BACKGROUND: To determine the safety and efficacy of intravitreal ranibizumab therapy before and after Ahmed tube insertion for open angle glaucoma (OAG) as a means of optimizing postoperative intraocular pressure (IOP) control. DESIGN: randomized, controlled trial PARTICIPANTS: OAG patients scheduled for Ahmed tube insertion, randomized to ranibizumab or control groups METHODS: Ranibizumab (0.5 mg in 0.05 ml) was administered intravitreally at 3 time points: 9 days prior to surgery, 1 month post-surgery, and 2 months post-surgery. Control patients underwent the same procedure without ranibizumab. MAIN OUTCOME MEASURE: Success at 6 months postoperatively was defined as IOP < 18 mmHg with no adjunctive medications, or IOP < 15 mmHg with one adjunctive medication. RESULTS: The study and control arms included 6 and 5 subjects, respectively, with 4 in each arm undergoing combined cataract surgery. In the ranibizumab arm, the pre- and postoperative IOP/medication usage was 21.0 ± 6.7 mmHg on 3.2 ± 1.5 medications and 14.7 ± 1.9 mmHg on 0.5 ± 0.8 medications, respectively. In the control arm, pre- and postoperative IOP/medication usage was 18.8 ± 3.8 mmHg on 2.8 ± 1.3 medications and 16.2 ± 3.6 mmHg with 1.8 ± 1.6 medications, respectively. Success was achieved in 83% of subjects in the ranibizumab group compared to 40% in the control group (2-tailed Fisher's exact test, p = 0.24). CONCLUSION: The findings from this small pilot comparative study suggest that intravitreal ranibizumab use may be a safe and potentially effective adjunctive treatment modality in improving success after Ahmed tube placement. © 2012 The Authors.
