The term "aqueous humour of the eye" refers to a transparent, gel-like fluid that fills the anterior chamber of the eye, located between the cornea and the lens. It plays a crucial role in maintaining the shape and health of the eye. The aqueous humour is composed mainly of water, proteins, and nutrients that are essential for nourishing the surrounding tissues of the eye.
One of the primary functions of the aqueous humour is to provide nourishment and oxygen to the cornea and lens, as they do not possess their own blood supply. It also helps remove waste products, such as carbon dioxide, from these structures. Additionally, the aqueous humour aids in regulating the intraocular pressure within the eye, which is crucial for maintaining optimal vision.
The production and drainage of the aqueous humour are vital for the proper functioning of the eye. It is produced by the ciliary body, a structure located behind the iris, and then flows through the pupil into the anterior chamber. The fluid is continuously circulated and drained through tiny drainage channels, called the trabecular meshwork, located at the periphery of the iris. Any disruption in the production or drainage of the aqueous humour can lead to imbalances in intraocular pressure, potentially causing vision problems like glaucoma.
In summary, the aqueous humour of the eye is a transparent fluid that provides nourishment, regulates intraocular pressure, and maintains the overall health and shape of the eye.
