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.

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.

The limbus is widest in superior and inferior cornea. Cornea is convex and aspheric. The anterior curvature is 7.8 mm and posterior curvature is about 6.5 mm. Cornea contributes to about 40-44 D of refractive power and accounts for approximately 70% of total refraction. The refractive index of cornea is 1.376.

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.

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.

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.

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.

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.

Limbal function is a key determinant of corneal epithelial integrity. Lineage tracing studies in mice have highlighted that the centripetal movement of epithelial progenitors from the limbus drives both the steady-state maintenance of the corneal epithelium and its regeneration following injury. It.
