The corneal limbus (Latin: corneal border) is the border between the cornea and the sclera (the white of the eye). It contains limbal stem cells in its palisades of Vogt. It may be affected by cancer or aniridia (a developmental problem), among other issues.

2021年4月15日 · 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.

2023年11月6日 · 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.

1989年3月1日 · The limbus forms the border between the transparent cornea and opaque sclera, contains the pathways of aqueous humour outflow, and is the site of surgical incisions for cataract and glaucoma.

The limbus is populary described by the surgeons as a blue-grey transition zone seen around the cornea after reflection of the conjunctiva. This blue-grey ring spans a width of about 1.2 mm between the white sclera posteriorly and the transparent cornea anteriorly.

The corneal edge, or limbus, located at the corneoscleral junction, is a band that encircles the peripheral cornea (Fig. 1). It is a transitional zone between the cornea and the conjunctiva and the cornea and sclera.

Limbus is formed by the junction of the corneal and conjunctival epithelia, where the epithelium gradually becomes thicker toward the sclera. It is a 1–2-mm-wide anatomical ring-shaped transition zone between the opaque sclera and the clear cornea.

2022年9月15日 · Unlike other ocular structures, the cornea is free of blood vessels, which allows for its transparency. The vasculature of the limbus, as well as the tear film, is what nourishes the cornea. The limbus is the zone that prevents the opaque conjunctival epithelium from invading the otherwise clear cornea. 1-5. Damage and Disease

The corneal limbus (Corneoscleral junction) is the junction of the cornea and the sclera (the white of the eye). The limbus contains radially-oriented fibrovascular ridges known as the palisades of Vogt that may harbour a stem cell population.The palisades of Vogt are more common in the superior and inferior quadrants around the eye.

2022年11月9日 · The limbus contains stem cells that are responsible for renewing the outer layer (epithelium) of the cornea, especially after the eye is wounded, such as from a fingernail scrape. Damage to the limbus may be caused by contact lenses, chemical burns, or …
