Corneal
|
|
CornealPertaining to the cornea, the clear front window of the eye that transmits and focuses light into the eye.
RELATED TERMS--------------------------------------
Cornea
The front part of the eye that acts as a window for the entrance of light rays. It is attached to the other outer coat of the eye, the sclera; the white part of the eye. The cornea provides a significant amount of focusing power for the eye (the rest is provided by the lens). Because it has many nerve fibers, an injury or foreign body causes significant pain and discomfort.
Eye
The organ of sight. The eye has a number of components. These components include but are not limited to the cornea, iris, pupil, lens, retina, macula, optic nerve, choroid and vitreous.
SIMILAR TERMS--------------------------------------
Corn
A hardened area of skin on the foot caused by persistent friction or pressure.

Because it has many nerve fibers, an injury or foreign body causes significant pain and discomfort.
Corneal abrasion
A scratch or scrape on the cornea, the clear front window of the eye that transmits and focuses light into the eye.
Corneal dystrophy
A condition in which one or more parts of the cornea lose their normal clarity due to a buildup of cloudy material. There are over 20 corneal dystrophies that affect all parts of the cornea.
Corneal dystrophy, Cogan
A disorder in which the cornea (the normally clear front window of the eye) shows grayish fingerprint lines, geographic map-like lines, and dots (or microcysts) on examination with a slit-lamp that focuses a high intensity light beam as a slit while the examiner looks at the front of the eye through a magnifying scope. The disorder is usually silent and without symptoms. However, about one patient in ten has recurrent erosion of the cornea that usually begins after the age 30.
Corneal dystrophy, epithelial basement
A disorder in which the cornea (the normally clear front window of the eye) shows grayish fingerprint lines, geographic map-like lines, and dots (or microcysts) on examination with a slit-lamp that focuses a high intensity light beam as a slit while the examiner looks at the front of the eye through a magnifying scope. The disorder is usually silent and without symptoms. However, about one patient in ten has recurrent erosion of the cornea that usually begins after the age 30.
Corneal dystrophy, Fuchs endothelial
A common adult-onset form of corneal dystrophy with autosomal dominant inheritance. The disorder is caused by mutation in the COL8A2 gene.
Corneal dystrophy, map-dot-fingerprint type
A disorder in which the cornea (the normally clear front window of the eye) shows geographic map-like lines, dots (or microcysts), and grayish fingerprint lines on examination with a slit-lamp, a device that focuses a high intensity light beam as a slit while the examiner looks at the front of the eye through a magnifying scope.
Corneal dystrophy, microcystic
A disorder in which the cornea (the normally clear front window of the eye) shows dots (or microcysts), geographic map-like lines, and grayish fingerprint lines on examination with a slit-lamp, a device that focuses a high intensity light beam as a slit while the examiner looks at the front of the eye through a magnifying scope. The disorder is usually silent and without symptoms. However, about one patient in ten has recurrent erosion of the cornea that usually begins after the age 30.
Corneal ring, intrastromal
A plastic ring designed to be implanted in the cornea, the transparent structure in the front of the eye.
Corns
Small calloused areas of skin caused by local pressure irritating tissue over a bony prominence. Corns most commonly occur over a toe where they form what is referred to as a hard corn. Between the toes, pressure can form a soft corn of macerated skin which often yellows.
PREVIOUS AND NEXT TERMS--------------------------------------
Copy number polymorphism
Abbreviated CNP. A normal variation in DNA due to variation in the number of copies of a sequence within the DNA. Large-scale copy number polymorphisms are common and widely distributed in the human genome.
Cor
The Latin word for the heart.
Cor biloculare
A two-chambered heart. Cor biloculare is due to failure of development of the walls that normally separate the two atria (interatrial septum) and the two ventricles (interventricular septum).
Cord
1. In anatomy, a long ropelike structure. 2. Short for the spinal cord or the umbilical cord.
Cordectomy
1. Surgical removal of a vocal cord. 2. Surgical removal of part of the spinal cord.
