Anatomical terminology |
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.

- Corneal damage observed in a viral infection such as herpetic stromal keratitis is mainly caused by proinflammatory molecules released by resident cells in the response to viral antigens. There are pattern recognition receptors like MDA5, RIG-1, and TLR3, that recognize viral dsRNA and after activat
