Small variations in the production or outflow of the aqueous humor will have a large influence on your intraocular pressure.
And may affect the quality of image your eye produces. If intraocular pressure is increased, it can lead to glaucoma, one of the leading causes of vision loss. Aqueous Humor and its Role in the Eye. Aqueous humour is made by the ciliary body. Strands from the ciliary body support the lens behind the coloured part of the eye iris. Aqueous humour flows into the front of the eye through the pupil. Aqueous humour drains out of the eye through the trabecular meshwork.
The trabecular meshwork is a spongy mass of tiny canals located in the drainage angle. The drainage angle is located between the iris and the clear covering of the eye cornea , where the iris meets the white outer covering sclera of the eye.
From the ciliary body, aqueous humor flows through the pupil and into the anterior chamber. Aqueous humor then leaves the anterior chamber through a structure called the drainage angle.
Once inside the drainage angle, the aqueous fluid leaves the eye through a spongy tissue called the trabecular meshwork. Imbalances in the amount of aqueous produced and aqueous drained can lead to ocular hypertension , or high eye pressure. This can occur because of an overproduction of aqueous humor or an insufficient drainage of it. As mentioned earlier, aqueous humor leaves the eye through the drainage angle.
The narrower the drainage angle becomes, the more difficult it is for the aqueous humor to drain.
