Treatment options 1, within 6 months: conservative treatment (1) attention to eyelid hygiene (2) lacrimal sac massage (3) antibiotic eye drops in the conjunctival sac 2, more than 6 months: lacrimal duct exploration 3, the above does not work: feasible lacrimal artificial nasolacrimal duct implantation 4, the above does not work: feasible nasal lacrimal sac anastomosis Other information 1, the vast majority (90-95%) of children heal themselves within 6 months. 2, tear sac massage: be sure to teach parents the technique, otherwise the effect is not good. Apply pressure to the tear sac with your fingers and slide it down the nasolacrimal duct 4 times a day for several weeks. 3.Most of the literature is unified on the timing of lacrimal duct exploration, which is usually done after 6-8 months; the early self-healing rate is very high, so there is no need to rush the exploration. 4, lacrimal tract probing: contraindicated multiple probing, generally an invalid probing again probing success rate is very low, to avoid medical source of lacrimal tract damage. 5, the above invalid: feasible lacrimal artificial nasolacrimal duct implantation. 6, lacrimal sac nasal anastomosis is the final program. At present, nasal endoscopic lacrimal sac nasal anastomosis is promoted internationally.
