Corneal Degenerations

Encyclopedia of Ophthalmology

  • 8 Accesses

Definition

Corneal degenerations are a group of sporadic and age-related corneal conditions that are present in previously normal corneal tissue and occur most often near the limbus.

Basic Characteristics

Degenerative corneal processes are characterized by secondary changes in previously normal corneal tissue. Compared to corneal dystrophies, degenerative processes are not inherited, usually affect more than one corneal layer, and are asymmetric, unilateral, and usually peripheral. Often corneal degeneration is associated to neovascularization and inflammation.

There are many corneal degenerative conditions including Salzmann’s nodular degeneration, calcific band keratopathy, lipid keratopathy, actinic keratopathy, pannus, and bullous keratopathy.
