INTRODUCTION:
Our paired eyes are located in sockets of the skull called orbits. The adult human eye ball is nearly a spherical structure. The wall of the eye ball is composed of three layers.

The external layer is composed of a dense connective tissue and is called the sclera.
The anterior portion of this layer is called the cornea.
The middle layer choroid contains many blood vessels and looks bluish in colour.

Choroid layer is thin over the posterior to 2/3rd of the eyeball, but it becomes thick in the anterior portion to form the ciliary body.

The ciliary body itself continues forward to form a pigmented and opaque structure called the Iris which is the visible coloured portion of the eye.

The eye ball contains a transparent crystalline lens which is held in place by ligaments attached to the ciliary body.

In front of the lens the rounded by the Iris is called the pupil.
The diameter of the Pupil is regulated by the muscles fibres of iris.
