PURPOSE: To evaluate 6-month and 1-year outcomes of every-8-weeks (Q8W) aflibercept in patients with resistant neovascular age-related macular degeneration (AMD). DESIGN: Retrospective, interventional, consecutive case series. METHODS: Retrospective review of patients with resistance (multiple recurrences or persistent exudation) to every-4-weeks (Q4W) ranibizumab or bevacizumab that were switched to Q8W aflibercept. RESULTS: Sixty-three eyes of 58 patients had a median of 13 (interquartile range [IQR], 7-22) previous anti-vascular endothelial growth factor (anti-VEGF) injections. At 6 months after changing to aflibercept, 60.3% of eyes were completely dry, which was maintained up to 1 year. The median maximum retinal thickness improved from 355 μm to 269 μm at 6 months (P < .0001) and 248 μm at 1 year (P < .0001). There was no significant improvement in ETDRS visual acuity at 6 months (P = .2559) and 1 year follow-up (P = .1081) compared with baseline. The mean difference in ETDRS visual acuity compared to baseline at 6 months was -0.05 logMAR (+2.5 letters) and 0.04 logMAR at 1 year (-2 letters). CONCLUSION: Sixty percent of eyes with resistant AMD while on Q4W ranibizumab or bevacizumab were completely dry after changing to Q8W aflibercept at the 6-month and 1-year follow-ups, but visual acuity did not significantly improve. Only a third of eyes needed to be switched from Q8W to Q4W aflibercept owing to persistence of fluid; Q8W dosing of aflibercept without the initial 3 monthly loading doses may be a good alternative in a select group of patients who may have developed ranibizumab or bevacizumab resistance.

Abstract

PURPOSE: To evaluate 6-month and 1-year outcomes of every-8-weeks (Q8W) aflibercept in patients with resistant neovascular age-related macular degeneration (AMD). DESIGN: Retrospective, interventional, consecutive case series. METHODS: Retrospective review of patients with resistance (multiple recurrences or persistent exudation) to every-4-weeks (Q4W) ranibizumab or bevacizumab that were switched to Q8W aflibercept. RESULTS: Sixty-three eyes of 58 patients had a median of 13 (interquartile range [IQR], 7-22) previous anti-vascular endothelial growth factor (anti-VEGF) injections. At 6 months after changing to aflibercept, 60.3% of eyes were completely dry, which was maintained up to 1 year. The median maximum retinal thickness improved from 355 μm to 269 μm at 6 months (P < .0001) and 248 μm at 1 year (P < .0001). There was no significant improvement in ETDRS visual acuity at 6 months (P = .2559) and 1 year follow-up (P = .1081) compared with baseline. The mean difference in ETDRS visual acuity compared to baseline at 6 months was -0.05 logMAR (+2.5 letters) and 0.04 logMAR at 1 year (-2 letters). CONCLUSION: Sixty percent of eyes with resistant AMD while on Q4W ranibizumab or bevacizumab were completely dry after changing to Q8W aflibercept at the 6-month and 1-year follow-ups, but visual acuity did not significantly improve. Only a third of eyes needed to be switched from Q8W to Q4W aflibercept owing to persistence of fluid; Q8W dosing of aflibercept without the initial 3 monthly loading doses may be a good alternative in a select group of patients who may have developed ranibizumab or bevacizumab resistance.
