AIM:To observe the effectiveness of adjustable suture to tear film in patients with acute angle-closure glaucoma in different periods after surgery.

METHODS:Sixty patients(68 eyes)with acute angle-closure glaucoma were divided into study group(trabeculectomy with adjustable suture)and control group(trabeculectomy without adjustable suture). The preoperative and postoperative data including tear break-up time(BUT), Schirmer I test(SⅠt), fluorescent(FL),and signs and symptoms of patients were analyzed respectively.

RESULTS:The results of SⅠt at 7d after surgery and FL at 3d after surgery in the study group were higher than those in the control group(P<0. 05). There were no significant differences on SⅠt and FL between the two groups since the thirtieth day after surgery. The signs of foreign body sensation, conjunctival congestion and photophobia at 1d after surgery in the study group were also higher than those in the control group(P<0.05); since the thirtieth day after surgery, there were no significant differences between two groups(P>0.05).

CONCLUSION:Using the adjustable suture in trabeculectomy will cause temporary impact on the tear film,and it will disappear soon after the suture being dismantled.
