Which liquid is responsible for maintaining the pressure within the eye?

The aqueous liquid is the clear fluid that fills the space between the lens and the cornea in the front part of the eye. This fluid plays a crucial role in maintaining intraocular pressure, which is essential for the overall health and shape of the eye. Proper pressure helps ensure that the eye maintains its necessary form and supports the structures within it, allowing for optimal vision.

Additionally, the aqueous liquid is involved in providing nutrients to the avascular structures of the eye, such as the lens and cornea, and assists in the removal of metabolic wastes. The production and drainage of this fluid are carefully balanced; any disruption can lead to conditions like glaucoma, which is characterized by increased intraocular pressure. In contrast, the other substances mentioned do not have the same function in maintaining eye pressure.
