| corneal neovascularization | New blood vessels originating from the corneal veins and extending from the limbus into the adjacent corneal stroma. These vessels may lie in the superficial and/or deep corneal stroma. Neovascularization is a sequel to numerous inflammatory diseases of the ocular anterior segment, including trachoma, viral interstitial keratitis, microbial keratoconjunctivitis, and the immune response elicited by corneal transplantation.

|---|---|
| corneal oedema | An excessive amount of fluid in the cornea due to damage of the epithelium or endothelium causing decreased visual acuity. (12 Dec 1998) |
| corneal opacity | Clouding that can occur in the cornea secondary to inflammation, infection or irritant exposure (foreign body or chemical). Physicians can visualize the corneal for the presence of opacities using the slit lamp (eye scope). (27 Sep 1997) |
| corneal pannus | Fibrovascular connective tissue that proliferates in the anterior layers of the peripheral cornea in inflammatory corneal disease, particularly trachoma in which the pannus involves the superior cornea. Three forms occur: (05 Mar 2000) |
| corneal reflex | A contraction of the eyelids when the cornea is lightly touched with a camel-hair pencil. Synonym: lid reflex. Reflection of light from the surface of the cornea. (05 Mar 2000) |
| corneal space | One of the stellate space's between the lamellae of the cornea, each of which contains a cell or corneal corpuscle. Synonym: lacuna. (05 Mar 2000) |
| corneal spot | A moderately dense opacity of the cornea. Synonym: corneal spot. (05 Mar 2000) |
| corneal staphyloma | A bulging near the anterior pole of the eyeball. Synonym: corneal staphyloma. (05 Mar 2000) |
| corneal stroma | The lamellated connective tissue constituting the thickest layer of the cornea between the bowman and descemet membranes. (12 Dec 1998) |
| corneal topography | Measurement of the anterior surface of the cornea, its curvature and shape. It is used often to diagnose keratoconus and other corneal diseases, and corneal changes after keratotomy and keratoplasty. A significant application is in the fitting of contact lenses. In performing corneal topography, many different techniques can be employed: keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing, etc. (12 Dec 1998) |
| corneal transplant | A surgical procedure to replace a damaged cornea with a healthy one from a donor's eye. Unlike transplantation of most other organs, the cornea tends to have a problem with transplant rejection. Corneal transplants are indicated in cases of severe corneal injury or corneal infection (corneal ulcer) which has left the cornea scarred. (27 Sep 1997) |
| corneal transplantation | Partial or total replacement of the cornea from one human or animal to another. (12 Dec 1998) |
| corneal trepanation | corneal transplant |
| corneal ulcer | An infectious process of the cornea, resulting in clouding of the cornea, marked eye pain and decreased vision. See: Herpes simplex keratitis. (27 Sep 1997) |
| Salzmann's nodular corneal degeneration | Large and prominent nodules of a solid, opaque material that stands out from the surface of the cornea; occurs occasionally in persons previously affected by phlyctenular keratitis. (05 Mar 2000) |
