Albinism is a genetic condition affecting melanin production, the pigment responsible for skin, hair, and eye color. This leads to a characteristic set of features.
Key Characteristics of Albinism
-
Reduced or Absent Melanin: The hallmark of albinism is significantly less melanin than normal, or its complete absence. This impacts the coloring of various body parts.
-
Very Pale Skin: Affected individuals typically have extremely pale skin, prone to sunburn and skin cancer. The degree of paleness can vary.
-
Light-Colored Hair: Hair is usually very light blonde, brown, or reddish, reflecting the lack of melanin.
-
Light-Colored Eyes: Eye color varies, often presenting as pink, light blue, green, gray, or light brown. The irises lack sufficient pigment, allowing light to shine through, which can cause light sensitivity.
-
Visual Impairment: Many with albinism experience vision problems. These can include:
- Nystagmus: Involuntary eye movements.
- Strabismus: Misalignment of the eyes.
- Photophobia: Increased sensitivity to light.
- Reduced Visual Acuity: Impaired sharpness of vision.
- Foveal Hypoplasia: Underdevelopment of the central part of the retina responsible for sharp central vision.
-
Variable Presentation: The exact appearance can vary widely. Skin tone, hair color, and eye color differ between individuals.
Oculocutaneous Albinism (OCA)
Many references highlight OCA, where impaired melanin synthesis affects the skin, hair, and eyes. Characteristic ocular features, like those listed above, are frequently observed.
Further Considerations
While albinism is a lifelong condition, it doesn't worsen over time. Individuals with albinism require special care to protect their skin from sun damage and may need vision correction or other support to manage vision impairment.
