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. Anatomically, the limbus contains important features related to eye functions including fibrovascular ridges radially oriented known as palisades of Vogt that host corneal stem cells for epithelial turnover. Scanning electron microscopy (SEM) is a technique for obtaining high-resolution images of biological and nonbiological specimens.
Our aim was to show the ultrastructure of the corneal limbus using SEM [Figure 1].
