It is caused by several rare genetic disorders that, in addition to causing hypopigmentation (an abnormally low amount of melanin) or depigmentation (complete loss of pigment) of the skin, also affect the eyes with decreased vision, misalignment of the eyes (strabismus Strabismus Strabismus is an intermittent or constant misalignment of an eye so that its line of vision is not pointed at the same object as the other eye. If untreated, strabismus can cause amblyopia ... read more ), and involuntary eye movements (nystagmus).
A type of albinism, called ocular albinism, affects the eyes but usually not the skin and hair. Another type of albinism occurs with bleeding disorders.
Albinism is easily recognized by its typical appearance, including white hair, pale or white skin, and pink or pale blue-gray eyes. People's eyes are very sensitive to light and they often try to avoid bright light.
People who have less typical types of albinism may have some color to their skin, their hair may be somewhat red, and/or their eyes may be blue or brown.
