Anatomy of the Eyeball: There is much more the eye than meets the… well, you know what I mean.
The eyeball contains two systems; the optic and visual system. The eyeball can also be broken down
by layers being; 1) fibrous layer, 2) vascular layer and 3) the Inner layer.
Fibrous layer: Figure below shows all three layers. The fibrous layer contains the sclera and cornea.
The vascular layer, Uvea (uvea,latin for grape) contains the choroid, the ciliary body and the iris. This
layer lies between the fibrous layer and inner layer and is sometimes called the middle layer. Finally,
what we are focused on for this article is the inner layer.
