Posterior chamber of eyeball
(Redirected from Posterior chamber of eye)
Part of the eye between the iris and the lens
The posterior chamber of the eyeball is a narrow space located in the eye between the iris and the lens. It is one of the three chambers of the eye, the other two being the anterior chamber and the vitreous chamber.
Anatomy[edit | edit source]
The posterior chamber is filled with a clear, watery fluid called aqueous humor. This fluid is produced by the ciliary body, which is located just behind the iris. The aqueous humor flows from the posterior chamber through the pupil into the anterior chamber, and then drains out of the eye through the trabecular meshwork and Schlemm's canal.
Function[edit | edit source]
The primary function of the posterior chamber is to produce and regulate the flow of aqueous humor, which is essential for maintaining intraocular pressure and providing nutrients to the avascular structures of the eye, such as the lens and cornea. Proper functioning of the posterior chamber is crucial for maintaining the health and optical properties of the eye.
Clinical Significance[edit | edit source]
Disorders of the posterior chamber can lead to various eye conditions. For example, an imbalance in the production or drainage of aqueous humor can result in increased intraocular pressure, leading to glaucoma. Inflammation of the structures within the posterior chamber, such as uveitis, can also affect vision and eye health.
