Study of lacrimal duct probing in the treatment of congenital dacryocystitis

Objective To observe the therapeutic effect of lacrimal passage on congenital dacryocystitis.Methods One hundred and fifty patients (160 eyes) with congenital dacryocystitis were treated with lacrimal passage by a self-made probe, which was reformed by an ordinary intramuscular needle with the end of the needle tapered and round blunt. An assistant was needed to fix the head of the baby. Probing was performed mainly from the superior lacrimal puncta. Operation included compressive rinsing, probing, occlusion extending and so on. Results One week after the operation,136 eyes were cured by 1 time, 15 eyes by 2 times,5 eyes by 3 times and 4 eyes were not cured. No false passage or subcutaneous edema was observed. A little nasal bleeding occurred in 2 cases, which disappeared later without treatment.Conclusions The probing needle combining probing with washing could function and facilitate the operation.
