THE LIMBUS Eye anatomy, Anatomy, Optometry
The corneoscleral limbus is a unique and critical ocular structure responsible for barrier protection, corneal regeneration and wound repair. These functions are pivotal in maintaining corneal transparency and ocular surface integrity.

The outer coats of the eye are the cornea and sclera; their juncture is the limbus ( Fig 2.1 ). The interior of the eye is divided into the anterior and posterior segments. The anterior segment includes the cornea, iris, ciliary body and lens as well as the spaces of the anterior and posterior chambers filled with aqueous humor.

Your cornea, which is the membrane that covers your eye like a lens, and the sclera, the white part of your eye, meet at ridges on your eye called the "corneal limbus." This border is.

Thus, on looking directly into the eye from in front one sees the white sclera surrounding the cornea; because the latter is transparent one sees, instead of the cornea, a ring of tissue lying within the eye, the iris. The iris is the structure…

The limbus is the border between the clear part of the eye (cornea) and the white part of the eye (sclera). If you look into the mirror at the colored part of your eye, the limbus is the transparent ring that forms a border around it.

Corneal involvement is the result of the spread of abnormal epithelium from the adjacent limbus. The abnormal squamous cells often have a translucent, grayish, frosted appearance. In addition, the corneal lesions often take on a characteristic fimbriated or pseudopodia configuration. [2]

The sclera-corneal junction is called the limbus. Here, the deep surface of the suprachoroid lamina is covered by the scleral endothelium, a simple squamous epithelium. The limbus is the location of corneal stem cells. The sclera is nearly avascular, although it does have some visible blood vessels that pierce the surface to reach the retina below.

The limbus of the eye marks the transition between the cornea and sclera. It is a ring-shaped area that starts off transparent by the cornea and becomes opaque near the sclera. The limbus is typically around 1-2mm wide and helps keep the cornea healthy and clear. is the clear covering at the center of the eye.

A limbal ring is a dark ring around the iris of the eye, where the sclera meets the cornea. [1] It is a dark-colored manifestation of the corneal limbus resulting from optical properties of the region. [2] The appearance and visibility of the limbal ring can be negatively affected by a variety of medical conditions concerning the peripheral.

1.1.4 Corneal stem cells. The limbus of the cornea is located at the junction of the cornea, conjunctiva, and sclera. It differs from conjunctiva as it does not have goblet cells and is about 1 mm wide; the epithelial cell layer contains over 10 layers and is irregularly arranged. Moreover, the cells are rather small and cylindrical and possess.
