The Heidelberg uses light to make the image and if you and see in due the opacity you will not be able to get an image. The best option would be to use a UBM ultrasound. G.

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
