AIM: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. Intraocular pressure(IOP)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 IOP of two groups were decreased significantly(P<0.05). The average IOP after treatment of 1d in the two groups were not statistically different(P>0.05), after treatment 7, 14, 30d embedded conjunctival suture group was significantly higher than that of exposure conjunctival suture group(P<0.05). After 1d of treatment, Schirmer test, tear break-up time, No Hikaru sensitivity of two groups compared no significant difference(P<0.05). After treatment 7, 14, 30d embedded conjunctival suture group Schirmer test, tear break-up time, was significantly superior to expose conjunctiva suture group(P<0.05). The 30d package after treatment of conjunctival suture group buried adverse reaction rate was significantly lower than that of exposed conjunctival suture group(P<0.05).

CONCLUSION:Trabeculectomy operation with adjustable thread embedding conjunctival suture has few effects on the tear film function in patients with early postoperative complications, lower, and operation effect is better than that of exposed conjunctival suture.
