Its primary role is as a rigid shield, protecting the retina, choroid, and delicate intraocular structures from trauma and external pressure. Evolutionary and Developmental Perspectives.
Understanding Sclera Health: The White of the Eye
Anatomy and Composition of the Sclera Comprising approximately 80% of the eye's surface area, the sclera is not a static shell but a dynamic matrix. A slit-lamp examination allows for a detailed view of the surface and superficial vessels, while imaging technologies like anterior segment optical coherence tomography (AS-OCT) provide cross-sectional views of the tissue architecture.
It contains lymphatic channels and immune cells that help monitor and respond to pathogens attempting to breach the ocular surface, making it a frontline defender in the battle against ocular infections. The scleral surface also provides secure insertion points for the six extraocular muscles, enabling the precise and coordinated movements necessary for vision.
Understanding Sclera Health: The White of the Eye
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. The sclera , often recognized as the white of the eye, is a fascinating and complex structure that forms the protective outer layer of the eyeball.
