I would like to know if anyone uses a dye or ink to mark certain structures
at trimming that will stay in place and be visible after processing (at
cutting).  I am trimming primate eyes and would like to mark the macula (and
fovea) or the outside of the eye where the macula is so that it would be
easier to obtain at cutting.  I think I need a color other than black.  Can
anyone suggest anything?  Does anyone know of a dye or ink that can be
applied after processing just prior to embedding?  Thanks in advance for
your help.
