    Abstract:

    To determine the safety and efficacy of intravitreal ranibizumab therapy before and after Ahmed tube insertion for open-angle glaucoma as a means of optimizing postoperative intraocular pressure control.Randomized, controlled trial.Open-angle glaucoma patients scheduled for Ahmed tube insertion, randomized to ranibizumab or control groups.Ranibizumab (0.5 mg in 0.05 mL) was administered intravitreally at three time points: 9 days prior to surgery, 1 month post-surgery and 2 months post-surgery. Control patients underwent the same procedure without ranibizumab.Success at 6 months postoperatively was defined as intraocular pressure <18 mmHg with no adjunctive medications or intraocular pressure <15 mmHg with one adjunctive medication.The study and control arms included six and five subjects, respectively, with four in each arm undergoing combined cataract surgery. In the ranibizumab arm, the preoperative and postoperative intraocular pressure/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, preoperative and postoperative intraocular pressure/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 with 40% in the control group (two-tailed Fisher's exact test, P = 0.24).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.
