Abstract

Purpose: To assess the duration of the effect of intracameral bevacizumab in patients presenting with rubeosis iridis and neovascular glaucoma (NVG). Methods: Retrospective analysis of 24 consecutive eyes of 24 patients with decompensated NVG (> 21 mm Hg) treated with a single intracameral injection of bevacizumab over a minimum follow-up of 6 months. The endpoint of the study was the need for retreatment due to recurrence of raised intraocular pressure (IOP). Secondary outcome was the course of visual acuity (VA) and IOP over 6 months. Results: A Kaplan-Meier calculation revealed a mean duration of the treatment effect of 23 +/- 4.4 days. Compared to mean IOP before treatment (26.3 mm Hg), decreases to 17.5 mm Hg at 1 week after treatment (p < 0.002) and to 17.1 mm Hg (p < 0.005) at 6 months following a single injection were seen. At 6 months, additional treatment was performed in 87.5% (n = 21) of eyes. VA remained stable or improved in 75% (n = 18) of all cases. Conclusion: The IOP-lowering effect of intracameral bevacizumab can be seen 1 week after the injection, but is limited to a period of approximately 3 weeks. However, the fast and effective response to intracameral bevacizumab injection opens a time window for additional treatments, which are often necessary. Copyright (C) 2011 S. Karger AG, Basel
