P3D Ophthalmology and Geology using 3D

["nathan kreuter" <nathankreuter@xxxxxxxxxxx>]

Does any one know what type of stereo systems opthalmologists use?  I know 
that they do a lot of macro stereo photography of eyes because it allows 
them to see the anatomy of the eye very well.  I think it might be used 
before surgeries in order to look for potential complications. At any rate, 
I do know for a fact that these doctors do macro stereo work with at least 
2:1 magnification. I don't know whether they have a very specific camera for 
this or if they are using some type of a rail set up.  Does anyone have any 
factual knowledge about this (as opposed to blind speculation)?

I also know that people working in geology and cartography use large 
table-top viewers to look at pairs of 8"x10" aerial photographs in stereo. 
Nikon and a couple other companies make the viewers. Has anyone tried to use 
these to look at large stereo prints?
