This study aimed at evaluating the efficacy and safety of adjunctive intravitreal bevacizumab （IVB） injection in conjunction with Ahmed glaucoma valve implantation （AGVI） in the management of NVG. Methods This was a retrospective study of patients with NVG in whom AGVI was performed between October 2008 and May 2012. The sample was divided into two groups according to the pretreatment： with adjunctive IVB injection （the IVB group, n=25 eyes） and without adjunctive IVB injection （the control group, n=28 eyes）. The surgical success rate, number of antiglaucoma medications used, best-corrected visual acuity （BCVA）, postoperative complications, regression, and recurrence of iris neovascularization （NVI） were analyzed between the groups. Results The surgical outcomes of the two groups were compared. The complete success rates in the IVB and control groups were 84.0% and 64.3% at 12 months and 80.0% and 53.6% at 18 months, respectively. There was a significant difference between the two groups （P=0.041）. Mean postoperative intraocular pressures, mean number of postoperative antiglaucoma medications, and BCVA were not significant between the two groups. The NVI in 22 （88.0%） eyes had completely regressed within 2-8 days after IVB. However, NVI recurred in 10 eyes （40.0%） 2-9 months later after IVB. The IVB group had only 1 case （4.0%） of hyphema out of 25 eyes, while there were 8 （28.6%） cases of hyphema out of 28 eyes in the control group （P=0.026）.Conclusions This study showed that preoperative IVB injection reduced NVI remarkably, decreased hyphema, and led to higher surgical success rates. Pre-operative IVB injection may be an effective adjunct to AGVI in the management of NVG.展开更多
