Sclera

The sclera is the dense, fibrous tissue that forms the outer shell of the eyeball, providing structural integrity and protection. Its primary function is to maintain the shape of the eye and support the delicate internal structures, such as the retina and the choroid. The sclera is predominantly composed of collagen fibers arranged in a dense matrix, giving it its tough and opaque appearance.

From a clinical standpoint, the sclera's color and texture can offer diagnostic insights into various eye conditions. Changes in scleral color or thickening may indicate underlying health issues, such as inflammation (scleritis) or systemic diseases affecting collagen metabolism. Ophthalmologists routinely examine the sclera during eye exams to detect abnormalities early and monitor eye health. Understanding the sclera's anatomy and its clinical significance is crucial for diagnosing and managing a wide range of ocular disorders effectively.
