This figure shows a side view of the internal anatomy of the eyeball. The eyeball has an outer white covering. At the front of the eye, the white tissue transitions into a clear tissue that covers the blue-colored part of the eye. The back of the eye has a tubelike projection containing yellow tissue and blood vessels. Letter A indicates yellow-colored tissue that lines the inside surface of the back of the eye. The yellow-colored tissue runs from the back of the eye up along the inside of the tubelike projection. Letter B indicates a clear disc near the front of the eye, just behind the structure that gives the eye its blue color. Letter C indicates the blue-colored structure of the eye, which surrounds a black hole. Letter D indicates the tubelike projection at the back of the eye.
