A Prospective Study to Evaluate Intravitreous Ranibizumab as Adjunctive Treatment for Trabeculectomy in Neovascular Glaucoma.


ABSTRACT: INTRODUCTION: The present study aimed to evaluate the effects of intravitreal ranibizumab (IVR) as adjunctive treatment for trabeculectomy with mitomycin C (TMC) in neovascular glaucoma (NVG). METHODS: This is a prospective study of 15 eyes from 14 consecutive patients with NVG carried out between December 2008 and December 2009. Each eye received IVR (0.5 mg/0.05 ml) 1 week before TMC. Trabeculectomy was performed with fornix-based conjunctival flap method. After TMC, additional panretinal photocoagulation (PRP), subconjunctival five fluorouracil injection, and bleb needling may be performed if indicated. The primary outcome measures were post-TMC intraocular pressure (IOP) and numbers of anti-glaucoma medication. The secondary outcome measures included of the recurrence of neovascularization at iris (NVI) and complications. RESULTS: Six eyes underwent adequate PRP before IVR but iris rubeosis still persisted. All eyes showed regression of NVI within 1 week after IVR. After TMC, mean IOP was significantly decreased from 37.9 mmHg preoperatively to 15.6 mmHg postoperatively (P < 0.001). Intraoperative hyphema was observed in four eyes. Thirteen eyes had controlled IOP (<21 mmHg) at last visit among which only one eye needed anti-glaucoma medication. Two eyes were considered as failure and needed further intervention. Visual acuity was maintained or improved in eight eyes. Recurrent NVI was not detected. All patients were symptom-free at last visit. Mean follow-up was 39 weeks. CONCLUSION: IVR is an effective treatment adjunctive to TMC for NVG. The occurrence of intraoperative complications was low and the short-term outcomes after trabeculectomy were favorable.
