How Is Albinism Treated? Albinism represents a group of conditions characterized by a defect in the production of the pigment melaninnormally found in skin, eyes, and hair. Any one of a number of genes responsible for the production of melanin can lead to albinism.
We will sort out the confusion surrounding these terms and help you get a better understanding. How Albinism Affects Vision Skin receives its color from cells called melanocytes. When a person is unable to produce melanin, he or she may be diagnosed with a condition known as albinism.
This is an inherited, congenital condition that comes in different forms as a result of several genetic variations and can affect both men and women, regardless of nationality or ethnic origin. Ocular albinism and oculocutaneous albinism are two of the most common forms of this disorder. Individuals with oculocutaneous albinism will have very minimal if any pigmentation, which results in skin that is very pale to pink, hair that is platinum or white, and sometimes exhibit a pink or lavender tint to the eyes.
People with ocular albinism may have skin and hair that is close to normal in appearance, but their eyes lack melanin. Both forms of the disorder can result in complications with vision, although o culocutaneous albinism itself is commonly more recognizable than ocular albinism.
Visual Signs and Symptoms There are a number of symptoms and problems that people with albinism may face. These problems include a lack of pigment in the eyes, photophobia, foveal hypoplasia, optic nerve misrouting, nystagmus and strabismus.
Other vision problems such as astigmatism, farsightedness and nearsightedness will also have an effect on visual acuity. Although most people with albinism are able to see, they often suffer from reduced vision as a result of these eye conditions.
Minimal, or lack of, iris pigment is a major problem for people with albinism. Typically light enters the eye through the pupil while the iris, or the colored part of the eye, screens out excess light. When a person has little to no pigment in the iris, the light enters the eye unrestricted.
This causes an extreme sensitivity to light, which is known as photophobia.
The lack of pigment often causes the eyes to develop abnormally, which results in many of the eye problems that are associated with albinism. At the back of the retina, th ere is a small area that is called the macula.
The macula is what enables people to see objects clearly. At the center of this area is the fovea. When this is underdeveloped, it is known as macular or foveal hypoplasia and it will cause the person to lose some of his or her central vision.
Optic nerve misrouting is a condition in which the signals that are sent from retina to the brain are misrouted. This means that the signals do not follow the normal routes to the brain as they should.
This is a symptom that is often indicative of albinism and is more of a brain condition than one that affects the eyes.People who have ocular albinism are born with it.

Albinism is a rare group of genetic disorders that cause the skin, hair, or eyes to have little or no color. Albinism is also associated with vision problems.
About 1 in 18, to 20, people in. In birds, albinism has been defined as "a total lack of both melanins in feathers, eyes and skin as a result of an inherited absence of tyrosinase", however, this ignores the effects of other pigments and structural colours.
