In an NIH-supported clinical trial comparing three drugs for diabetic macular edema (DME), Eylea (aflibercept) provided greater visual improvement, on average, than did Avastin (bevacizumab) or Lucentis (ranibizumab) when vision was 20/50 or worse at the start of the trial.

Brain Training May Bolster Visual Attention

If a study participant were instructed to pay attention to “scenes” and he was attending well, he would be shown the top image as a reward. As his attention lapsed, the middle and bottom images would be shown. The face in the photograph is that of the study’s first author, Megan deBettencourt, a doctoral candidate at the Princeton Neuroscience Institute.
