Angulated Distal Suture Trabeculectomy for Treatment of Primary Angle-closure Glaucoma.

Objective To investigate the clinical effects of angulated distal suture trabeculectomy on primary angle-closure glaucoma (PACG) . Methods We selected 105 eyes of 85 inpatients suffering from PACG in our department from Sept. 2011 to Dec. 2013 as research object. The enrolled patients were randomly divided into observation group and control group. Patients in observation group were treated with angulated distal suture trabeculectomy while patients in control group were treated with Traditional trabeculectomy. Then we observed and followed up shallow anterior chamber, functional filtering bleb, success rate of operation and the incidence of complication in the two groups. Results In the formation of functional filtering bleb and success rate of operation between the two groups, there was no statistically significant difference 3 months after operation (P> 0.05), while there were statistically significant differences 6 months and 1 year after operation (P < 0.05). In early-stage complications such as ocular hypotony, shallow anterior chamber in the corresponding period between the two groups, there was no statistically significant difference (P> 0.05) . There were no suprachorodal hemorrhage and malignant glaucoma in the two groups. Conclusion Angulated distal suture trabeculectomy is more helpful for long-dated functional filtering bleb formation and better in controlling intraocular pressure in PACG, it is a more ideal operation method.
