Ligament of the Iridocorneal Angle Pectinate: Anatomy and Function

The pectinate ligament of the iridocorneal angle (PNA) is an important structure of the eye that plays a role in maintaining normal intraocular pressure and drainage of intraocular fluid. In this article, we will look at the anatomy and function of the iridocorneal angle pectineal ligament.

Anatomy

The pectineal ligament of the iridocorneal angle is located in the anterior chamber of the eye, which is located between the cornea and the iris. It is a set of ridge-shaped processes that arise from the inner surface of the cornea and extend to the iris.

The pectineal processes of the ligament of the iridocorneal angle of the pectineate have the appearance of jagged projections and form the so-called “comb edge”. This margin plays an important role in draining the intraocular fluid that is produced in the eye and must be constantly removed to maintain normal intraocular pressure.

Function

The pectineal ligament of the iridocorneal angle plays an important role in ensuring the drainage of intraocular fluid, which is produced in the eye and must exit from it through the angle of the anterior chamber. If drainage does not occur properly, increased intraocular pressure may occur, which can lead to various diseases such as glaucoma.

In addition, the iridocorneal angle pectineal ligament plays a role in maintaining the shape of the iris and regulating pupil size. It is also the attachment point for some of the eye muscles that control pupil movement.

conclusions

The iridocorneal angle pectineal ligament is an important structure of the eye that plays a role in maintaining normal intraocular pressure and drainage of aqueous humor. Its anatomy and function are important for understanding the mechanisms that ensure normal functioning of the eye.

The lacrimal ridge is the musculoskeletal system of the eye. It connects the iris with the sclera and is involved in stabilizing the position of the eyeball in the orbit. The cornea is connected to the eyeball by several ligaments. They even do the job in two directions - they protect and fix the eyeball. In Latin the ligaments are called "ligamenta tela pupillae". There are also 2 more ligaments: zonulocutaneous (ligamentum zonulolenticulare mediale et laterale) and ciliary (palpebrae superioris rima). They are located between the iris and the eyeball.
