How is the disorder/condition inherited? Who can be a carrier?
•Color Blindness is an X-linked, recessive disorder•Almost always occurs in males with disease•Females can be carriers because they have two X chromosomes, but males either have it or don’t, because they have one X chromosome and one Y chromosome
What is the frequency of the disorder/condition?
• Color Blindness is most common in males• About 8% of men and 0.5% of women
experience it
What are the symptoms/effects & prognosis of someone with this disorder?
• The only symptom that is shown frequently in color blind patients is the not being able to see certain colors (depending on which type of color blindness you have)
• One example of a thing that people with color blindness have to do to cope with their disease is to memorize what order the lights on a traffic light go in.
(EXAMPLE OF WHAT A RED-GREEN COLORBLIND PERSON WOULD SEE)
How is the disorder/disease diagnosed?
• In order to diagnose the disease, and which type of color blindness a person has, they take tests like the ones below.
• If a person is color blind to a color, they will not be able to read what number, symbol, etc. that is in a different color
What is the treatment, if any?
• There is no treatment for color blindness• People with color blindness deal with their
disease because they have never had normal vision before
Is there a cure? If so, what is it? If not, what progress are scientists making toward
finding a cure?
• Color Blindness is not curable• You can test for color blindness while the baby
is not born but it can’t be treated after that
What are the different types of Color Blindness
• Dichromasy- Black and white vision; very rare• Red-green color blindness-inabitily to
distinguish red and green• Deuteranopia- *A type* of altered vision with
a confusion of greens and reds• Protanopia –The inability to see all four
primary colors rather limited to seeing blue and yellow
