Transcript of Albinism

Albinism
Albinism (also called achromia, achromasia, or achromatosis) is a disorder, characterized by a partial or total lack of melanin pigment in the eyes, skin and hair (or more rarely the eyes alone).

Hypopigmentation

Oculocutaneous: skin, hair and eyes.
Ocular: eyes.
Symptoms
The albino children are characterized by white or slightly golden hair, pale skin and blue or red violet eyes.

Crossed eyes (strabismus)
Light sensitivity (photophobia)
Rapid eye movements (nystagmus)
Vision problems, or functional blindness

Parts of the integumentary system affected:
Skin & hair
Treatment
There is no known treatment for albinism but what you can do is:
Reduce sunburn risk by avoiding the sun, using sunscreen, and covering up completely with clothing when exposed to the sun.
Sunscreen should have a high sun protection factor (SPF).
Sunglasses (UV protected) may relieve light sensitivity.
How to get it..
A person must inherit two copies of a mutated gene — one from each parent — in order to have albinism. If a person has only one copy, then he or she won't have the disorder. A mutation may result in no melanin production at all or a significant decline in the amount of melanin.
One person in 17,000 in USA has some type of albinism.
Back in medieval times, people would often kill albinos because they were known to take part in witchcraft.
Albinism is not contagious, nor can it be transferred from person to person through blood transfusion, dermal contact, or via vector
People with albinism are at higher risk for developing skin cancer
Various types of albinism are common in Africa.
