Color Blind (Definition)

Ophthalmologist prefer to use the term color deficit as blindness conveys other meanings. Lowered color perception can be inherited (many forms), can result from advanced loss of retinal cells, inherited retinal disease, and some forms occur due to CNS injury. There are excellent tests for the various types and they can be functionally ...Read more

Explain the symptoms of color blindness?

Explain the symptoms of color blindness?

Color blindnes: A color blind person does not know of his problem until he compares himself with others. The visual acuity is usually normal. Color recognition is diminished along the axis of confusion for the type of deficiency. If you have this you could not be employed in color dependent occupations such as microcomponent assembly or fruit grading. ...Read more

What causes color blindness?

What causes color blindness?

Mostly genertic: In inherited color deficiency, a visual pigment has its spectrum of color reception altered to a small degree and to a large degree in those with high degree of this disorder. The photoreceptor count is the same, so the acuity is not lost - just the color recognition. There are a few less common color vision losses due to advanced retinal, optic nerve and CNS diseases. ...Read more

Nearsightedness is a recessive trait. red-green color blindness is a sex-linked recessive trait, what does this mean?

Nearsightedness is a recessive trait. red-green color blindness is a sex-linked recessive trait, what does this mean?

An Autosomal: Recessive disorder: Both parents are unaffected carriers of a mutant gene. Each of their children has a 25% chance of inheriting the mutant gene from both & having the disorder. X-linked recessive: Mom carries a defective gene on one of her X chromosomes. Each son has a 50% chance of inheriting the X chromosome with the mutant gene & having the disorder; each daughter, 50% of being a carrier. ...Read more

What is the treatment for color blindness?

None: Most color deficiency is inherited and suggested means such as a red contact lens over one eye merely shift the axis of color confusion to another pattern. Color blindness can be acquired in severe retinal disease like advanced diabetes and also optic nerve disease. Improvement is possible here if the underlying disease can be treated. ...Read more

Who gets color blindness most? Is it inherited?

Inherited in men: Most inborn color blindness is inherited with a frequency of 7.5% of men and 0.5% of women. Most do not know they have it until confronted with a situation in which they can compare their perceptions with others. It is due to an inherited alteration in the peak spectral perception of one of the three color elements of the eye. There is no treatment or cure. ...Read more

I have to do a genetic disorder report for class and was debating between color blindness and hemophilia. What are your opinions?

I have to do a genetic disorder report for class and was debating between color blindness and hemophilia. What are your opinions?

Both interesting: These are both fascinating diseases and the subject of much inquiry. Look on wikipedia and you will find much to talk about. The issues are quite different but the underpinning for each is genetic. The hemophilia has had impacts on history such as the family of queen victoria. Color deficiency has caused some famous accidents. Have fun. ...Read more

How does a person inherit the color blindness disorder?

Mutations (changes) : Changes in genes (regulatory elements) in every cell are inherited and may affect color vision. Thede changes are statistically much more significantt in males than females because the latter often have normal color vision genes to compensate. Inhered color blindness thus is more common in males, but color deficit also can result from some eye diseases, in either sex. ...Read more

Blindness (Definition)

Vision impairment and blindness are conditions in which a person cannot see well or see at all, even with glasses or contact lenses. If a person's best vision (with correction) out of either eye is only 20/70 - 20/200, he is impaired. If he can see no better than 20/200 or his visual field is no more than 20 degrees (severe "tunnel" vision), ...Read more

Loss Of Vision (Definition)

Loss of vision reflects the inability to perceive images. Such a phenotype can be due to occlusive or barriers to light (e.g. cataracts) through retinal alterations (e.g. wet macular degeneration) to optic nerve lesions (e.g. from a pituitary adenoma) to central nervous system ...Read more
