Abstract:AIM: To evaluate clinical efficacies of different suture of scleral flap in trabeculectomy for the primary acute angle-closure glaucoma.
METHODS: Totally 60 cases(68 eyes)of confirmed primary acute angle-closure glaucoma were randomly divided into two groups. Group A(four-needle suture of scleral flap)were 30 cases(33 eyes). Group B(two-needle suture of scleral flap)were 30 cases(35 eyes). Postoperative intraocular pressure, anterior chamber depth and filtering bleb shape were compared. All cases were followed-up for 6 months.
RESULTS:(1)On the 2nd postoperative day, compared intraocular pressure(IOP)of both groups, the difference was statistically significant(t = 5.8765, P <0 05); 2 weeks of post-operation, compared IOP of both groups, there was no statistically significant difference(t=1.2347, P>0.05); In the 1st month after operation, compared IOP of both groups, the difference was not statistically significant(t=1.4350, P>0.05); In the 3rd month postoperatively, compared IOP of both groups, the difference was not statistically significant(t=1.3548, P>0.05); 6 months after operation, compared IOP of both groups, there was no statistically significant difference(t=1.5753,P>0.05).(2)On the 2nd postoperative day, the incidence rate of shallow anterior chamber in group A was 6%, and that of group B was 17%. Shallow anterior chamber in group A was mainly shallowⅠ. Compared the incidence rate of shallow anterior chamber between both groups, the difference was statistically significant(χ 2=6.4513, P<0.05); 1 week after operation, the incidence rate of shallow anterior chamber in group A was 0 and 3% in group B respectively. Compared the incidence rate of shallow anterior chamber between both groups, the difference was not statistically significant(χ 2=0.7341, P>0.05).(3)functional filtration bubble formation rate of patients of two groups in 1 month and 6 months postoperatively: that of 1 month after operation in group A was 97% and 94% in group B respectively, compared them between two groups, the difference was not statistically significant(χ 2=0.7301, P>0.05); That of 6 months after operation in group A was 88% and 86% in group B respectively, the difference was not statistically significant when compared them between two groups(χ 2=0.8172,P>0.05).
CONCLUSION: In primary acute closed-angle glaucoma underwent trabeculectomy, four stitches of the scleral flap can better control IOP in the short term, and reduce the incidence rate of early shallow anterior chamber.
