Obiective By comparing the break-up time and Schirmer I test of dry eye patients before and after 1 and 3 month of lacrimal punctum embolization.,Analyze the influence of lacrimal punctum embolization on the patients with dry eye tear quality. Methods In this prospective cohert study , 31 dry eye patients (42 eyes) from Peking University ShenZhen Hospital. Break-up time and Schirmer I test were tested at before and after 1 and 3 month of lacrimal punctum embolization. A one-way ANOVA was used for data analysis. Results The mean BUT of dry eye patient before and after 1 and 3 month of lacrimal punctum embolization, (4.12±1.57)S, (8.33±1.62)S, (7.67±1.60)S,respectively. The difference between the three datas was statistically significant (P<0.005). Further comparison each others shows , BUT value of preoperative group significantly less than group 1 month after surgery (P<0.005), BUT value of preoperative group significantly less than group 3 month after surgery (P<0.005), BUT value of group 1 month after surgery significantly less than group 3 month after surgery (P<0.005). The mean Schirmer I test of dry eye patient before and after 1 and 3 month of lacrimal punctum embolization, (3.47±0.48)mm, (7.88±2.49)mm, (6.99±2.00) mm,respectively. The difference between the three datas was statistically significant (P<0.005). Further comparison each others shows , Schirmer I value of preoperative group significantly less than group 1 month after surgery (P<0.005), Schirmer I value of preoperative group significantly less than group 3 month after surgery (P<0.005), Schirmer I value of group 1 month after surgery significantly less than group 3 month after surgery (P<0.005). Conclusion Influence of lacrimal punctum embolization can obviously increase the Schirmer I test in patients with dry eye, appears stability obviously improved,But with the extension of time.
