AIM: To determine real life clinical outcomes in poorly responsive and treatment-naïve neovascular age related macular degeneration (nvAMD) patients using bimonthly fixed dosing aflibercept regimen.
METHODS: This was a retrospective study of 165 eyes with nvAMD started on aflibercept at Southampton Eye Unit between June 2013 and June 2014. Patients were either switched from pro re nata (PRN) ranibizumab/bevacizumab due to poor response (107 eyes), or treatment-naïve (58 eyes). Patients initially received 3-monthly intravitreal aflibercept injections followed by 2-monthly fixed doses. Clinic visits were scheduled at month 0, 4, 10 and 12. Mean change in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) from baseline were assessed using the Wilcoxon signed-rank test. The proportion of patients maintaining BCVA (<15 letters loss) at 12mo was also evaluated.
RESULTS: Mean BCVA change at month 12 was +3.29 and +4.67 letters in the switched and naïve aflibercept groups respectively (P<0.01). BCVA was maintained in 95.3% of switched and 96.6% of naïve patients. CRT at month 12 showed a decrease of -6.16 µm in the switched group and -35.36 µm in the naïve group (P<0.01). Patients previously treated with ranibizumab/bevacizumab had on average received 7.4 ranibizumab/bevacizumab injections over 12.6mo, attending 10 clinic visits. The fixed dosing aflibercept regimen required an average of 7.1 injections (naïve group), 7.5 injections (switched group) and 4 clinic visits per year.
CONCLUSION: Fixed bimonthly aflibercept is effective in both treatment-naïve and poorly responsive nvAMD patients. Adopting a fixed dosing regimen can reduce patient burden without compromising on outcomes. 相似文献
Purpose: The purpose of this study was to evaluate the influence of serous retinal detachment (SRD) on the outcome of intravitreal ranibizumab (IVR) therapy in diabetic macular oedema (DME).Materials and methods: Fifty-one eyes with cystoid macular oedema (CME) and SRD (study group) and 57 eyes with only CME (control group) that received pro re nata (PRN) IVR injections during a 6-month period were retrospectively evaluated. The outcome measures included changes in the central macular thickness (CMT) and best corrected visual acuity (BCVA) and injection numbers.Results: The mean initial CMT in the study and control groups was 467?±?101 and 440?±?89?µm, respectively. The mean BCVA in the study and control groups was 0.75?±?0.38 and 0.59?±?0.36 logarithm of minimal angle of resolution (LogMAR), respectively (p?=?0.010). The study group received a mean of 2.2?±?0.92 injections, whereas the control group received a mean of 2.54?±?0.9 injections. The decrease in CMT was greater, but not significantly greater, in the study group than in the control group.Conclusion: The presence of SRD resulted in a less favourable visual acuity (VA) outcome with IVR. Disruption of the ellipsoid zone and abnormality of the foveal avascular zone at the baseline examination were correlated with a lower VA. Both of the pathologies occurred more frequently in the SRD group. 相似文献
结果:治疗前两组患者眼压无差异(46.2±9.41mmHg vs 49.1±10.15mmHg,P>0.05),治疗后1wk,1、6mo A组患者眼压均低于B组(P<0.05)。治疗后6mo,A组视力、眼压控制率(95%)、新生血管消退情况(91%)均优于B组(P<0.05),但随访期间两组患者并发症发生率无差异(P>0.05)。
