Efficacy of Houttuynia Cordata Eye Drops combined with naso lacrimal duct probing in treating children with nasolacrimal duct obstruction and chronic dacryocystitis
Objective To evaluate the therapeutic effect of Houttuynia Cordata Eye Drops combined with naso lacrimal duct probing in children with naso lacrimal duct obstruction and chronic dacryocystitis.Methods A total of 196 children with naso lacrimal duct obstruction complicated with chronic dacryocystitis admitted to Baoding Maternal and Child Health Hospital in Hebei Province from August 2021 to August 2022 were se-lected as study subjects,and the children were divided into control group and observation group by random number table method,with 98 cases in each group.The control group was given naso lacrimal duct probing,and the observation group was treated with naso lacrimal duct probing com-bined with Houttuynia Cordata Eye Drops.The clinical efficacy of children in the two groups was recorded,and the levels of inflammation factors,tear secretion,tear film break-up time,tear river height,corneal fluorescein staining(FLS)score,and meibomian gland secretion status of children in the two groups were compared before,and after three months of treatment,and the incidence of complications such as hemorrhage,tissue edema,eye membrane scratch of children and family satisfaction were compared between the two groups.Results The clinical efficacy of the observation group was better than that of the control group,the difference was statistically significant(P＜0.05).There were no significant differences in the levels of inflammation factors and ocular symptoms before treatment(P＞0.05).After treatment,the levels of inflammation factors,FLS score,mei-bomian gland secretion status score,tear secretion,and tear river height after treatment were lower than those before treatment,and the tear film break-up time in the observation group was longer than that before treatment,the tear film break-up time in the observation group was longer than that before treatment,the differences were statistically significant(P＜0.05).The incidence of postoperative complications in the observation group was lower than that in the control group,and the satisfaction of family members was better than that in the control group,the differences were statis-tically significant(P＜0.05).Conclusion Naso lacrimal duct probing combined with Houttuynia Cordata Eye Drops irrigation can reduce the level of inflammatory factors and improve ocular symptoms after surgery,thereby improving the treatment effect.
