Abstract

To determine the factors which can increase the failure after glaucoma filtering surgery and to evaluate the affect of Mitomycin C(MMC) on filtering surgery. We evaluated 249 eyes who underwent glaucoma filtering surgery consecutively during last 2 years in Catholic University Medical College hospitals. 129 eyes had risk factors and 68 eyes of them were treated with MMC during operation. The success rate of the group with risk factors was significantly lower (P=0.001) than that of the group without risk factors. In the risk group, MMC has increased the sucess rate (P=0.07). Previous cataract surgery, neovascularization of iris (NVI) , re-trabeculectomy, young age under 40, uveitis and diabetes were significant risk factors for surgical failure. After adjustment of each factors, previous cataract surgery, NVI, retrabeculectomy and young age still increased the failure rate significantly. Among them we were able to make reduse the effect of re-trabeculectomy and youth by using MMC during surgery. The outcome of glaucoma surgery may increase the success rate in some high risk cases.
