Application of intraoperative adjustable suture in trabeculectomy

Objective To observe the clinical effect of intraoperative adjustable suture in trabeculectomy.Methods Trabeculectomy were done in 109 cases (121 eyes) of primary glaucoma,intraoperative adjustable suture was used in scleral flap.Postoperative anterior chamber depth,intraocular pressure and filtering bleb were observed.Results Within 1 week after operation,shallow anterior chamber of degree Ⅰ occurred in 3 eyes and shallow anterior chamber of degree Ⅱ in 2 eyes,no shallow anterior chamber of degree Ⅲ occurred.The shallow anterior chamber rate was 4.13％.The intraocular pressure was 9-20mmHg (averaged 12.5mmHg) in 1 week after operation and 9-26mmHg (averaged 14.3mmHg) in 1 month after operation.In 3 months after operation,degree Ⅰ filtering bleb was in 32 eyes,degree Ⅱ filtering bleb in 86 eyes,degree Ⅲ filtering bleb in 2 eyes,degree Ⅳ filtering bleb was in 1 eye,and functional filtering bleb was in 118 eyes (97.5％).Conclusions Intraoperative adjustable suture in trabeculectomy is simple,safe and effective.
