After our system was upgraded we saw a significant improvement with
tracking and scan speed when using the 200kHz mode. Performance after the
upgrade has been good so far, we are pretty happy with it about 1 month in.
I've only noticed some minor issues with the enhance/polarization
(sometimes needs to be adjusted manually) as well as some segmentation
errors on the new 15x15 and HD12mm scans. We did need to provide a current
IRB in order to go forward with the upgrade.

Eric,
Thanks for getting back to me so quickly. We have the new upgrade
scheduled for March 1st and I just want to make sure it's not going to be a
mistake. The tracking is so bad at this point that the thought of doing a
study which needs consistency is daunting. We are going to try to do 6x6
which I can track most of the time. Originally we wanted 15x9 montage but
the tracking was almost impossible for consistency sake. Thanks again for
your help.

Sara,
I’m not quite sure how tracking could get worse. When the PlexElite
works, it gives beautiful images, but I constantly have trouble with
tracking especially on the 3 mm scan, with hi-res tracking, and 15 x 9 mm
montage scan. Most of my 15 x 9 mm montage scans are done with the tracking
off, giving a less than ideal scan but I cannot get the scan to finish if I
leave tracking on, as it times out before the scan can finish. We are
looking at getting the next software version as well, but my understanding
is that it would have to be under the auspices of an IRB since I don’t
believe it is FDA approved, but I could be wrong. I have been known to be
wrong often, J

Thanks Paul for your advice. We haven't started the study yet and it is
an inhouse one. Heard the update might cause problems. Fishing for
someone's experience with the new software. BTW are you talking about OCT
A with the Optovue? We' re having trouble uploading for DRCR. Could this
be a software upgrade issue?
Thanks again,
Sara

Hi Sara,
If you are already using your Plex Elite for research & do an upgrade
make sure you update the reading center of the changes (if you're
submitting to a RC). I'm not a user & not sure if the new version addressed
any tracking issues but I do some work importing OCTA images for one of the
RCs & we originally had issues opening files from a site we previously had
no problems with until we found out the site was using the newer version.
You might want to contact Zeiss to find out what that new version has
changed & any other specific questions you're concerned about.
Good luck

Is anyone using the Zeiss Plex Elite for research? We're planning on
doing an upgrade to version 2.1 and need to know if this is going to cause
problems with tracking. A conversation about your experience would help me
move forward in making important decisions. Feel free to contact me offline
when you have a few minutes.
My thanks to Brice Citser for reaching out so far.
