H18.423 Band Keratopathy
Band keratopathy is a corneal disease derived from the appearance of calcium on the central cornea.
H18.831-833 Recurrent Erosion of Cornea
A corneal erosion is characterized by a spontaneous detachment of the basal cells of the corneal epithelium from the underlying basement membrane.
H18.821-823 Corneal Disorder due to Contact Lens
Contact lens wear can cause a change in corneal physiology, which may lead to lead to epithelial, stromal, and endothelial compromise.
H18.731-733 Descemetocele
Descemetocele involves the anterior bulging or rupture of an intact Descemet's membrane through a defect of the overlying corneal stroma and epithelium.
H18.711-713 Pellucid Marginal Degeneration
Pellucid marginal degeneration is a condition characterized by peripheral corneal thinning and corneal ectasia.
H18.621-623 Keratoconus Acute Hydrops
Corneal hydrops occurs after a rupture in Descemet's membrane and is characterized by severe corneal edema.
H18.611-613 Keratoconus
Keratoconus is a disease of the cornea. It is characterized by progressive thinning of the corneal stroma and a progressive steepening in the shape of the cornea.
H18.59 Posterior Polymorphous Dystrophy
A form of corneal dystrophy characterized by a metaplasia of endothelial cells.
H18.59 Anterior Corneal Dystrophies
Epithelial basement membrane dystrophy (EBMD) is a degenerative condition of the anterior layer of the cornea.
H18.51 Endothelial Corneal Dystrophy
Endothelial corneal dystrophy is characterized by corneal guttata and other morphologic abnormalities of the endothelium.
