Angle of the Eye-Corneoscleral Trabeculae

The anterior chamber of the eye is limited in the front by the cornea and the peripheral sclera, in the back by the anterior iris and the pupillary part of the lens. The border between anterior and posterior chamber of the eye is the angle of the eye or Schwalbe’s line ( angulus iridocornealis). At that line, the corneal epithelium continues in the epithelium of the conjunctiva and the lamellae of the corneal stroma inter weave with the connective tissue of the sclera. From the corneal epithelium and Descemet’s membrane arise the corneoscleral trabeculae, which are a loosely arrange d sponge-like connective tissue. The ocular fluid flows through the meshwork of this sponge-like tissue to the canal of Schlemm . Endothelial cells cover the trabecular surfaces. The intertrabecular space is the space of Fontana. It is the connection between Schwalb e’s line and the canal of Schlemm. This figure conveys an impression of the trabecular structure. The structure cannot be obtained in this form using light microscopy.
