The Outcomes of Bleb Revision Surgery Techniques After Trabeculectomy

Pur po se: To evaluate the techniques and the results of revision surgeries in order to manage bleb failure after trabeculectomy. Ma te ri al and Met hod: The records of 23 eyes who had undergone bleb revision surgery because of bleb failure after trabeculectomy between December 2002 and September 2009 were analyzed retrospectively. The mean age of the patients was 53.7±24.5 years. The mean intraocular pressure (IOP) before revision surgery was 32,4 ± 8,1 mmHg. Seven cases had needling, 7 had bleb revision surgery, 8 had repeat trabeculectomy, and 1 had scleral suture removal. Re sults: Sixteen cases were successfully treated, while 2 cases had this success with medication and 7 were unsuccessful with revision surgeries. The decrease in the IOP values was statistically significant in all visits after the surgeries (p
