Lucentis Versus Mitomycin C During Glaucoma Surgery
Does a new add on (or adjunctive) therapy used in glaucoma surgery improve the success of trabeculectomy? Ranibizumab may offer benefit similar to mitomycin C in preventing epi-scleral fibrosis while avoiding the well known complications of mytomycin C which include late bleb leaks, hypotony and infection.

Experimental: A: Ranibizumab 0.5mg (0.05mL) injection
Ranibizumab 0.5mg (0.05mL) injection at end of trabeculectomy surgery. This intra-operative adjunct therapy was administered sub-conjunctivally 8-10mm posteriiorly to the limbus as an antifibrotic agent.
Ranibizumab 0.5mg (0.05mL)one injection in sub-tenon's at the conclusion of glaucoma surgery
Other Name: Lucentis
Active Comparator: B: Mitomycin C 0.4 mg/ml sponge
Mitomycin C 0.4 mg/ml soaked sponge applied to sclera (for up to 2 min) after flap is made during trabeculectomy surgery. This is the typical method used as an antifibrotic agent.
Drug: Mitomycin C 0.4 mg/ml
Mitomycin C 0.4 mg/ml applied with soaked pledget inserted in the sub-tenon's space during glaucoma surgery.
Other Name: MMC
This is an open-label, single center trial with two arms for patients who will undergo guarded filtration surgery to control glaucoma. The control will consist of patients randomly assigned to receive inter-operative mitomycin C 0.4 mg/ml which is applied in a standard fashion with a soaked pledget inserted in the sub-tenon's space during surgery. The study arm will consist of patients randomly assigned to receive a sub-tenon injection of Ranibizumab 0.5 mg/0.05mL with a 30 gauge needle on a tuberculin syringe at the termination of the surgery. No mitomycin C will be applied.
Post operative follow-up will consist of a minimum of 6 visits over a one year period.
