The posterior chamber is a narrow space behind the peripheral part of the iris, and in front of the suspensory ligament of the lens and the ciliary processes.

Posterior chamber is an important structure involved in production and circulation of aqueous humor.

The block in flow of aqueous from the posterior to the anterior chamber will lead to a condition known as Iris bombe.

In this condition, pressure in the posterior chamber rises, resulting in anterior bowing of the peripheral iris and obstruction of the trabecular meshwork.

[5] Surgical management of Glaucoma due to Iris bombe include making a small hole in the iris which allows passage of aqueous from posterior chamber to anterior chamber either by YAG or Argon laser iridotomy [6] or by manual iridectomy.
