Intravitreal Bevacizumab for Nonsubfoveal Choroidal Neovascularization Associated With Angioid Streaks: 3-Year Follow-up Study.
American Journal of Ophthalmology 2016 May
PURPOSE: To assess the effects of intravitreal bevacizumab injections in the treatment of nonsubfoveal choroidal neovascularization (CNV) associated with angioid streaks (AS) in a 3-year follow-up study.
DESIGN: Noncomparative, interventional, prospective case series.
METHODS: Eighteen patients (18 eyes) with juxtafoveal/extrafoveal CNV secondary to AS were recruited. All patients underwent a complete ophthalmologic examination, including best-corrected visual acuity (BCVA) measurement on ETDRS chart, optical coherence tomography (OCT), and fluorescein angiography (FA). The protocol treatment included a first injection, followed by repeated injections on the basis of detection of new hemorrhage, any type of fluid on OCT, and/or presence of FA leakage. Primary outcome measures were final mean changes in BCVA and proportion of eyes with 10 ETDRS letters improvement. Secondary outcomes were mean changes of central macular thickness (CMT) and foveal involvement.
RESULTS: After a mean BCVA stabilization over the first year, a statistically significant BCVA worsening was registered at the 24-month (72.8 ± 10.0 ETDRS letters, P = .03) and 36-month examinations (65.8 ± 15.0 ETDRS letters, P = .02) in comparison with the 1-year visual outcomes (80.1 ± 5.4 ETDRS letters); lastly, a substantial stabilization in the BCVA was observed at 36 months in comparison with the baseline value (77.9 ± 10.0 ETDRS letters, P = .22). Two eyes (25%) with juxtafoveal CNV and no eye with extrafoveal CNV experienced a 10-letter improvement at the 3-year examination. Mean CMT at baseline was 220 ± 15 μm and 235 ± 66 μm at 36 months (P = 1.00). During the first and second years of follow-up, 5 juxtafoveal CNVs and 3 extrafoveal CNVs showed foveal involvement.
CONCLUSIONS: Intravitreal bevacizumab can be effective in the management of nonsubfoveal CNV secondary to AS, although monthly monitoring is required to control CNV recurrence or progression.
