[2] The corneal limbus contains radially-oriented fibrovascular ridges known as the palisades of Vogt that contain limbal stem cells.

[1][3] The palisades of Vogt are more common in the superior and inferior quadrants around the eye.

Aniridia, a developmental anomaly of the iris, disrupts the normal barrier of the cornea to the conjunctival epithelial cells at the limbus.

The corneal limbus may be cut to allow for aqueous humour to drain from the anterior chamber of the eye into the subconjunctival space.

[5] Trabeculectomy, a surgery used to treat glaucoma, is best performed with an incision through the superior part of the corneal limbus.
