Two naturally color-blind monkeys are now able to see in full color after being treated via gene therapy.  The researchers injected a gene-carrying virus into the monkeys’ eyes.   While, after treatment, their vision did not reach that of monkeys born with normal genes, in about 20 weeks they attained full color vision and have shown no harmful side effects.  The researchers suggested that difference in treated versus untreated monkeys may point toward the need for improvement in developing the treatment.  Researchers used the same test for color-blindness as used with very young children, the Cambridge Color Test.  Monkeys were rewarded with grape juice for tracing the pattern of shaped on a touch screen when they saw them.  Fore more information, see National Geographic News.

  1. OMG! That is flippin’ amazing. I hope they will be able to tweak this research to make it usable for humans if needed. 🙂

    wow, how amazing is that! I have a horror of using animals for scientific testing, purposes etc, and yet when you read about results like this……? it is so very debateable. great for the wee monkeys.

    could mean a lot to my friend who is color blind. The speed of genetic research could mean he might be able to see true colors in his lifetime. What an event that would be.

    Let us all hope that this gene therapy works well on humans as it works on monkeys. If this does happen, it could work wonders for all the unfortunate differently-abled humans all over the world. It could change the face of humanity…

    That’s a great outcome….wish u the best in the future with more and more discoveries that could help with some of the incurable illnesses…

    That is an amazing step in scientific research. I read earlier today about how paralyzed mice were brought back to mobility with electric stimulation and a type of physical therapy. Science truly is a wonderful thing.

    Great. Hope in the future all the disease will be cured by gene therapies..
