Purpose: To evaluate the effect of intravitreal injection of Bevacizumab on improving visual function in patients with Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION). Methods: In a prospective interventional case series, 11 eyes with vision loss due to (NAION) in less than 15 days of attack were studied. Visual acuity, perimetry and optic nerve head changes were evaluated 1 week post-intravitreal injection of 1.25mg/0.1 mL Bevacizumab. Results: 5 of patients had improved visual acuity. In all patients optic disc edema resolved either completely or remarkably in 1 week, but there was no significant change in perimetric values. Conclusion: This case series suggest that intravitreal injection of Bevacizumab may be beneficial in treatment of NAION.
