Its opaque, white appearance is due to the irregular arrangement of collagen fibers that scatter light rather than transmit it. In contrast, the sclera prioritizes protection and structural support over optical clarity.
Understanding the Sclera Genetics and Collagen Connection
The tissue is densely packed with type I collagen fibrils arranged in a highly organized lattice, interspersed with proteoglycans and elastic fibers. 3 millimeters just behind the rectus muscle insertions.
Conversely, a blue-tinged sclera can be a hallmark of osteogenesis imperfecta, a genetic disorder affecting collagen production. The Cornea: A Functional Comparison To understand the sclera fully, it is essential to contrast it with the cornea, its anterior counterpart.
Understanding the Sclera Genetics and Collagen Connection
The most common alteration is scleral icterus, a yellowing of the white of the eye that signals hyperbilirubinemia, typically associated with liver conditions such as hepatitis or cirrhosis. Clinical Significance and Common Pathologies Changes in the sclera are often the first visible indicators of systemic disease.
