Ocular Albinism is a type of albinism that affects mostly vision. It commonly comes with the lack of melanin in the skin that occurs in regular albinism.
Ocular albinism primarily affects the eyes, leading to visual impairments such as reduced sharpness, sensitivity to light, and issues with depth perception. It is characterized by a lack of pigmentation in the retina, which can result in abnormal development of the optic nerve pathways. While the condition primarily impacts vision, it may also be associated with other features, such as lighter skin and hair, although these are less pronounced compared to other forms of albinism.
Its free with operation happy eyes if you have a medical condition such as coloboma or ocular albinism.
Chromosome 9.
as far as i know, it ic called albinisim. but there are different types oculocutaneous albinism, which affets the skin AND the eyes, and also ocular albinism which only affects the eyes. i have also seen the word "hypopigmentation" thrown arround quite a bit
No.Most forms of albinism are the result of the biological inheritance of genetically recessive alleles (genes) passed from both parents of an individual, though some rare forms are inherited from only one parent. There are other genetic mutations which are proven to be associated with albinism. All alterations, however, lead to changes in melanin production in the body.The chance of offspring with albinism resulting from the pairing of an organism with albinism and one without albinism is low. However, because organisms can be carriers of genes for albinism without exhibiting any traits, albinistic offspring can be produced by two non-albinistic parents. Albinism usually occurs with equal frequency in both genders. An exception to this is ocular albinism, which it is passed on to offspring through X-linked inheritance. Thus, ocular albinism occurs more frequently in males as they have a single X and Y chromosome, unlike females, whose genetics are characterized by two X chromosomes.There are two different forms of albinism; a partial lack of the melanin is known as hypomelanism, or hypomelanosis and the total absence of melanin is known as amelanism or amelanosis.(Source wikipedia)
The word that means relating to the eye is "ocular." It is derived from the Latin word "oculus," which also means eye. Ocular is commonly used in medical contexts, such as ocular health or ocular diseases, to refer specifically to eye-related matters.
There are two types of albinism that can be found in a human. The primary type is oculocutaneous albinism, which is what most people think of when they think of an albino. It can exist in various levels of lack of pigment, from a complete lack of any pigment to a varying degree of that lack. It really isn't 'part' albino, but it is not a partial situation. A human being can have ocular albinism, which affects only the eyes and not the rest of the body.
Albinism doesn't affect a person's life expectancy. People with albinism may be limited in their activities because they can't take exposure to the sun, but their overall lifespan should remain unchanged.
Ocular toxicity is routinely assessed in toxicology studies conducted for regulatory purposes. Anatomical and physiological differences between species can affect the nature of ocular effects observed following intended or unintended exposure of ocular tissues to xenobiotics. Ocular toxicity in experimental animals provides a concise reference for ocular anatomy and physiology of different species, which will contribute to the design and interpretation of toxicological studies.
Ocular albinism (OA1) is caused by a genetic defect on chromosome 11 of the GPR143 gene. Oculocutaneous albinism type 2 (OCA2 or P gene albinism) results from a genetic defect on chromosome 15 in the P protein that helps the tyrosinase enzyme to function. Oculocutaneous albinism type 3 (OCA3) is rarely described and results from a genetic defect on chromosome 9 in TYRP1, a protein related to tyrosinase. Oculocutaneous albinism type 4 (OCA4) results from a genetic defect in chromosome 5 at position 13.3, in the SLC45A2 protein that helps the tyrosinase enzyme to function.
It is passed on from mother or father to child if the parents are albino, or if the mother carries the gene for albinism. The father cannot carry the gene as only woman are able to be carriers. Therefore, even if both parents are normal, the child can be albino (because the mother obviously carries the gene for albinism). :D
