Aqueous humor
Aqueous Humor
Aqueous Humor (/ˈeɪkwiəs ˈhjuːmər/), from the Latin aqua meaning water and humor meaning fluid, is a clear, watery fluid located in the anterior and posterior chambers of the eye. It is responsible for maintaining the intraocular pressure and providing nutrients to the avascular ocular tissues.
Function
The primary function of the Aqueous Humor is to maintain the intraocular pressure of the eye. It also provides nutrients to the avascular ocular tissues such as the cornea and the lens.
Production and Drainage
The Aqueous Humor is produced by the ciliary body, a part of the eye located behind the iris. It is drained through the trabecular meshwork into the Schlemm's canal, and then into the bloodstream.
Disorders
Disorders related to the Aqueous Humor include glaucoma, a condition characterized by increased intraocular pressure due to improper drainage of the Aqueous Humor. Another disorder is uveitis, an inflammation of the uvea, which can affect the production of Aqueous Humor.
