The Posterior Chamber of the Eyeball is a narrow space located behind the peripheral part of the iris and in front of the lens. It is filled with a clear, watery fluid known as the aqueous humour.

Structure[edit | edit source]

The posterior chamber is a small space directly posterior to the iris but anterior to the lens. It is in communication with the anterior chamber through the pupil. The posterior chamber and the anterior chamber together constitute the anterior segment of the eyeball.

Function[edit | edit source]

The primary function of the posterior chamber is to facilitate the circulation of the aqueous humour. The aqueous humour is produced by the ciliary body, flows through the posterior chamber, pupil, and into the anterior chamber. It provides nourishment to the lens and the cornea, which do not have their own blood supply.

Clinical significance[edit | edit source]

Abnormalities in the posterior chamber can lead to several eye conditions. For example, blockage of the flow of aqueous humour can lead to increased pressure in the eye, a condition known as Glaucoma.
