Results of switchback from ranibizumab to aflibercept in patients with exudative age-related macular degeneration. | LitMetric

AI Article Synopsis

  • - The study aimed to evaluate the effectiveness of switching back from aflibercept to ranibizumab in patients with exudative age-related macular degeneration (AMD) who did not respond well to initial aflibercept treatment.
  • - Eleven patients were involved, with outcomes measured in injection intervals, visual acuity, and central retinal thickness; some showed improvements in these areas after the switchback.
  • - Results indicated that while 36.4% had extended injection intervals after switching back, nonresponders to aflibercept did not benefit from this change.

Article Abstract

Purpose: Intravitreal injection of anti-VEGF drugs has become standard therapy for patients with exudative age-related macular degeneration (AMD). However, some patients do not exhibit sufficient response to the drugs for suppression of choroidal neovascularization activity. We investigated the efficacy of switchback from ranibizumab to aflibercept in patients with AMD who could not achieve further benefit beyond initial therapy of aflibercept injection.

Methods: Eleven eyes of eleven patients were included in this study. Two patients were nonresponders, and nine exhibited tachyphylaxis to aflibercept. All patients received three monthly injections of ranibizumab as an initial phase of switching and received aflibercept as a switchback drug. We investigated changes in injection interval, visual acuity, and central retinal thickness.

Results: In four patients (36.4%), injection interval was extended. The interval was 6.73 weeks before switch and 9.27 weeks after switchback (=0.96). LogMAR visual acuity was 0.22 before switch and 0.24 after switchback (=0.62). Central retinal thickness was 306.8 µm before switch and 256.1 after switchback (=0.13). In all patients who were nonresponders to aflibercept, injection interval could not be extended.

Conclusion: A switchback from ranibizumab to aflibercept may be beneficial in some patients with AMD who exhibit tachyphylaxis to aflibercept.
