To investigate the clinical effect and influence of probing of lacrimal passage in congenital obstruction of lacrimal duct.

The clinical data of 76 patients (140 eyes) with congenital obstruction of lacrimal duct from January 2014 to January 2017 in the Inner Mongolia Autonomous Region Baotou Central Hospital were included in this study. According to the order of admission, all the patients were randomly divided into two groups, of which 38 cases were in the observation group and 38 cases in the control group. The control group received routine medication, and the observation group received lacrimal probing. The short-term and long-term effects of the two treatment regimens were compared. The short-term efficacy mainly includes the effective degree of treatment and the time of lacrimal passage function returning to normal. The long term effect mainly deals with the occurrence of postoperative complications and the recurrence of the disease. The curative effect is divided into three grades according to obvious effect, effectiveness and ineffectiveness, the observation group and the control group′s curative effect, the complication total occurrence rate and the total recurrence rate description, uses the case number and the percentage, the two groups′ efficiency comparison uses the χ² test. The time of lacrimal passage recovery was described by (±s) and the two groups were compared with the recovery time of lacrimal passage by t-test.

Patients in the observation group were markedly effective in 17 cases, effective in 19 cases and ineffective in 2 cases, the effective rate was 94.74%; the control group patients markedly effective in 14 cases, effective in 17 cases and ineffective in 7 cases, the effective rate was 81.09%. The difference between the two groups was statistically significant (χ²=4.41, P<0.05). In the control group, the average time of lacrimal passage was (5.65 ±1.25) days, and the average time of lacrimal passage in the observation group was (2.64±0.97) days. The recovery time of the two groups was compared, the difference was statistically significant (t=-12.51, P<0.05). The patient data form, via subcutaneous edema and infection complications such as tear statistics, the total occurrence of complications of the control group the recurrence rate and disease rate were higher than the observation group, the difference was statistically significant (χ²=7.26, 7.24; P<0.05).

The effect of lacrimal passage exploration is significant, which can reduce the incidence of postoperative complications and the probability of disease recurrence. It is beneficial to the recovery of the patient′s condition and the improvement of the prognosis of the disease. It can be used as an effective treatment for congenital obstruction of lacrimal duct.
