Ans.A. Collagen type I
The sclera, also known as the white of the eye, is the opaque, fibrous, protective, outer layer of the human eye containing mainly collagen and some elastic fiber.
Human scleral tissue contains approximately 50% collagen by weight, consisting predominantly of type I collagen.
There is little or no evidence for the presence of substantial quantities of type II, type III or other collagen types.
