What is the function of the aqueous humor in the eye?

The function of the aqueous humor in the eye primarily involves maintaining intraocular pressure and providing essential nutrients to the avascular structures, such as the cornea and lens. This clear fluid is produced by the ciliary body and fills the anterior chamber of the eye, contributing to the eye's shape and structural integrity. The pressure it maintains is crucial for proper eye function, as too high or too low pressure can lead to conditions such as glaucoma or other visual impairments.

In addition to pressure regulation, the aqueous humor plays a significant role in delivering nutrients required for cellular metabolism and maintaining the health of the eye, particularly for tissues that do not have their own blood supply. This dual function is vital for overall ocular health, impacting vision and the eye's ability to function properly.

Other options refer to functions that are associated with different components of the eye or visual processes rather than the role of the aqueous humor itself.
