: Twenty four eyes from 23 neovascular glaucoma (NVG) patients, who underwent trabeculectomy with 0.2 or 0.4 mg/ml MMC in least the previous 6 months, were examined in order to evaluate the mid-term effects of a trabeculectomy with mitomycin C (MMC) in NVG. Success defined when an intraocular pressure (IOP) 5 mmHg with or without medication was observed. The mean IOP was reduced from 46.8+/-12.9 mmHg preoperatively to 18.2+/-12.0 mmHg at the last follow-up (mean = 25.8 months). The overall success rates at 1-, 3-, 6-, 9-, and 12-months after surgery were 71%, 58%, 50%, 29%, 29% respectively. The number of anti-glaucoma medications administered was significantly reduced from 2.6+/-0.7 preoperatively to 0.9+/-1.0 postoperatively (Wilcoxon signed rank test, p = 0.005). In addition both the intraoperative MMC concentration and application time had no influence on lowering the IOP (logistic regression analysis, p = 0.228, 0.910, respectively). There was a similar incidence of postoperative complications in both the success and failure group. These results suggest that a trabeculectomy with MMC is an effective surgical procedure in NVG patients and the MMC concentration is not crucial for reducing the IOP postoperatively.

PURPOSE To compare surgical outcomes between patients who underwent Baerveldt glaucoma implantation versus trabeculectomy (TLE) for the treatment of neovascular glaucoma. METHODS We performed a prospective, randomized, controlled clinical trial at Hiroshima University and Tsukazaki Hospital, Japan. Patients were randomized to Baerveldt glaucoma implantation (23 patients) or TLE (27 patients). The primary outcome measure was the rate of intraocular-pressure control. Secondary outcome measures inc...
The administration of postoperative bevacizumab injection in subconjunctival trabeculectomy will reduce bleb fibrosis. This study aimed to investigate the effect of bevacizumab as an antifibrotic agent on collagen density, collagen thickness and type I collagen expression after trabeculectomy in rabbits. Sixteen males New Zealand white rabbits were divided into two groups, control and treatment group. Masson’s trichrome was performed to evaluate collagen density and thickness. Immunohistochemis...

Neovascular glaucoma carries a poor visual prognosis and surgery is frequently required to control the intraocular pressure. For patients who have visual potential, conventional glaucoma surgery such as a glaucoma drainage device or trabeculectomy are frequently performed. Cyclophotocoagulation is often reserved for eyes with poor visual potential, blind eyes, or where for medical reasons it is not possible for patients to have conventional surgery. Furthermore, patients with neovascular glaucom...

ABSTRACTBackground: To report the outcome of intravitreal Bevacizumab followed by Ahmed valve implantation in the management of neovascular glaucoma in a patient group with extended follow-up. Methods: The records of 16 patients (18 eyes) with neovascular glaucoma refractory to medical therapy who presented to a single surgeon between 2006–2008 were reviewed. Patients received pan-retinal photocoagulation and then intravitreal Bevacizumab followed by Ahmed valve implantation. The main outcome me...

Background Several retinal ischemic diseases can cause neovascular glaucoma (NVG). Trabeculectomy with mitomycin C (MMC) is a relatively better treatment modality in the management of eyes with NVG than other glaucoma surgeries. The aim of this study was to investigate the factors that may influence the outcome of trabeculectomy with MMC for NVG.
