PATHOLOGY

Detailed explanation-1: -The sclera is the white outer coating of the eye. It is tough, fibrous tissue that extends from the cornea (the clear front section of the eye) to the optic nerve at the back of the eye. The sclera gives the eyeball its white color. The cornea and sclera are made of the same type of collagen fibers.

Detailed explanation-2: -The outermost layer is the fibrous tunic, which in this posterior region of the eye, consists of the sclera. The sclera is composed of densely woven collagenous fibers that make up the tough, white outer coat of the eye.

Detailed explanation-3: -The sclera, also known as the white of the eye or, in older literature, as the tunica albuginea oculi, is the opaque, fibrous, protective, outer layer of the human eye containing mainly collagen and some crucial elastic fiber.
