Oculocutaneous albinism involves the eyes, hair, and skin. Ocular albinism
involves primarily the eye. People with ocular albinism may have slight
lightening of hair and skin colors as well, compared to other family members. At
present researchers have found 10 different types of oculocutaneous albinism,

albinism, including......
