THE LIMBUS Eye anatomy, Anatomy, Optometry
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.

The limbus is the transition zone preventing the opaque epithelium from invading the clear cornea. Click image to enlarge. Cells and Components LSCs are most concentrated in areas of the limbus called the palisades of Vogt. To a lesser degree, they are also located in limbal epithelial crypts and the limbal epithelial pit.

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 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 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.

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.
Recent discovery could save peoples' sight
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]

LSCD can be caused by any process that diminishes the number of stem cells or disturbs the stem cell environment. 1 With the exception of some congenital conditions and neoplasia, each of the disorders listed in the table, next page, is associated with significant ocular surface inflammation.

Head and Neck Anatomy Eyeball Sclera
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 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.
