Anterior chamber angle labeled

Aqueous fluid is formed by the non pigmented epithelium in the pars plana and ciliary processes and traverses the posterior chamber around the lens and through the opening in the iris called the pupil to reach the anterior chamber. Here aqueous flows through the trabecular meshwork to the canal of Schlemm and finally exists the eye through aqueous veins. Note the iris root is quite thin and clinically prone to rupture with trauma. The number of cells lining the trabecular meshwork has been shown to decrease with age and interestingly in primary open angle glaucoma and pigmentary glaucoma. The cause for the loss of the trabecular lining cells has not been thoroughly investigated.
