Which part of the vitreous exclusively contains hyalocytes?

The correct answer is that the cortical vitreous contains hyalocytes. Hyalocytes are specialized cells found within the vitreous body, primarily located in the cortical region, which is the outer layer of the vitreous. These cells play a crucial role in the maintenance and turnover of the vitreous gel, including the synthesis of hyaluronic acid and the production of other extracellular matrix components that are essential for the structure and function of the vitreous body.

The medullary vitreous, on the other hand, is the central part of the vitreous and is generally less cellular than the cortical vitreous. Instead, it is composed mainly of a gel-like substance. While it does contain some components, its primary function is structural rather than cellular, which is why it has a lower density of hyalocytes compared to the cortical region. The vitreous base, located at the anterior edge of the vitreous where it attaches to the retina, has a different composition and function, focusing more on anchoring the vitreous to the surrounding retinal structures rather than housing hyalocytes specifically.

Understanding the distribution of hyalocytes is essential for recognizing their roles in the overall health of the vitreous and how they may contribute to pathological conditions when their function is impaired
