The sclera (from the Greek skleros, meaning hard), also known as the white of the eye, is the opaque, fibrous, protective, outer layer of the eye containing collagen and elastic fiber.n the development of the embryo, the sclera is derived from the neural crest. In children, it is thinner and shows some of the underlying pigment, appearing slightly blue.
The sclera is opaque and appears white due to the high (68%) water content and disorderly array of transverse and oblique collagen (75%) fibers that make up its coat. (Figure1). It is this same array that lends the strength and rigidity to the globe despite its constant movement and pull from the extraocular muscles.
