Background: To determine the success of repeat trabeculectomy augmented with mitomycin C in a cohort of patients who had undergone previously failed trabeculectomy surgery. Design: A consecutive cohort series of patients. Participants: Fifty patients undergoing augmented trabeculectomy surgery following a previously failed trabeculectomy and at least 12months' follow up. Methods: All patients had demographic and clinical data collected at the time of surgery and at all subsequent follow-up visits. Main Outcome Measures: Visual field progression, loss of visual acuity, intraocular pressure (IOP) control. Results: The mean follow up was 36.7months. Forty-one patients (82%) achieved an IOP (less-than or equal to)21mmHg (with (greater-than or equal to)20% reduction of preoperative IOP) and (greater-than or equal to)6mmHg on no additional glaucoma treatment at 12months' follow up. Forty-four patients (88%) achieved a qualified success with the same criteria at 1year. The median logMAR acuity preoperative was unchanged after surgery; however, 11 patients (22%) lost (greater-than or equal to)2 Snellen lines during follow up. There was no significant change in mean deviation during the follow-up period. Conclusions: Repeating trabeculectomy augmented with mitomycin C is an effective method of controlling IOP and preventing further visual deterioration in the majority of patients treated. However, visual loss was seen in a significant proportion of patients. (copyright) 2011 Royal Australian and New Zealand College of Ophthalmologists.
