The function of the aqueous humour is used to increase the amount of light that reaches the retina. On average, the ciliary body produces aqueous humour around 2.5 μl per minute.
Full Answer
Functions of an Aqueous Humor Keeps the intraocular pressure and pumps up the globe of the eye. It is this hydrostatic pressure which keeps the eyeball in a roughly round shape and keeps the walls of the eyeball tight.
While the trabecular meshwork drains the majority of aqueous humour, the uveoscleral route drains about 10% of it. The aqueous humour flows across the iris as well as the anterior side of the ciliary muscle into the suprachoroidal space, which is a space between the sclera and choroid.
Aqueous humor is produced into the posterior chamber by the ciliary body, particularly the non-pigmented epithelium of the ciliary body (pars plicata).
From there, the aqueous humor exits the eye through the trabecular meshwork into Schlemm’s canal (a channel at the limbus, i.e., the signing up with point of the cornea and sclera, which encircles the cornea) It streams through 25-30 collector canals into the episcleral veins.
Without getting too technical, the ciliary body constantly produces aqueous humour (located in the anterior chamber near the lens of the eye). For proper functioning, the production must be balanced by drainage at an equal rate.
Aqueous Humor Location. The anterior and posterior chambers of the eye contain aqueous, thin, watery fluid. The anterior chamber is located between the iris (the coloured part of the eye) and the cornea's inner surface (the front of the eye). The posterior chamber is behind the iris and ahead of the lens. A large portion of the eyeball is made up ...
Even minor changes in the production or outflow of aqueous humour are significant because they have a big impact on your intraocular pressure.
On average, the ciliary body produces aqueous humour around 2.5 μl per minute. The three processes that play a part in this production include the following:
While the trabecular meshwork drains the majority of aqueous humour, the uveoscleral route drains about 10% of it. The aqueous humour flows across the iris as well as the anterior side of the ciliary muscle into the suprachoroidal space, which is a space between the sclera and choroid.
After that, the ciliary body epithelium actively secretes aqueous fluid into the posterior chamber. A Na+/K+ ATPase hydrolyzes ATP for energy in this active process. Water from the ciliary body's stroma follows the Na+/K+ ATPase as it actively transports Na+ ions into the posterior chamber of the eye.
It is important to note that the sympathetic nervous system influences aqueous humour secretion. The activation of beta-2 adrenoceptors as well as alpha-2 adrenoceptors increases and decreases the production of aqueous humour, respectively.
