Conversion to aflibercept for XXXX unresponsive to ranibizumab or bevacizumab.

@entity2070 @entity1103
BACKGROUND: The purpose of this study was to determine if eyes with @entity1103 ( @entity1103 ) unresponsive to ranibizumab or bevacizumab would benefit from conversion to aflibercept. METHODS: This study was conducted as a retrospective chart review of subjects with @entity1103 unresponsive to ranibizumab and/or bevacizumab and subsequently converted to aflibercept. RESULTS: In total, 21 eyes from 19 subjects of mean age 62  15 years were included. The majority of subjects were male (63%). The median number of ranibizumab or bevacizumab injections before switching to aflibercept was six, and the median number of aflibercept injections after switching was three. Median follow-up was 5 months after the switch. Mean @entity2070 ( @entity2070 ) was 453.52  143.39 mm immediately prior to the switch. Morphologically, intraretinal cysts were present in all cases. Mean @entity2070 after the first injection decreased significantly to 362.57  92.82 mm (Wilcoxon signed-rank test; P<0.001). At the end of follow-up, the mean @entity2070 was 324.17  98.76 mm (P<0.001). Mean visual acuity was 0.42  0.23 logMAR just prior to the switch, 0.39  0.31 logMAR after one aflibercept injection, and 0.37  0.22 log-MAR at the end of follow-up. The final visual acuity was significantly better than visual acuity before the switch (P=0.04). CONCLUSION: Eyes with @entity1103 unresponsive to multiple ranibizumab/bevacizumab injections demonstrate anatomical and visual improvement on conversion to aflibercept.
