The retina is a nearly transparent sheet of tissue continuous with the optic nerve in the back of the eye and extending forward as the inner lining of the eyeball.

This is a strong layer of tissue that covers nearly the entire surface of the eyeball. choroid. Pegasus2 - 38 minutes ago. Black-pigmented layer under the Sclera that prevents the internal reflection of light rays. they can work with with the other layers of the eyes. The inner layer of the wall of the eye consists of the retina, which contains the visual receptor cells (photoreceptors). The conjunctiva is the outer lining of the eye and it can swell over time causing a condition known as conjunctivochalasis.

Eyeball,is a hollow sphere that composed three tunics,or coats, and its interior is filled with fluids called humors that help to maintain its shape. Explanation: Tunics of the eyeball. The eye is cushioned within the orbit by pads of fat. Just behind the iris, the surface of the ciliary body is thrown into folds known as ciliary processes.
