80 faits surprenants sur le daltonisme

Faits concernant le daltonisme

Il y a environ 300 000 000 de daltoniens dans le monde. Beaucoup d'entre elles sont des hommes, mais un grand pourcentage sont des femmes. Contrairement à ce que le public peut penser, la majorité des daltoniens ont une vue saine. Le daltonisme est causé par une déficience d'un des trois types de cônes dans l'œil. Le plus souvent, il s'agit d'un manque de cônes rouges. Dans cet article, je vais vous présenter quelques faits intéressants sur le daltonisme que vous ne connaissiez pas auparavant.

Il s'agit de la forme la plus rare de daltonisme, les personnes atteintes de cette forme de daltonisme voient le rouge, le vert et le bleu comme du jaune.La deutéranomalie est causée par une mutation du chromosome X
36.Tritanopia is a rare form of color blindness which is inability to see the color red,tritanopia is caused by a genetic mutation in the gene OPN1SW
37.Total color blindness is extremely rare.

Color blind  and  Disease

38.Acquired color vision deficiency is caused by damage to the retina. It can be caused by retinal disease, optic nerve disease, brain disease or drug use.
39.Achromatopsia is a rare form of color blindness
40.Some colorblindness is caused by head trauma
41.Tetanus can make you color blind.
42.Tumors can cause color blindness. Tumors in the eye, or those anywhere in the body, can cause other health conditions and problems. This includes tumors that grow on the retina. Some of these tumors are cancerous and will spread to other parts of your body if not treated early enough. If you have a tumor growing inside your eyes, it could require surgery to remove it before it spreads too far and gets more dangerous to treat.
43.It’s estimated that less than 5 percent of people with aniridia have complete loss of color vision due to their lack of iris pigmentation; most people with aniridia have partial color blindness as one symptom among others related to vision problems caused by abnormal development during fetal stages.
44.Congenital stationary night blindness is a form of color vision deficiency (CVD) that is present at birth. It is also known as Achromatopsia and it causes a loss of color vision at night, but not during the day. This disease is rare and affects one in every 30,000 people in the United States alone.
45.Cone dystrophy is a rare form of color blindness that can affect one or more of the three cones in the eye. The condition is progressive and may eventually lead to complete loss of central vision.
Cone dystrophy is a rare form of color blindness that can affect one or more of the three cone cells in the eye. The condition is progressive and may eventually lead to complete loss of central vision.
46.Goldmann-Favre syndrome is a rare form of color blindness, which is a genetic condition that affects the retina. It is caused by mutations in the CEP290 gene. This gene helps control cell growth and division in the eye. Without it, some cells grow abnormally and others do not grow at all. The result is poor vision or complete blindness due to lack of sensory input from photoreceptor cells to the brain.
47.Eye damage from diabetes, multiple sclerosis, cataracts, macular degeneration, or retinal detachment can cause color blindness.
48.Leber congenital amaurosis (LCA) is a hereditary disease that causes severe vision loss from birth. The disease is caused by mutations in the RPE65 gene, which is responsible for making an enzyme necessary for the development of the retina. Without this enzyme, cells in photoreceptors — the light-sensitive cells at the back of your eye — cannot convert light into signals that travel through nerve fibers to your brain. The lack of this protein causes cell death and retinal degeneration resulting in impaired sight or complete blindness with few exceptions.


Le daltonisme est d'origine génétique

Faits concernant le daltonisme

49.Genetic color blindness is most often carried on the X chromosome, because that chromosome determines gender.
50.Rarely, a mutation in another chromosome can cause color blindness.
51.Genetic colorblindness is something that is present at birth and a person has for their entire life.
52.Red-green color blindness can be inherited, but it can also occur spontaneously in later life.
53.Red-green color blindness is caused by the absence or malfunction of the red (or green) cones in the retina.
54.People can be born with a genetic mutation that causes colorblindness, or an injury to the head can result in damage to the retina or optic nerve, which can cause damage and thus lead to color vision deficiency.
55.People may also experience night blindness when they have genetic colorblindness.
56.If a woman has a genetic mutation that causes her to be red-green colorblind, she will not pass it on to her sons but she could pass it on to her daughters, who would be carriers of the mutated gene but not probably have any issues unless they married another carrier and their son inherited two mutated genes.

Le daltonisme et la médecine

Faits concernant le daltonisme

57.Acetazolamide is a diuretic and it can cause color blindness. It’s used to treat glaucoma, seizures, and high blood pressure.
58.Aminophenazone is a commonly used drug in the treatment of fever and pain. However, it can also cause color blindness. If you are taking this medication and notice any changes in vision, talk to your doctor right away.
59.Color blindness is not severe but may be temporary. There is no treatment for it at this time, so if you experience any symptoms of color blindness while taking aminophenazone or another medicine that causes color blindness, such as sulfonamides or quinine derivatives (for example: Klacid® or Coartem®), see a doctor immediately.
60.Antimalarial medicines, such as chloroquine and hydroxychloroquine, are the most common medicines that cause color blindness. These drugs are used to treat malaria and rheumatic diseases like lupus in addition to psoriasis.
61.Chloroquine and hydroxychloroquine has been linked with an increase in color vision defects for some people who take it regularly for long periods of time (more than 6 months). This is because chloroquine destroys cells responsible for creating red light sensitivity in our eyes—the same cells that help us see green, blue and yellow colors well too. You might notice this as difficulty distinguishing between reds and greens/blues when driving at night or on dark roadsides where street lights are few and far between but there’s still plenty of ambient light pollution (from traffic signals etc.).
62.Dapsone can cause color blindness or other side effects such as headaches and blurred vision. You should take dapsone with food to avoid stomach upset if you experience these effects while taking this medication.
63.Ethambutol is an antibiotic used to treat tuberculosis.It can cause the inability to distinguish between red and green.
64.Isoniazid can cause color blindness, which is a loss of vision in one or more colors on the visible spectrum (red, green, blue). 
Para-aminosalicylic acid is an antibiotic that is used to treat tuberculosis. It’s also used to treat acne, but the side effect of this medicine can be color-blindness. 
65.Phenothiazines are a class of antipsychotic drugs that can cause color-blindness. They’re used to treat schizophrenia and other mental illnesses, as well as nausea and vomiting.
66.Phenothiazines are more likely to cause color blindness in people who have never had the condition before. Most people who have been diagnosed with color blindness will not experience any further changes in their vision after taking phenothiazines for a long time.

77.People who have red-green color vision deficiencies may react faster than others when it comes to driving cars, as they’re more likely to notice brake lights or stop signs ahead of time due to their heightened awareness of brightness and movement in the world around them.

78.Some studies have shown that musicians might be more likely to be colorblind than non-musicians because they need to focus on sounds instead of colors when performing music (or vice versa).

79.Colorblindness can be an advantage for people who work in the medical field.

80.Some people believe that being colorblind may give them an advantage in certain careers such as sales or marketing, but this is not true at all! Salespeople need to use all of their senses, including sight, so being colorblind will not help them in any way when selling products or services.

Conclusion

Often colorblindness is mentioned as a reason to discontinue a certain product or byproduct. While it’s true that people with a complete inability to see color don’t use certain products, it’s also important to remember those who enjoy certain items even though they can’t see the color. That’s why it’s so critical to know the facts about color blues, and recognize just how much of a role these play in our daily lives.
