What does the stroma of the cornea provide?

• A. Structural support
• B. Protection against infections
• C. Light refraction
• D. Barrier against UV radiation

Answer: (A)

The stroma of the cornea is the thickest layer located between the outer epithelial layer and the inner endothelial layer. It is primarily composed of collagen fibers arranged in a precise, regular pattern, which contributes significantly to the cornea's overall structural support. This well-organized collagen structure maintains the shape of the cornea and provides mechanical strength, allowing the cornea to withstand intraocular pressure and physical impact. Additionally, while the stroma plays a critical role in contributing to the transparency and refractive properties of the cornea, its primary function is to provide this structural support. The precise arrangement of the collagen fibers also facilitates the necessary transparency for effective light transmission, which is important for vision. However, the primary descriptor of the stroma's role in this context is its function as a structural support system for the cornea.
