Utako Kuroda, Toshihiro Inoue, Nanako Awai-Kasaoka, Kohei Shobayashi, Sachi Kojima, Hidenobu TaniharaDepartment of Ophthalmology, Faculty of Life Sciences, Kumamoto University, Kumamoto, JapanPurpose: To compare the surgical outcomes of limbal-based and fornix-based trabeculectomy in eyes with a history of ocular incisional surgery.Methods: Twenty-six eyes underwent limbal-based trabeculectomy (group LB), and were condition matched with 26 eyes that received fornix-based trabeculectomy (group FB). Surgical failure was recorded retrospectively if the intraocular pressure value was either ≥21, ≥18, and ≥15 mmHg (conditions A, B, and C, respectively) or
