AIM:To investigate the influences of composite trabeculectomy for incidence of postoperative shallow anterior chamber, surgical success rate and functional filtering bleb formation rate in patients with glaucoma.

METHODS:Totally 58 patients(64 eyes)with glaucoma who were treated in our hospital from May 2013 to May 2015 were selected. These patients were divided into composite trabeculectomy group(composite group, 28 patients with 32 eyes)and traditional trabeculectomy group(conventional group, 30 patients with 32 eyes)based on a random number table, the incidence of postoperative shallow anterior chamber, success rates and functional bleb formation rates, incidences of concurrent disease of the two groups were statistically analyzed.

RESULTS:The incidence of postoperative anterior chamber of the composite group(6%, 2/32)was significantly lower than that of the conventional group(22%, 7/32; P<0.05). The intraocular pressure(IOP)was significantly lower than that of the conventional group(P<0.05). The success rate of the composite group(88%, 28/32)was significantly higher than that of the conventional group(44%, 14/32)(P<0.05). The functional bleb formation rate of the composite group(91%, 29/32)was significantly higher than that of the conventional group(69%, 22/32, P<0.05). The postoperative complication rate of the composite group(9%, 3/32)was significantly lower than that of the conventional group(25%, 8/32, P<0.05).

CONCLUSION:Composite trabeculectomy can more effectively reduce the incidence of postoperative shallow anterior chamber, and improve the success rate of functional bleb formation and reduce the complications rate in glaucoma patients than traditional trabeculectomy, it is safe and effective.
