Purpose To compare the surgical outcomes and bleb morphology of limbal- based group with that of fornix-based group undergone trabeculectomy with mitomycin C (MMC). Methods 50 eyes of 50 patients with trabeculectomy with MMC who were observed for 1 year were included in the study. A limbal-based conjunctival flap was used for 25 eyes of 25 patients and a fornix-based conjunctival flap for the other 25 eyes of 25 patients. We classified and compared the bleb morphology according to the Moorfield Bleb Grading Sistem after 1 year postoperatively, and evaluated intraocular pressure, success rates. Results There was no significant difference in the IOP and success rate in two groups. The central bleb vascularity of the limbal-based group was stadistically lower than that of fornix-based group (1,69±0,56 : 2,08 ±0,69, p=0,042). The risk of cystic bleb formation was higher in the limbal-based group (34,2% : 14,6% , p = 0,047). Conclusion There was no difference between the groups in the IOP and cumulative succes rate, but fornix-based group was recommendable concerning the low risk of cystic bleb formation. |
