Denice,
I think this falls within the sampling range. The cut-off has to be a
single number: 58 microns is red and 59 is yellow. Note the other
values obtained on the two scans:
Sector NS: 58 59
N : 86 85
NI: 88 79
TI: 120 119
T : 56 57
TS: 107 115
Think of a fasting glucose test:
Glucose level 125 Patient: "I have impaired glucose tolerance."
Next test:
Glucose level 126 Patient: "Oh my God, I have diabetes!"
Take the numbers and colors with a grain of salt: you can be a little
or a lot into the red zone.

Somewhat alarmed to see today that two separate RNFL scans, seemingly
reasonable well centered, can show such different results based on
where the instrument choses to segment.
A very slight, nearly inperceptable adjustment on my part took this
patient out of the red zone and back into borderline.
Your thoughts? ART set at 16. Too much? Too little?
