Abstract•AlM:To compare the effects of different adjustable suture in glaucoma trabeculectomy on early tear film function.•METHODS:Sixty-eight cases of primary glaucoma ( 76 eyes) during January 2012 to June 2014 in our hospital were selected and divided into exposure conjunctival suture group ( 34 cases, 36 eyes ) and embedded conjunctival suture group ( 34 cases, 40 eyes ) according to treatment. Adjustable suture exposed conjunctival suture and embedding conjunctival suture was given to two groups, respectively. lntraocular pressure ( lOP ) before and after treatment 7, 14, 30d were observed and Schirmer test, tear break-up time, No Hikaru sensitivity and the occurrence of adverse reactions after treatment 1, 30d were recorded.•RESULTS: After the treatment, the mean lOP of two groups were decreased significantly ( P 0. 05), after treatment 7, 14, 30d embedded conjunctival suture group was significantly higher than that of exposure conjunctival suture group ( P0.05),治疗后7,14,30d包埋结膜缝线组平均眼压显著高于暴露结膜缝线组(P0.05),治疗后7,14,30 d包埋结膜缝线组Schirmer试验、泪膜破裂时间显著优于暴露结膜缝线组(P<0.05)。治疗后30 d包埋结膜缝线组不良反应发生率显著低于暴露结膜缝线组(P<0.05)。结论：小梁切除手术可调节线包埋结膜缝合对患者早期泪膜功能影响较小,术后并发症较低,手术效果优于暴露结膜缝合。
