Remember, it's not only resolution you are looking for but axial and transverse
DEPTH. Axial Depth of imaging is crucial beyond the posterior iris which is
more or less where the OCT systems stop.
I use the Heidelberg Spectralis AS-OCT regularly. Makes nice pictures- no time
or effort put into developing solid metrics
Default to the Optovue AS-OCT. Love it for anterior imaging tasks such as
Iris Cyst, Iris Atrophy.
BOTH systems fail you in the "gray zone". What all of the Glaucoma people
want. The depth of imaging like the UBM, with the resolution of an OCT based
system. Optovue's metrics are reasonable but would not bank on measuring
angles with this.
The Nidek Gonioscope shows real promise, but not yet USA FDA approved. We'll
probably NEVER get our Resident's to learn gonioscopy if we had this
instrument.... LOL

Amazing image Mike. I loved this SD oct system so much too.. Too small a market
to keep it viable. Cirrus AS OCT doesn't have a camera that focuses on the
anterior structures.
We use our visante to look at tubes and all sorts of pathology that requires
careful placement of the scan over lesions.
This necessitates the ability to see the anterior segment well and in detail,
clearly and in focus. Just guessing with the CIRRUS when we tried it.
How does the Heidleberg AS OCT module look? Can anyone describe its
functionality?

Subject: [optimal] Visante OCT calibration failing
Hi all,
Our beloved visante OCT is over half a decade beyond support but has been an
invaluable and reliable system for us.
Recently the calibration has failed and scanning is now disabled. We get an
error message to contact zeiss service.
Of course it isn't supported anymore. I understand and am not disputing this
position at all. Fair enough she is super ancient.
Has anyone had this system fail calibration and had some genius solution to
revive it?
