Intravitreal Ranibizumab Treatment of Macular Choroidal Neovascularization Secondary to Angioid Streaks: One-Year Results of a Prospective Study.
Retina(2010)
摘要
Purpose: The purpose of this study was to evaluate the efficacy of intravitreal ranibizumab in eyes with macular choroidal neovascularization secondary to angioid streaks.Methods: A prospective interventional case series was conducted on eyes with macular choroidal neovascularization, secondary to angioid streaks, treated by repeated injections of intravitreal ranibizumab (0.5 mg) and completing a follow-up time of 1 year. The outcome measures were best-corrected visual acuity, greatest lesion height as evaluated by optical coherence tomography, and lesion size as assessed by fluorescein angiography.Results: Over a 16-month period, we treated 15 consecutive eyes. The average number of injections was 7.1 +/- 6 0.5. Mean best-corrected visual acuity was improved from 20/100 to 20/50 (P = 0.006). Best-corrected visual acuity either improved or stabilized in 14 eyes (93.3%). At baseline, 3 of the 15 eyes (20%) had a best-corrected visual acuity of >= 20/50 compared with 10 eyes (66.7%) at the end of the first year. Fourteen eyes (93.3%) presented reduction in greatest lesion height and stabilization or reduction in lesion size. The mean greatest lesion height was decreased from 377.3 +/- 139.7 mu m to 270.2 +/- 88.6 mu m (P < 0.001).Conclusion: Intravitreal ranibizumab is highly effective in improving or stabilizing vision and lesion morphology in patients with macular choroidal neovascularization secondary to angioid streaks.
