ABSTRACT
PurposeTo report the visual and anatomic outcomes in eyes with macular oedema (MO) secondary to central retinal vein occlusion (CRVO) that were switched from either intravitreal bevacizumab or ranibizumab to intravitreal aflibercept.MethodsTwo-center retrospective chart review. Eyes with MO secondary to CRVO that received a minimum of three intravitreal injections of bevacizumab or ranibizumab and were switched to intravitreal aflibercept for persistent or recurrent MO not responding to either bevacizumab and/or ranibizumab.ResultsIn all 42 eyes of 42 patients were included in the study. The median visual acuity before the switch was 20/126, 1 month after the first injection of aflibercept 20/89 (P=0.0191), and at the end of the follow-up 20/100 (P=0.2724). The median CRT before the switch was 536 µm, 1 month after the first injection of aflibercept 293.5 µm (P=0.0038), and at the end of the follow-up 279 µm (P=0.0013 compared to before the switch). The median number of weeks between injections before the switch was 5.6 and after the switch was 7.6 (P<0.0001).ConclusionConverting eyes with refractory MO due to CRVO to aflibercept can result in stabilization of the vision, improved macular anatomy, and extension of the injection interval.
