Regulation of Aqueous Humor
Aqueous humor is the liquid that is present in the eye. The amount of this liquid is controlled by contraction and relaxation of the longitudinal fibers of the ciliary muscle. These fibers insert into the trabecular mesh-work, which is present in the anterior eye chamber. This causes an increase and decrease in the meshwork pore size, facilitating and impeding aqueous humor flow into the canal of Schlemm, depending on the requirement of the eye.
