Abstract:Objective To explore the application and clinical effect of adjustable suture in trabeculectomy for glaucoma. Methods Eighty patients (97 eyes) with glaucoma from August 2016 to January 2018 were selected and randomly divided into control group (n=40, 46 eyes) and observation group (n=40, 51 eyes).The trabeculectomy was performed in control group, while the adjustable sutured scleral flap was added in observation group.Intraocular pressures before and after operation, anterior chamber depth, the morphology of filtering bleb and incidence of scleral flap adhesion after operation were compared between two groups. Results At 2 weeks and 6 months after operation, the intraocular pressure in the observation group was significantly lower than that in the control group (P<0.01), and the number of shallow anterior chamber eyes in observation group was significantly less than that in control group (P<0.05, P<0.01).Two weeks after operation, there was no significant difference in the morphology of filtering blebs between two groups (χ²=0.264, P=0.607), but the functional filtering bleb formation rate in observation group was significantly higher than that in control group at 6 months after operation (94.12% vs 78.26%, χ²=5.240, P=0.022).Two weeks after operation, there was no significant difference in scleral flap adhesion between obervation group and control group (0 vs 2.17%, P=0.474).At 6 months after operation, the incidence of scleral flap adhesion in observation group was significantly lower than that in control group ［3.92% (2/51)vs 19.57% (9/46), χ²=5.887, P=0.015]. Conclusion The application of adjustable suture in trabeculectomy for glaucoma is safe and reliable.
