Glossary for Corneal Dystrophies

Age-related macular degeneration: Deterioration of the central field of vision.
Cataracts: Cloudy areas on the eye's cornea interfering with vision.
Chandler's syndrome: A very rare eye disorder characterized by progressive corneal dystrophy and glaucoma which result in loss of vision.
Cornea disorders: Disorders affecting the cornea of the eye
Corneal dystrophy Avellino type: A rare inherited eye disorder involving degeneration of the cornea. The degeneration is caused by granular deposits in the cornea as well as deposits of amyloid in a lattice pattern on the cornea. The condition occurs as a result of a genetic defect on chromosome 5q31.
Corneal dystrophy of Bowman layer, type 1: A rare inherited eye disorder involving degeneration of the cornea which gives the cornea a characteristic geographic or map-like appearance. The Bowman membrane of the cornea is the main area affected. The condition occurs as a result of a genetic defect on chromosome 5q31.
Corneal dystrophy of Bowman layer, type 2: A rare inherited eye disorder involving degeneration of the cornea which gives the cornea a characteristic honeycomb appearance. The Bowman membrane of the cornea is the main area affected. The condition occurs as a result of a genetic defect on chromosome 5q31 or 10q24.
Corneal dystrophy, Fuchs' endothelial, 1: A rare inherited eye disorder involving degeneration of the inner (epithelial) layer of the cornea. In type 1, onset occurs early in life (from early childhood) and usually takes about 20 years to affect vision.
Corneal dystrophy, Fuchs' endothelial, 2: A rare inherited eye disorder involving degeneration of the epithelial layer of the cornea. In type 2, onset occurs later in life (usually 30-40 years of age) and usually takes about 20 years to affect vision.
Corneal dystrophy, gelatinous drop-like: A rare inherited eye disorder involving degeneration of the cornea which gives the cornea a characteristic lumpy gelatinous appearance (similar to the surface of a mulberry). A substance called amyloid is deposited in the cornea in a lattice pattern. The condition occurs as a result of a genetic defect on chromosome 1p32.
Corneal dystrophy, juvenile epithelial of Meesmann: A rare eye disorder characterized by chilidhood onset of degeneration of the cornea (clear covering of the eye) which impairs vision. Both eyes are affected.
Eye conditions: Any condition that affects the eyes
Eye pain: Pain affecting the eye
Fuchs' Dystrophy: Cataract-like vision problems from corneal deposits.
Glaucoma: Glaucoma is the term for a diverse group of eye diseases, all of which involve progressive damage to the optic nerve. Glaucoma is usually, but not always, accompanied by high intraocular (internal) fluid pressure. Optic nerve damage produces certain characteristic visual field defects in the individual's peripheral (side), as well as central, vision.
Keratoconus: A rare degenerative eye disorder where the corneas of the eye become progressively thinner and cone-shaped which affects vision.
Keratosis palmoplantaris - corneal dystrophy: A rare condition where a deficiency of a liver enzyme (tyrosinase aminotransferase) causes tyrosine levels in the blood to increase and result in eye problems, mental retardation and horny skin lesions which develop on pressure points on the hands and feet.
Lattice dystrophy: Cloudiness of the cornea
Macular dystrophy, corneal type 1: A rare genetic eye disease that affects the cornea. The condition is progressive.
Map-dot-fingerprint dystrophy.: Eye cornea condition
Mousa-Al Din-Al Nassar syndrome: A very rare syndrome characterized mainly by ataxia, spasticity and eye anomalies.
Oculocutaneous tyrosinemia: A rare condition where a deficiency of a liver enzyme (tyrosinase aminotransferase) causes tyrosine levels in the blood to increase and result in eye problems, mental retardation and horny skin lesions.
Open-angle glaucoma: Vision damage from a slow chronic buildup of fluid pressure in the eye.
Poikiloderma of Rothmund-Thomson: A rare disease which causes sufferers to have a senile-like appearance with skin, growth, hair and eye abnormalities.
Senter syndrome: A rare genetic ectodermal disorder characterized by ichthyosiform erythroderma and sensorineural deafness.
Visual impairment: A condition that affects ones vision
