Abstract:AIM: To studythe timing of secondary treatment for neonatal dacryocystitis and the depth of the needle with probing.
METHODS: The treatment effect of the second lacrimal passage after the first treatment failure was analyzed and the depth of the needle was studied.
RESULTS: Due to the recovery rate of the lacrimal passage is related to age, there was no statistically significant difference in age, among the three groups(P>0.05). Divided according to timing, 10 eyes were cured by secondary treatment in less than 1 week, accounting for 91%; 12 eyes were cured in 1-2 weeks, accounting for 92%; 6 eyes were cured in more than 2 weeks, accounting for 75%. There was statistically significant difference in achievement ratio(P>0.05). The achievement ratio was the highest and the complication ratio was the lowest in 1-2 weeks.
CONCLUSION: 1-2 weeks is the best timing of secondary treatment.
