The sclera is the part of the eye commonly known as the âwhite.â It forms the supporting wall of the eyeball, and is continuous with the clear cornea. The sclera is covered by the conjunctiva, a clear mucus membrane that helps lubricate the eye. It is thickest in the area surrounding the optic nerve.
sclera (sklerÂ´É) , n the opaque, fibrous, protective layer of the eye containing collagen and elastic fibers. It is commonly known as the white of the eye. Because the sclera is thinner in children, some of the underlying eye pigment is visible, making the eye appear slightly bluish. In older adults, fatty deposits on the sclera make it appear slightly yellowish.
