Corneal degeneration unspecified
2008 ICD-9-CM Diagnosis Code 371.41
Senile corneal changes
  • Degenerative changes of the cornea related to aging that are highly influenced by changes in the corneal endothelium. Changes include corneal topography, increased density, decreased hydration of the corneal stroma, and epithelial basement membrane dystrophy; The stroma appears hazier than in younger eyes and reduces light transmission. Changes may also include age-related stromal degeneration and deposition.

Unspecified corneal disorder
  • pathological process affecting the transparent anterior portion of the fibrous coat of the eye.
  • The transparent part of the eye that covers the iris and the pupil and allows light to enter the inside.
  • The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous epithelium, Bowman's membrane, stroma, Descemet's membrane, and mesenchymal endothelium. It serves as the first refracting medium of the eye. It is structurally continuous with the sclera, is avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the trigeminal nerve via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
