Evaluation the cinical effect of trabeculectomy with releasable suture in the treatment of angle-close glaucoma

Objective To evaluate the clinical effect of trabeculectomy with releasable suture in treatment of angle-gluaucoma patients.Methods Clinical data of 147 patients(159 eyes) undergone trabeculectomy with releasable suture(releasable suture group) and 162 patients(174 eyes) undergone routine trabeculectomy(control group) were retrospectively reviewed.Before and surgery,visual acuity,IOP,depth of the anterior chamber,filtration bleb of each patient was under carefully observed.The mean follow-up period was 30 months.Results In patients went trabeculectomy with releasable sutures,the time for stable anterior chamber formation after the surgery,which was significantly shorter than the control group(P0.001).The post-operative IOP in the releasable suture group was(11.77±3.37) mmHg,which was significantly(t=25.86,P=0.000) lower than it was before the surgery(31.63±9.45) mmHg.At the last visit,the IOP of the releasable suture group was(14.74±2.71) mmHg,which was again significantly(t=11.22,P=0.000) lower than the IOP of the control group(17.96±2.45 mmHg).Neither ocular infection nor malignant glaucoma was observed in the releasable suture group.Conclusion Trabeculectomy with releasable suture benefits the anterior chamber formation after surgery and long-term IOP control in the treamtment of angle-close glaucoma.
