The irregularity of the cornea demonstrated here is seen both with recurrent corneal abrasion or a new corneal abrasion, with the history of the patient being the critical difference. Using fluorescent dye helps show the extent of damage from this recurrent corneal abrasion. The irregularity of the layer of cells that covers the surface of the cornea (corneal epithelium), seen here, is a frequent finding in recurrent erosion. This is another example of the irregularity of the layer of cells that covers the surface of the cornea (corneal epithelium) often seen in recurrent erosion.

Overview
Recurrent corneal erosion is the recurrent breakdown of the outermost layer (epithelium) of the cornea. In recurrent corneal erosions, the outermost layer of the cornea fails to glue in tightly to its underlying membrane (basement membrane), making it possible for the epithelium to break off too easily with little effort. There are 3 major causes of recurrent corneal erosion, which are:

  • Previous corneal injury (corneal abrasion).
  • Corneal dystrophy (map dot fingerprint dystrophy) – (abnormal structure changes of the cornea).
  • Underlying corneal disease.
 Please see the section on corneal abrasion.
