Purpose: To determine the long term efficacy of augmented small flap trabeculectomy (microtrabeculectomy) in terms of intraocular pressure (IOP) control in eyes with risk factors for failure Methods: A case-note review of a consecutive series of augmented microtrabeculectomy procedures performed on 59 eyes from 59 patients with a minimum follow up of 12 months. Results: Results: The mean age at surgery was 55 years and the mean (range) number of risk factors for failure was 1.67 (1-4). 5FU was used in 54 cases, with MMC in 5 and the mean follow-up was 5.6 years. The mean (SD) intraocular pressures at presentation and preoperative was 31.61 (8.00) and 28.9 (8.19)mmHg. At 6 months, 1, 2, 3, 4, 5 and 6 years postoperatively the mean (n, SD) IOPs (mmHg) of those eyes followed to each time point were 15.7(59, 5.15), 17.6 (59, 5.8), 15.7 (57, 6.19), 15.9 (56, 4.67), 16.1 (53, 4.27), 16.4 (44, 5.01) and 16.6 (33, 4.66) respectively. Later success rates will be defined by Kaplan Meier analysis. Conclusions: Microtrabeculectomy is effective in control of intraocular pressure in eyes with risk factors for failure
