FIGURE 22.7 | Posterior Eyeball: Sclera, Choroid,

Optic Papilla, Optic Nerve, Retina, and Fovea

(Panoramic View)

This higher-magnification illustration shows a section of the retina in the

posterior region of the eyeball. Visible are the pigmented choroid (7) with its
blood vessels and the connective tissue layer sclera (8). A shallow depression in
the retina is the fovea (5), which primarily consists of the light-sensitive cones
(6). The rest of the retina contains the rods and cones (3), the different cell and

fiber layers of the retina, and fibers of the optic nerve (1) that converge
posteriorly in the eyeball to form the optic papilla (2) and the optic nerve (4),
which exits the eyeball.

The specific cell and fiber layers that constitute the rest of the photosensitive
retina are illustrated and described at a higher magnification in Figures 22.8 and

22.9.
