Abstract

Purpose To assess the short-term safety and efficacy of intravitreal injection of bevacizumab for iris neovascularization (INV). Design Noncomparative, interventional case series. Methods Intravitreal bevacizumab was injected in seven eyes of five patients with INV that was associated with proliferative diabetic retinopathy (PDR). The main outcome measurements were visual acuity, intraocular pressure (IOP), and regression of INV by fluorescein angiography before and one week, one month, and two months after injection. Results Regression of INV was confirmed in all eyes (100%) from one week after injection. Repeated injections stabilized the recurrence (two eyes; 29%) that was observed two months after the initial injection. The visual acuity remained stable or improved, and the intraocular pressure was controlled in six eyes (86%) throughout the follow-up period. No inflammation or complications were observed. Conclusions Intravitreal injection of bevacizumab may be an effective and safe alternative for patients with INV that is refractory to conventional treatments.
