Albinism is caused by a genetic mutation that is usually passed from parents to child. The mutation disrupts the production of melanin, the pigment that protects the skin from UV rays. Melanin is also important for the proper development of the eye. Without melanin, the retina and the optic nerve may not develop properly. The retina is the light-sensitive tissue lining the back of the eye, and the optic nerve fibers, help relay images to the brain.
Albinism can cause a wide range of eye problems. Not all people with albinism have a noticeable lack of color in their skin or hair. So eye problems may be the first sign of albinism.
Some of the symptoms include:
People with albinism can have vision that ranges from normal to severe vision impairment. Near vision is often better than distance vision. Generally, those who have the least amount of pigment have the poorest vision.
