Corneal dystrophies may not apparent movement symptoms (asymptomatic) in some individuals; in others they may cause of signification vision impairment. The age of onset and special symptoms vary among the miscellaneous forms of corneal dystrophy. The disorders have some similar characteristics; most forms of cornea l dystrophy affect both eyes (bilateral), progress slowly, do not affect other areas of the body, and tend to run in families. Most forms are inherited as autosomal plethoric traits; a few are inherited as autosomal recessive traits. An international classification of the corneal dystrophies has been developed that takes into story the chromosomal loci of the various corneal dystrophies as well as the responsible genes and their mutations. Traditionally, these disorders have classified based upon their clinical findings and the slender layer of the cornea affected. Advances in molecular genetics (e.g., identification of precise disease genes) have led to a greater tenability of these disorders. Symptoms The symptoms of corneal dystrophies result from the accumulation of abnormal material at heart the cornea, the clear outer layer of the eye. The cornea serves two functions; it protects the lay of the eye from dust, germs and other harmful or irritating material, and it a cts as the eyes outermost lens, The cornea! must remain clear...If you indigence to gear up a full essay, order it on our website: OrderCustomPaper.com
