METHODS: Retrospective case series reseach was undertaken. We divided the 71 cases(including primary open angle glaucoma and primary chronic angle-closure glaucoma)into two groups: MMC group(36 cases)and 5-FU group(35 cases). Both were treated with combined adjustable sutural trabeculectomy with the usage of MMC or 5-FU anti-cicatricial treatment, and followed up to compare intraocular pressure, filtered bubble form and complications.

RESULTS: The intraocular pressure of MMC group was lower than 5-FU group with statistical significance(P<0.05); there was no significant difference in total surgical success rate between groups(P>0.05). Functional filtering bleb formation rate in MMC group was higher than 5-FU group while the formation rate of nonfunctional filtering bleb in MMC group was lower than 5-FU group(P<0.05), which showed no significant difference in complication rate between groups(P>0.05), but the types of complications were different.

CONCLUSION: Both MMC and 5-FU can improve the success rate of glaucoma trabeculectomy as anti-cicatricial drugs. MMC can lower the intraocular pressure, is superior to 5-FU in the formation of functional filtering bleb. There was no significant difference in the incidence of complications between MMC and 5-FU according to personalized surgical protocols based on patients. When 5-FU is used, it is necessary to separate the filtering blebs repeatedly after operation and to reinject 5-FU under conjunctiva.
