Background and Objective: To report on preliminary findings of adjunctive subconjunctival bevacizumab (SCB) injections in patients undergoing Ahmed valve implantation (AVI) (New World Medical, Rancho Cucamonga, CA). Patients and Methods: The study was approved by the institution’s ethics committee. Patients were prospectively recruited during a 1-month period and randomized to receive AVI with postoperative SCB (days 1 and 7, n = 7) or AVI without SCB (n = 6). Results: Baseline intraocular pressure (IOP) in the treatment (AVI+SCB) group was 19.4 ± 8.6 mm Hg, whereas baseline IOP in the control (AVI) group was 32.1 ± 17.7 mm Hg ( P = .119). Final IOP was 13.8 mm Hg (n = 7) for the treatment group and 12.7 mm Hg for the control group (n = 5, P = .790). One eye in the control group required further glaucoma intervention at day 45 and was considered a failure. The pre-massage postoperative IOP was significantly lower for the treatment group only at day 45 (16.1 vs 26.0 mm Hg, P = .012). Mean post-massage IOP was significantly lower in the treatment group at day 15 (11.28 vs 17.16 mm Hg, P = .004), day 30 (11.28 vs 20.83 mm Hg, P = .015), and day 45 (12.16 vs 21.33 mm Hg, P = .001), and similar at month 3. Mean change in bleb area was 11.4 mm 2 in the treatment group and −0.4 mm 2 in the control group ( P = .036 and P = .361, respectively, Student’s paired samples t test). Conclusion: Bevacizumab was associated with a less aggressive hypertensive period as measured by post-massage IOP measurements, postoperative glaucoma medications, and cross-sectional bleb area by ultrasound. Further prospective studies are needed to better understand the utility of SCB at the time of AVI surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
