A review of selected inherited corneal dystrophies associated with systemic diseases. 1971


The normal transparency of the cornea permits detailed in vivo study of several human pathologic conditions. Many systemic diseases are associated with corneal dystrophies which are manifested by haziness, opacification, crystalline deposition, or discoloration. Although these abnormal states can sometimes be seen grossly, biomicroscopy with slit lamp illumination is necessary for an exact morphologic description. Only precise delineation can lead to an accurate diagnosis of the corneal disorder and thus provide clues for an associatkd systemic disease.

UI MeSH Term Description Entries
D007057 Ichthyosis Any of several generalized skin disorders characterized by dryness, roughness, and scaliness, due to hypertrophy of the stratum corneum epidermis. Most are genetic, but some are acquired, developing in association with other systemic disease or genetic syndrome. Xeroderma,Ichthyoses,Xerodermas
D007640 Keratoconus A noninflammatory, usually bilateral protrusion and thinning of the CORNEA, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. Two closely related noninflammatory corneal ectasias are pellucid marginal degeneration and keratoglobus. Keratoglobus,Pellucid Marginal Corneal Degeneration,Pellucid Marginal Degeneration,Degeneration, Pellucid Marginal,Marginal Degeneration, Pellucid,Pellucid Marginal Degenerations
D008548 Melanosis Disorders of increased melanin pigmentation that develop without preceding inflammatory disease. Chloasma,Freckles,Melanism,Melasma,Chloasmas,Freckle,Melanoses,Melasmas
D009083 Mucopolysaccharidoses Group of lysosomal storage diseases each caused by an inherited deficiency of an enzyme involved in the degradation of glycosaminoglycans (mucopolysaccharides). The diseases are progressive and often display a wide spectrum of clinical severity within one enzyme deficiency. Mucopolysaccharidosis
D009506 Nevus A circumscribed stable malformation of the skin and occasionally of the oral mucosa, which is not due to external causes and therefore presumed to be of hereditary origin. Mole, Skin,Moles, Skin,Skin Mole,Nevi,Skin Moles
D003315 Cornea The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed) Corneas
D003317 Corneal Dystrophies, Hereditary Bilateral hereditary disorders of the cornea, usually autosomal dominant, which may be present at birth but more frequently develop during adolescence and progress slowly throughout life. Central macular dystrophy is transmitted as an autosomal recessive defect.

D003554 Cystinosis A metabolic disease characterized by the defective transport of CYSTINE across the lysosomal membrane due to mutation of a membrane protein cystinosin. This results in cystine accumulation and crystallization in the cells causing widespread tissue damage. In the KIDNEY, nephropathic cystinosis is a common cause of RENAL FANCONI SYNDROME.

D003937 Diagnosis, Differential Determination of which one of two or more diseases or conditions a patient is suffering from by systematically comparing and contrasting results of diagnostic measures. Diagnoses, Differential,Differential Diagnoses,Differential Diagnosis
D004402 Dysautonomia, Familial An autosomal disorder of the peripheral and autonomic nervous systems limited to individuals of Ashkenazic Jewish descent. Clinical manifestations are present at birth and include diminished lacrimation, defective thermoregulation, orthostatic hypotension (HYPOTENSION, ORTHOSTATIC), fixed pupils, excessive SWEATING, loss of pain and temperature sensation, and absent reflexes. Pathologic features include reduced numbers of small diameter peripheral nerve fibers and autonomic ganglion neurons.
