Eye Dissection Photos
The
dissection photos on this page were taken as I dissected the
cow's eye according to the directions given to the students.
I kept the photos on a high-quality resolution so they would be
clear, but it also means they may take a moment or two to
download. Please be patient!
More photographs and a video can be seen at the link below.
The video is a helpful tutorial to watch before you do your
dissection. The eye on the video will look different
because it is not preserved.

After
removing the fat and extra muscle, the eye should look clean.
Cut the eye
in half so that you have a front half and a back half.
The
pupil/cornea will be on the front half.
This is the
front half of the eye after the iris has been lifted out by
hand.
In this
photo, the cornea is seen on the left.
On the right
is the circular iris, and the horizontal opening is the pupil.
The
jelly-like vitreous humor is on the left and the lens is on the
right.
The back of
the eye reveals the colorful tapetum which reflects light back
into the eye.
The retina
is usually spread out, but is seen here as a clump of tissue
because the vitreous humor has been removed.
The point of
attachment at the back of the eye is the beginning of the optic
nerve. |
