Corneal Diseases Categories.
Canadian Medical Guide Definition 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.
Canadian Medical Guide Definition Corneal Edema - An excessive amount of fluid in the cornea due to damage of the epithelium or endothelium causing decreased visual acuity.
Canadian Medical Guide Definition Corneal Neovascularization - New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
Canadian Medical Guide Definition Corneal Opacity - Disorder occurring in the central or peripheral area of the cornea. The usual degree of transparency becomes relatively opaque.
Canadian Medical Guide Definition Keratitis - Inflammation of the cornea.
Canadian Medical Guide Definition Keratoconus - A noninflammatory, usually bilateral protrusion of the cornea, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. The cause is unknown but hereditary factors may play a role. The -conus refers to the cone shape of the corneal protrusion.
