Albinism
What
is Albinism?
Albinism is an inherited condition in which
eyes, hair and/or skin have less than normal amounts of pigment. Some children and adults with albinism can have a
total lack of pigment with white skin and hair and pink-colored eyes. Other have only mildly decreased amounts of
pigmentation. One form, ocular albinism,
affects only the eyes leaving the skin and hair pigmentation nearly normal. In severe cases of albinism the eyes central
vision area, the macula does not develop properly resulting in poor vision.
What
Causes Albinism?
Albinism results from the inability of the
normal pigment cells in the eyes, hair or skin to produce normal amounts of pigment. This passes on genetically from parents to
children.
What
are the symptoms of Albinism?
The symptoms of albinism begin early in
childhood and may include decreased vision, sensitivity to bright lights, and
unintentional jiggling movement of the eyes (nystagmus) and misalignment of the eyes
(strabismus0> Vision can range from
normal, for those minimally affected, to legal blindness or worse for those with more
sever forms of albinism. Near vision is often
better than distance vision. Generally those who have the least amount of pigment have the
poorest vision.
How
is Albinism Diagnosed?
Albinism is often suspected from a persons
general appearance or through a family history of the disorder. A complete medical eye exam by an ophthalmologist,
a general physical examination, and a genetic evaluation can help diagnose and define the
type of albinism.
Special tests of the hair shafts, skin or
blood can be used to make a specific diagnosis. In
two rare forms of albinism affected individuals can have bleeding problems increase
susceptibility to infections, especially during childhood.
Early diagnosis is important for proper treatment of these complications.
How is albinism treated?
Albinism is a lifelong condition. Although there is no way to treat poor or absent
pigment production or correct early poor development of central vision, proper eye
evaluations and management can be useful.
Eye misalignment can be treated with
optical or surgical measures and glasses can be prescribed to improve vision and reduce
light sensitivity. Magnifying glasses for
reading and low vision aids for distance vision can also be helpful
Genetic counseling of affected individuals
and their families is recommended. Counselors
will provide the patient and family member with a detailed explanation of the disorder
including the chances of further children being affected.
Some individuals with albinism may be
entitles to help from visual assistance programs. Your
ophthalmologist can make this determination and refer you to the appropriate agency.
Since albinos have to deal with both social
and visual adjustments in daily life, it is often helpful to talk with others who have
similar problems. The National Organization
for Albinism and Hypopigmentation (NOAH) is a nonprofit organization formed for the
benefit of families and individuals with these conditions.
