Purpose:
To evaluate the efficacy of switching from intravitreal ranibizumab to intravitreal aflibercept in choroidal neovascularization secondary to angioid streaks.
Design:
Multicenter retrospective interventional case series.
Methods:
Patients previously treated with intravitreal ranibizumab with at least 12-month follow-up (M12) after switching (M0) to intravitreal aflibercept. Switch to intravitreal aflibercept was decided in cases of refractory or recurrent choroidal neovascularization. Primary endpoint: Change of best-corrected visual acuity using the Early Treatment Diabetic Retinopathy Study letters. Secondary endpoints: Mean change of central macular thickness, absence of intraretinal/subretinal fluid on spectral domain optical coherence tomography and the percentage of eyes with absence of leakage on fluorescein angiography.
Results:
Fourteen eyes of 13 patients were included. Mean best-corrected visual acuity was 65.0 ± 21.03 letters at M0 and 63.5 ± 17.30 letters at M12 (p = 0.5). Secondary endpoints: Mean central macular thickness was 344 ± 194.65 µm at M0 and 268 ± 79.97 µm at M12 (p = 0.008). Absence of intraretinal/subretinal fluid was observed in 71%. Fluorescein angiography (nine eyes) showed absence of leakage in 77% (seven eyes).
Conclusion:
Switching from intravitreal ranibizumab to intravitreal aflibercept represents a therapeutic option in patients with refractory or recurrent choroidal neovascularization secondary to angioid streaks.
