A brief history of albinism

Albinism causes shortages and loss of color in the skin. Melanin is the body responsible for the shadows on the skin and if there is inadequate or absent, is caused albinism. It can be caused even in the eyes and hair.

Plants and animals can also albinism. Albinism in plants is similar to that of humans. Albino plants are short of chlorophyll and without it, plants do not eat with the help of the sun. This results in her short life. It is unknownif albino people live longer than normal.

Oldest records of albinism are found in Germany and Rome. The first observers of albinism are widely known as Elder Aulus Gellius and Pliny Secundus of. However, Archibald Garrod was the first albino considered as a disease. He led a study on them 1908 and observed that people with albinism were affected very blond hair and skin.

Sometimes albinism causes hair and change to reddark yellow. The eye of a person who can Albino brown, red or blue. You can not stare directly into the sky and sometimes it can be even worse. This is why albinos are usually seen in dark glasses.

Albinos acquire the disease that is transmitted by the genes of the parents. The genes that albinos lack the normal amount of melanin. It is said that the U.S. alone suffer from one person in 17 000 albinism, a more or less. Albinism is notspecifically related to the white people in context. Asian, black, Polynesian and Indian have also been cases of albinism. Albinos usually have normal parents.

Everybody does not necessarily albino white skin. The most common is Oculocutaneous Albinism OCA (). It affects the eyes, skin and hair. OCA comes in different shades, it can manifest symptoms or may only thin pigmentation. A person with mild OCA has milk-colored hair and skin. Sometimes the look of the reddish hair andyellowish and the vision is a little better. Ocular albinism (OA) is on average only to the eyes of a person with skin and hair appear as slightly fairer. These two species were previously considered "complete" and "incomplete" albinism.

In the glasses, it is not possible to correct an albino eyes. The low vision of an albino, depends on the severity of albinism. Albinos are technically blind in most cases. It does not mean that they do not see, but theyWhat to does not have a normal. Albinos are able to read and drive. Your retina and nerves, the eye connects to the brain is not in place. The optic nerve of an albino have irregular patterns. This is the reason that they are not in bright light to stare. You are encouraged to regularly visit their eye doctors.

As noted above, all albinos have no excessive white hairs or skin. But those with OCA show signs of dryness of the skin and rashes. Complete Albinos can not stand the sun for a longTime, in case they have then they would need an umbrella or a sunscreen lotion to protect their skin.
