Which part of the eye helps control intraocular pressure?

The aqueous humor is a clear fluid produced in the eye that plays a crucial role in maintaining intraocular pressure, which is essential for the overall health and function of the eye. It is located in the anterior chamber between the cornea and the lens. The production of aqueous humor and its drainage through the trabecular meshwork help regulate the pressure within the eye. Proper intraocular pressure is vital because it supports the shape of the eye and ensures that the various components can function correctly.

While the cornea contributes to the overall structure of the eye and has some influence on pressure dynamics, it does not actively regulate intraocular pressure like the aqueous humor. The lens is primarily responsible for focusing light onto the retina and does not play a role in pressure management. Similarly, the vitreous humor, which is the gel-like substance filling the larger posterior chamber of the eye, does not directly influence the intraocular pressure as it is not involved in fluid production or drainage. Therefore, the aqueous humor is the key component in controlling intraocular pressure.
