Intravitreal Bevacizumab for Nonsubfoveal Choroidal Neovascularization Associated With Angioid Streaks

Abstract

To evaluate the effects of intravitreal bevacizumab injections in the treatment of nonsubfoveal choroidal neovascularization (CNV) associated with angioid streaks. Nonrandomized, interventional, prospective case series. Fifteen patients (15 eyes) affected by juxtafoveal or extrafoveal CNV secondary to angioid streaks were enrolled in the study. All patients underwent a complete ophthalmologic examination, including best-corrected visual acuity (BCVA) measurement on Early Treatment Diabetic Retinopathy Study (ETDRS) chart, optical coherence tomography (OCT), and fluorescein angiography (FA). The protocol treatment included a first injection, followed by repeated injections over a 12-month follow-up period on the basis of the detection of new hemorrhage on biomicroscopic examination, any type of fluid on OCT, or presence of leakage on FA. Mean changes in BCVA and proportion of eyes gaining at least 10 letters (2 ETDRS lines) at the end of the follow-up. Mean changes of central macular thickness (CMT) and extension to the fovea. Mean BCVA did not change throughout the follow-up period, being 0.2 ± 0.2 logMAR at baseline and 0.2 ± 0.3 logMAR at the 12-month examination. A functional improvement of at least 2 ETDRS lines was achieved by 5 eyes (33%), with 3 eyes (20%) gaining 3 lines. Mean CMT at baseline was 215 ± 13 μm and 225 ± 85 μm at the 12-month examination. Two eyes (13.3%) showed CNV extension to the fovea. Intravitreal bevacizumab injection can be a beneficial approach for the management of nonsubfoveal CNV secondary to angioid streaks over a 1-year follow-up.
