Which vitreous area contains a higher concentration of collagen?

The correct answer is the cortical vitreous, which is the area of the vitreous humor located near the retina. This region experiences a higher concentration of collagen fibers compared to the medullary vitreous, which is the more central part of the vitreous body.

The higher collagen density in the cortical vitreous contributes to its structural integrity and its ability to maintain adherence to the retinal surface. The arrangement of collagen fibers in this region provides both support and the necessary tensile strength to resist the forces that may lead to detachment of the retina.

In contrast, the medullary vitreous contains a more gel-like consistency with a lower concentration of collagen, allowing for a fluid environment that helps with the movement and flexibility of the vitreous body. The vitreous base, while also significant for its attachment to the retina, does not represent a distinct area with higher collagen compared to the cortical region.

Thus, understanding the composition and arrangement of collagen within these areas is crucial for comprehending their roles in eye anatomy and potential pathologies associated with changes in the vitreous structure.
