The sclera is a vascularized connective tissue structure of the [[eye]] composed of several types of [[collagen]] fibers, mainly collagen type I as well as [[elastin]], [[proteoglycans]] and [[glycoproteins]]. [[Blue sclera]] is caused by the slimness and transparency of the collagen fibers of the sclera that allow the visualization of the [[uvea]].

Overview

The sclera is a vascularized connective tissue structure of the eye composed of several types of collagen fibers, mainly collagen type I as well as elastin, proteoglycans and glycoproteins. Blue sclera is caused by the slimness and transparency of the collagen fibers of the sclera that allow the visualization of the uvea.
