Aqueous humor - Definition

Definition


The aqueous humor is a clear liquid contained in the eye. It is essentially composed of water, is secreted by the ciliary body and then moved to the anterior chamber of the eye in front of the iris, then in a few hours it will be discharged from an orifice called the trabecular meshwork, at the angle of the anterior chamber. The pressure within the anterior chamber is between 10 and 20 mercury millimeters (a unit of pressure used in medicine). If too much of the aqueous humor accumulates due to an imbalance between the input and output of the liquid, the pressure in the eye increases: this is called glaucoma when it exceeds 20 mm Hg.
