The corneal limbus is the border of the cornea and the sclera (the white of the eye). The limbus is a common site for the occurrence of corneal epithelial neoplasm. The limbus contains radially-oriented fibrovascular ridges known as the palisades of Vogt that may harbour a stem cell population.[1] The palisades of Vogt are more common in the superior and inferior quadrants around the eye.[2] Aniridia, a developmental anomaly of the iris, disrupts the normal barrier of the cornea to the conjunctival epithelial cells at the limbus.
