Seeing From a Sheep's Perspective... sort of

This is the sheep eye that we got to dissect once it was cleaned of all of the fat tissue and as much of the external muscles that Amelia could cut off. You can see the cornea, sclera, and the nub of the optic nerve. 

We cut it open in have to make anterior and posterior hemispheres (which was tricky because the sclera is quite tough to puncture and cut through since it is meant to hold the eye's shape).

Here we have taken out the vitreous humor and the lens and we noticed that even though it is jelly like, they both have a lot of structure to them. The lens was also very hard but still has a little bit of give to it because it does need to be able to change shape and focus our vision on stuff.

Here are the two hemispheres completely separate. On the left you can see the vitreous humor filling the eye and the slightly yellow orb is the lens. On the right you can see the layer of the retina on the choroid and the green color of the tapedum lucidum which is something humans don't have.

For this we have carefully scraped the retina off of the choroid (black layer) and then peeled part of the choroid off of the sclera to expose the 3 layers. Notice how the retina is attached at one point because that is where the optic nerve is and creates our blind spot.

This is an outer view of the eye with the clouded cornea cut out to expose the iris and the rectangular pupil.
