Note the interesting Visual Field Index (VFI) of 74%. Misguided misanthropists like Artes et al. have complained that the VFI stays near 100% in fields developing early diffuse loss (http://www.iovs.org/content/early/2011/04/04/iovs.10-6905.full.pdf+html). Clearly they don't know what they're talking about - even though the 74% here seem a bit of an underestimate.
Is this is one of those "perimetry athletes"...we've been hearing about? If they were wearing spandex and jogging on the spot during the test, that is a dead giveaway. Note however these athletes don't do so well at imaging (see here). Behold the flabby hamstring of structure-function science.
