【 摘 要 】

Abstract Background Our aim was to examine the long term anatomical and functional outcomes in patients with refractory diabetic macular oedema (DMO) undergoing treatment switch from ranibizumab to aflibercept. Methods Retrospective review of patients with DMO undergoing treatment switch from ranibizumab to aflibercept at a single centre between 2015 and 2017. Primary outcomes were best corrected visual acuity (BCVA) and central macular thickness (CMT). Results 57 eyes from 44 patients were included. Following switch to aflibercept, median (IQR) BCVA improved to 73 (64–77) letters at 3 months (p = 0.0006), to 73 (61–78) letters at 6 months (p = 0.0042), to 73 (65–77) at 9 months (p = 0.0006), and to 73 (63–75) letters at 18 months (p = 0.0444). At 36 months following switch, 12 eyes had gained > 10 letters, 5 eyes had gained 5–9 letters, 25 remained stable (± 5 letters), 7 eyes lost 5–9 letters and 8 eyes lost > 10 letters. A significant reduction in CMT at all trimesters following treatment switch was found except at month 24. Conclusions We provide real world data suggesting a sustained anatomical and functional benefit of switching from ranibizumab to aflibercept in the treatment of refractory DMO.
