Ocular Albinism

Albinism
Albinism
Albinism Albinism is a term used to describe people and animals that have little or no pigment in their eyes, skin, or hair. People with this condition have inherited genes that do not produce normal amounts of a pigment called melanin. It is equally common to all races and consists of two major classes. The first, Oculocutaneous albinism includes eyes, skin, and hair. Ocular, the second, involves mainly the eye. The oculocutaneous variety can be divided into 10 different types, the most common

Albinism INTRODUCTION For my research project I have chosen the genetic disease albinism. There are a few reasons why I chose albinism as my topic. First and foremost, in kindergarten I had a friend who was an albino, and although I have not seen him in over 10 years I am still curious as to what the causes of albinism are. Back then, my mother explained it to me by saying, ?that's just the way his skin is? which is a fine way to explain it to a five year old, but now I find myself wanting to kn

Visual Impairment Vision Impairments People catergorized as visually impaired range from individuals with mild visual losses to those with low vision to those who are totally blind (Winzer,370). Vision impairments does not necessarily mean a total loss of sight. Some visually impaired person can detect light, others can see shapes and forms, and others can see nothing at all. Generally, many different problems that interfere the retina to form image or the transmission of retinal images to the b

Albinism The word albinism refers to a group of inherited conditions. People with albinism have little or no pigment in their eyes, skin, or hair. Recently a test has been developed to identify carriers of the gene for ty-neg albinism and for other types in which the tyrosianase enzyme does not function. The test uses a sample of blood to identify the gene for the tryrosinase enzymes by its code in DNA. The above test does not apply to to one type of albinism, called X-linked ocular albinism. F

Vision La visi?n es el sentido de la relaci?n social por excelencia, del aprendizaje y de la comunicaci?n. Su ausencia o disminuci?n suponen una seria desmejora para el individuo que las presenta con importantes consecuencias para el aprendizaje. En el contexto de la asistencia tecnol?gica para describir aquellas personas con impedimentos visuales se utilizan los t?rminos: ?Visi?n parcial? -- indica que alg?n tipo de problema visual ha resultado en la necesidad de servicios de educaci?n especial
