Actually, I have lectured several times for the OPS/ATPO/ASORN on comparative
anterior segment imaging techniques. Most recently, Mid Year meeting in
Chicago.

Now THAT sounds like an interesting Scientific Session topic... a comparison of
imaging modalities for the filtering angle blablabla.

Ah, the elusive "Gray zone" of the sulcus, sclera spur and beyond. UBM works
great, to a point. AS-OCT has it's shining moments. Gonio can make pretty
pictures. We're all looking for the Holy Grail- easy, high resolution images
of the iris and beyond. Something that can slice through pigment, yet
penetrate deep enough for the Glaucoma guys.
Sometimes, it's having the confidence to know that it's the technology failing
you, not your skills. Just as you get to the Angle and beyond, things start to
fall apart. UBM or at least 20MHz US works pretty well for the lens, at least
anteriorly, but depending on the eye, the depth of the AC, yadayadayada, really
getting enough information deep enough into the anterior posterior chamber is
tricky....
Don't even get me started about reproducible metrics!

Subject: [optimal] anterior heidelberg, viewing thru hazy cornea
We have a new anterior lens and module for the Hedelberg Spectralis at a second
site, but not much experience using it. As a photographer familiar with the
other Heidelberg functions, how much differnet is the anterior scanning
methodology? trying it a couple times, it seems that fixation can be an issue?
are there any optimal scan settings, ie ART levels, HS or HR?
basically I'm looking for some pointers, because an MD wishes to see the angle
for possible peripheral anterior synchiae, or a "mass blocking" which may be
causing a "malpositioned ACIOL in the chamber."
the trouble is, I don't know enough about the machines capability, especially
when the MD says she cannot see the angle due to a "hazy cornea."
any suggestions or comments would be appreciated.
Thanks,
John Head, CRA
