H16.431-443 Localized Vascularization of Cornea

Corneal neovascularization is the growth of new blood vessels into the cornea.

H16.251-253 Phlyctenular Keratoconjunctivitis

Phlyctenular keratoconjunctivitis is an inflammation of the cornea and conjunctiva caused by microbial antigens.

H16.231-233 Neurotrophic Keratoconjunctivitis

Neurotrophic keratoconjunctivitis is a degenerative disease of the corneal epithelium resulting from impaired corneal innervation.

H16.221-223 Keratoconjunctivitis Sicca

A disease of the surface of the eye that arises due to either decreased tear film production or increased tear film evaporation.

H16.211-213 Exposure Keratoconjunctivitis

Exposue keratoconjunctivitis occurs when the surface of the conjunctiva or the cornea become dehydrated and damaged secondary to poor tear film wetting.

H16.121-123 Filamentary Keratitis

Filamentary keratitis occurs when strands of mucous and desquamated epithelial cells form corneal filaments that adhere to the corneal epithelium.

H16.041-043 Marginal Corneal Ulcer

Marginal keratitis is an inflammatory reaction in the cornea characterized by subepithelial marginal infiltrates, ocular redness, increased lacrimation, photophobia and ocular discomfort.

H16.011-013 Central Corneal Ulcer

Corneal ulcers are focal white opacities/infiltrates in the corneal stroma with an overlaying epithelial defect.
