You should remove the eyes from Davidson's after 24 hours and place them
into 70% alcohol until you are ready to process them. I have found this
to be the best way to get the best mouse eye sections. Cutting mouse
eyes can be very tedious if you need to see particular areas of the eye
that are at different levels. I recently had a study where all my
sections needed to show the optic nerve head. I found that there really
was no easy way to do this since each eye was different in size and I
couldn't find any standardization as to how deep to cut into it to show
that particular feature. I would recommend taking some practice eyes and
cutting those to ensure that your procedures and techniques are
suitable. I have never used an eyeball holder and I don't think that
they are necessary as long as you leave the optic nerve attached to the
eye. This helps with orientation.
I hope this helps.
