 Alright, we are going to show how to cut a cow eye. So first, always keep the eye in the tray. Do not hold it in your hand when you're cutting, this is just basic safety. And here's the cornea on the front, there's the sclera, and then this in the back, that's your optic nerve. You can use the cornea as a guide to cutting it, so I'm going to start up here on the top, make an incision, and then I'm going to work my way around the cornea. Then that jelly-like fluid that comes out of it is the vitreous humor. This thing in here that looks like a mentos is the lens, and you can pull that out of the fluid, it's a relationship to the cornea, there's the lens. And behind this, the stark stuff is the iris, just removing all the vitreous fluid. And now you can see the iris, and the hole in the middle is the pupil. On the back side, we have this light-colored stuff, this is the retina, and notice how thin it is, and you can peel it away, and the blue stuff underneath is a reflective surface called the topetum. There's a spot that won't really peel away, right there, that is where the blind spot is, or where the optic disc is. That's where the nerve connects to the cells on the retina, and that's pretty much all there is to the eye.
