RESUMEN
PURPOSE: To evaluate the efficacy of intravitreal bevacizumab in the treatment of choroidal neovascularization (CNV) secondary to angioid streaks. METHODS: We conducted a prospective study in the ophthalmology department of Hassan II university hospital in Fez, including 12 eyes of 7 patients with CNV associated with angioid streaks. We injected 8 eyes with bevacizumab 1.25mg; best corrected visual acuity (BCVA), fundus examination, fluorescein angiography and optical coherence tomography were performed and analyzed for all patients before and after treatment. The goal of the study was to determine the percentage of patients with stabilization or improvement in BCVA and decreased central macular thickness. RESULTS: Visual acuity on admission was <1/10 in 75% of patients. We injected 8 eyes with anti-VEGF, whereas abstention was appropriate for 4 eyes with disciform scarring. The average number of bevacizumab injections was 4.3±1.3 over a mean follow-up of 14.57 months±5.3. After treatment, BCVA was <1/10 in 12.5% of cases, between 1/10 and 5/10 in 50% of cases, and in 37.5% of patients, it was ≥5/10. Mean central macular thickness decreased from 424.25±137.03µm on admission to 255.75 microns±50.14 post-treatment (P=0.005). CONCLUSION: Intravitreal bevacizumab is a promising and effective treatment option for the management of CNV associated with angioid streaks, with the requirement however of early treatment and extended follow-up.
