be greater than 2 hours).(each clock interval should be more than 2 hours).
Treatment success of congenital tear duct obstruction at 3 months of treatment
Cure rate of congenital lacrimal obstruction at 3 months of treatment: patients with symptoms of lacrimal obstruction (tearing, pus overflow) disappeared are considered cured; lacrimal irrigation patency rate at 3 months of treatment (all lacrimal irrigation fluid goes into the throat, and no reflux is considered to be patency)
Time frame: At 3 months of starting treatment
Lacrimal flushing patency at 3 months after the start of treatment
Whether the tear duct flushing is smooth
Time frame: at 3 months after the start of treatment
Incidence of complications during treatment
Counting adverse events over the course of 3 months of treatment
Time frame: at 3 months after the start of treatment
Recurrence of symptoms within 1 month of cure
Observe whether the patient has recurrence of tearing and pus overflow symptoms within 1 month after cure
Time frame: 1 month after cure
