The sclera is the dense connective tissue of the eyeball that forms the "white" of the eye. It is continuous with the stroma layer of the cornea. The junction between the white sclera and the clear cornea is called the limbus.
The sclera ranges in thickness from about 0.3 millimeter (mm) to 1.0 mm. It is composed of fibrils (small fibers) of collagen that are arranged in irregular and interlacing bundles. The random arrangement and interweaving of these connective tissue fibers are what account for the strength and flexibility of the eyeball.
The sclera is relatively inactive metabolically and has only a limited blood supply. Some blood vessels pass through the sclera to other tissues, but the sclera itself is considered avascular (lacking blood vessels).
