Color blindness is usually an inherited disorder affecting the color-sensitive cells called photopigments
located within the cone shaped cells of the retina. These cone shaped cells are sensitive to three types of wave-lengths; long (red), medium (green)
and short (blue). Each of these wavelengths is identified and processed by their respective cone shaped cells as the colors red, green or blue. If any
of these cone shaped receptor cells are damaged or missing due to disease or as a result of a genetic event the impact will be expressed on an individual's
ability to distinguish between the different shades of colors. Certain types of color blindness are currently only treatable through the use of special light
altering glasses or contacts, however there are new studies and recent research efforts that are showing promising results in the treatment, or even eventual
cure of this disorder through a simple injection.
According to the American Academy of Ophthalmology successful gene therapy treatments have been undertaken in
monkeys suffering from color blindness. The new treatment consists of an injection into the clear fluid of the eye called the vitreous humor. This injection
contains a virus that has no known negative effect on humans. This virus is called the adeno-associated virus. Once injected, the virus locates the damaged
part of the retina and treats it by delivering the necessary genes required to improve or even restore the retina's cone cells. Although this gene therapy
treatment has had successful results in rendering monkeys more receptive to certain colors further testing is required. Researchers need to determine whether
only treating the retina is enough to overcome the effects of the disorder or whether there are other locations in the anatomy of the eye that require
According to the A.A.O. the colorblindness specialists involved in this research are "cautiously optimistic" about the early results of this form of treatment.
Interestingly enough the treatment could receive approval for human trials to begin as early as 2017. If these specialists are successful in developing an effective
treatment protocol one could expect the roll out of a potential treatment or cure for this disorder that affects approximately 8% of males and 1% of females
Color blindness, as research understand it today, is a disorder that impacts one of the most complicated organs of our body; however with the right type of research,
innovation and development we may one day cure it and label it as a disorder of the past.
Color blindness afflicts approximately 8% of all males and less than 1% of all females. What does it really mean to be color blind? To address this question letís go back a couple hundred years to a man named John Dalton and his observation and discovery of color blindness.
Red-Green colorblindness is the most common type of inherited color blindness affecting approximately 6% of males and less than 1% of females. From those impacted by this abnormality a few cases are due to protanomaly and protanopia. What is the difference between the two?
According to Contact Lens King, deuteranomaly is the most common type of color blindness and is caused by an incidence of defective photoreceptor cone cells that are responsible for the processing of medium wavelengths of light. These specific photoreceptor cells are responsible for the interpretation of the color green along with its various hues. However, the severity of the color blindness disorder will dictate how extreme the color green is misinterpreted, and potentially inhibited.Let's look at the symptoms related to this specific disorder along with its causes and possible treatments.
There is currently no cure for color blindness, however if researchers are able to prove this new gene therapy treatment is successful a potential cure for color blindness might be in sight. Once injected, the virus locates the damaged part of the retina and treats it by delivering the necessary genes required to improve or even restore the retina's cone cells. To find out more about this treatment and how it is being tested read this article.
A color blind test is administered in order to determine if a person suffers from the inability to clearly differentiate colors. Color blindness itself is not a form of blindness but just a disorder that affects a person's ability to distinguish certain colors. In an effort to help you perform a quick test to determine whether or not you are impacted by color blindness Contact Lens King is providing an Ishihara Color Blind Test. Upon submission of the test we will provide you with a result page indicating whether or not you are likely suffering from vision color deficiency and if you do which steps should be taken.
