Which type of albinism is most common?
Types of albinism
- Oculocutaneous albinism (OCA), the most common type, means a person inherited two copies of a mutated gene — one from each parent (autosomal recessive inheritance).
- Ocular albinism is mainly limited to the eyes, causing vision problems.
- Albinism related to rare hereditary syndromes can occur.
What is the difference between ocular albinism and oculocutaneous albinism?
Oculocutaneous albinism involves both the skin and the eyes, whereas ocular albinism mainly affects the eyes with minimal to no skin involvement. The primary morbidity of both oculocutaneous albinism and ocular albinism is eye related.
Are there different levels of albinism?
There are many different types of albinism, but the term typically refers to two: oculocutaneous albinism (OCA) and ocular albinism. There are three types of OCA which are referred to as OCA type 1, OCA type 2, and OCA type 3.
What limitations does a person with albinism have?
Albinism can also cause a variety of visual impairments including involuntary back-and-forth movements of the eyes (nystagmus), inability to focus both eyes on a single point (strabismus), extreme near/farsightedness, and sensitivity to light, or photophobia.

What is the difference between albinism and leucism?
Albinism is a condition which is characterized by the absence of melanin in the skin, hair and eyes. Therefore, albinism differs from leucism. In albinism, melanin is absent even in the eyes of the animal. But, in leucism, melanin is present in the eyes of the animal. Albinism is a result of a defect in genes that produce or distribute melanin.
What is melananism?
