Hi Group, (Posted Thursday morning 11.29.12 - After Powerball, 8:38 am, EST,
New York)
We have a Cirrus 4000, with the 6.2 software in our office.
Our practice for EDI patients has been the following.
We capture a 5 Line Raster Scan on the area in question.
Then, we engage the HD 5 Line Raster on the same area, keep the 5 line function
in play,
and engage the EDI function on the bottom of the screen. We raise up the scan
beam just
one thickness using the adjustment function, and not the mouse's 'Wheel
Function' of the
retinal layers, because, the EDI may need more room in the OCT capture window,
to scan in
the choroid. We then run that 5 line function, and save it. The saving takes
about 9 seconds.
Only in a few cases, have we elected to chose the single line EDI function (as
with Peter Hay),
though, I am not quite sure of it's relevance for the single scan use yet.
Perhaps it uses all
of the Cirrus's energy to perform the EDI scan on just a single line, though, I
have to refer to
my CAS specialist for further details. Or, just wait till Mike Turano chimes
in on this original
thread.
Of another note, I have to get more aquainted with placing the measurement
curser on
the correct interfact of the choroid/sclera of the finished EDI scan. Our
practice thus far, is
to measure from that surface (which takes a bit of learning to do), to the
posterior surface
of the RPE layer.
Denise, do you want me to email you some images of a 5 Line, and of an EDI on
the same
patients so you can see the difference?
Get a hold of me off list.
Good Luck All,
Jim
