Kaplan–Meier survival plots of the study groups.

Notes: Kaplan–Meier survival plots of the study groups according to the manner of the conjunctival flap: fornix-based (FB, solid line) or limbal-based (LB, dotted line). Both groups consisted of 26 eyes of 26 patients. (A) Surgical failure was defined as an intraocular pressure (IOP) value of ≥21, an IOP value of <4 mmHg, and additional glaucoma surgery. The probability of success of the trabeculectomy was not significantly different between groups (P=0.124). (B) Surgical failure was defined as an IOP value of ≥18, an IOP value of <4 mmHg, and additional glaucoma surgery. The probability of success of the trabeculectomy was not significantly different between groups (P=0.638). (C) Surgical failure was defined as an IOP value of ≥15, an IOP value of <4 mmHg, and additional glaucoma surgery. The probability of success of the trabeculectomy was not significantly different between groups (P=0.454).
